| 1 | Crack monitoring method based on Cu coating sensor and electrical potential technique for metal structure显示文摘Advanced crack monitoring technique is the cornerstone of aircraft structural health monitoring.To achieve real-time crack monitoring of aircraft metal structures in the course of service,a new crack monitoring method is proposed based on Cu coating sensor and electrical potential difference principle.Firstly,insulation treatment process was used to prepare a dielectric layer on structural substrate,such as an anodizing layer on 2A12-T4 aluminum alloy substrate,and then a Cu coating crack monitoring sensor was deposited on the structure fatigue critical parts by pulsed bias arc ion plating technology.Secondly,the damage consistency of the Cu coating sensor and2A12-T4 aluminum alloy substrate was investigated by static tensile experiment and fatigue test.The results show that strain values of the coating sensor and the 2A12-T4 aluminum alloy substrate measured by strain gauges are highly coincident in static tensile experiment and the sensor has excellent fatigue damage consistency with the substrate.Thirdly,the fatigue performance discrepancy between samples with the coating sensor and original samples was investigated.The result shows that there is no obvious negative influence on the fatigue performance of the 2A12-T4 aluminum alloy after preparing the Cu coating sensor on its surface.Finally,crack monitoring experiment was carried out with the Cu coating sensor.The experimental results indicate that the sensor is sensitive to crack,and crack origination and propagation can be monitored effectively through analyzing the change of electrical potential values of the coating sensor. | Hou Bo He Yuting Cui Ronghong Gao Chao Zhang Teng | 2015 | Chinese Journal of Aeronautics2015，28，3： | 10 |
| 2 | Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype. | Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu | 2021 | Cell Research2021，31，3： | 9 |
| 3 | Structural Surface Crack Monitoring Method Based on Electrical Potential Technique and Modern Surface Technology显示文摘Crack monitoring plays a great role in modern structural health monitoring, however, most of the conventional crack inspections have disadvantages in terms of the accuracy, expense, reliability, durability and level of instrumentation required. Thus, development of a simple and reliable crack inspection technique that allows continuous monitoring has been desired. In this paper, electrical potential technique and modern surface technology are employed together to develop a new structural surface crack monitoring method. A special crack monitoring coating sensor based on electrical potential technique was deposited on the hot spot of the structure by modern surface technology. The sensor consists of three layers: the isolated layer, the sensing layer and the protective layer. The isolated layer is prepared by anodic oxidation technology, the sensing layer is made of ion plated copper, and the protective layer is made of silicone. The thickness of each layer is at micrometer magnitude. The electrical conductivity of the sensor is very stable, and the fatigue performance of the specimen with or without coating sensor is nearly unchanged. The crack monitoring experiment result shows that there are two sudden rises of the coating sensor electrical potential values, corresponding to different stages of the crack initiation and propagation. Since the width of the surface coating sensor is only 0.5 mm, this crack monitoring sensor can detect the propagation of cracks less than 0.5 mm long. The method proposed takes the simplicity of electrical potential technique and can monitor surface crack of nearly all kinds of structures precisely. The results of this paper may form the basis of a new crack monitoring system. | CUI Ronghong HE Yuting YU Zhiming LI Hongpeng SHU Wenjun DU Jinqiang | 2011 | Chinese Journal of Mechanical Engineering2011，24，4： | 7 |
| 4 | No expenditure difference among patients with liver cancer at stageⅠ-ⅣV:Findings from a multicenter cross-sectional study in China显示文摘Objective:The number of liver cancer patients in China accounts for more than half of the world.However,China currently lacks national,multicenter economic burden data,and meanwhile,measuring the differences among different subgroups will be informative to formulate corresponding policies in liver cancer control.Thus,the aim of the study was to measure the economic burden of liver cancer by various subgroups.Methods:A hospital-based,multicenter and cross-sectional survey was conducted during 2012・2014,covering 39 hospitals and 21 project sites in 13 provinces across China.The questionnaire covers clinical information,sociology,expenditure,and related variables.All expenditure data were reported in Chinese Yuan(CNY)using 2014 values.Results:A total of 2,223 liver cancer patients were enrolled,of whom 59.61%were late-stage cases(III-IV),and 53.8%were hepatocellular carcinoma.The average total expenditure per liver cancer patient was estimated as 53,220 CNY,including 48,612 CNY of medical expenditures(91.3%)and 4,608 CNY of non-medical expenditures(8.7%).The average total expenditures in stage I,H,m and stage IV were 52,817 CNY,50,877 CNY,50,678 CNY and 54,089 CNY(P>0.05),respectively.Non-medical expenditures including additional meals,additional nutrition care,transportation,accommodation and hired informal nursing were 1,453 CNY,839 CNY,946 CNY,679 CNY and 200 CNY,respectively.The one-year out-of-pocket expenditure of a newly diagnosed patient was 24,953 CNY,and 77.2%of the patients suffered an unmanageable financial burden.Multivariate analysis showed that overall expenditure differed in almost all subgroups(P<0.05),except for sex,clinical stage,and pathologic type.Conclusions:There was no difference in treatment expenditure for liver cancer patients at different clinical stages,which suggests that maintaining efforts on treatment efficacy improvement is important but not enough.To fiirtherly reduce the overall economic burden from liver cancer,more effort should be given to primary and secondary prevention strategies. | Haike Lei Lin Lei Jufang Shi Yongzhong Wu Ling Liang Huiyao Huang Mei He Fangzhou Bai Maomao Cao Hui Qiu Yuting Wang Chengcheng Liu Jia Du Hong Wang Yan Zhang Mengdi Cao Ji Peng Ni Li Chunfeng Qu Min Dai Wanqing Chen Jie He | 2020 | Chinese Journal of Cancer Research2020，32，4： | 7 |
| 5 | In vivo flow cytometry reveals a circadian rhythm of circulating tumor cells显示文摘Circulating tumor cells(CTCs)is an established biomarker of cancer metastasis.The circulation dynamics of CTCs are important for understanding the mechanisms underlying tumor cell dissemination.Although studies have revealed that the circadian rhythm may disrupt the growth of tumors,it is generally unclear whether the circadian rhythm controls the release of CTCs.In clinical examinations,the current in vitro methods for detecting CTCs in blood samples are based on a fundamental assumption that CTC counts in the peripheral blood do not change significantly over time,which is being challenged by recent studies.Since it is not practical to draw blood from patients repeatedly,a feasible strategy to investigate the circadian rhythm of CTCs is to monitor them by in vivo detection methods.Fluoresce nee in vivo flow cytometry(IVFC)is a powerful optical technique that is able to detect fluoresce nt circulating cells directly in living animals in a noninvasive manner over a long period of time.In this study,we applied fluorescence IVFC to monitor CTCs noninvasively in an orthotopic mouse model of human prostate cancer.We observed that CTCs exhibited stochastic bursts over cancer progression.The probability of the bursting activity was higher at early stages than at late stages.We longitudinally monitored CTCs over a 24-h period,and our results revealed striking daily oscillations in CTC counts that peaked at the onset of the night(active phase for rodents),suggesting that the release of CTCs might be regulated by the circadian rhythm. | Xi Zhu Yuanzhen Suo Yuting Fu Fuli Zhang Nan Ding Kai Pang Chengying Xie Xiaofu Weng Meilu Tian Hao He Xunbin Wei | 2021 | Light(Science & Applications)2021，10，6： | 6 |

| 7 | Chemical formation and source apportionment of PM_(2.5) at an urban site at the southern foot of the Taihang mountains显示文摘The region along the Taihang Mountains in the North China Plain(NCP) is characterized by serious fine particle pollution. To clarify the formation mechanism and controlling factors, an observational study was conducted to investigate the physical and chemical properties of the fine particulate matter in Jiaozuo city, China. Mass concentrations of the water-soluble ions(WSIs) in PM_(2.5) and gaseous pollutant precursors were measured on an hourly basis from December 1, 2017, to February 27, 2018. The positive matrix factorization(PMF) method and the FLEXible PARTicle(FLEXPART) model were employed to identify the sources of PM_(2.5). The results showed that the average mass concentration of PM_(2.5) was 111 μg/m^(3) during the observation period. Among the major WSIs, sulfate, nitrate, and ammonium(SNA) constituted 62% of the total PM_(2.5) mass, and NO_(3)^(-) ranked the highest with an average contribution of 24.6%. NH_(4)^(+) was abundant in most cases in Jiaozuo. According to chemical balance analysis, SO_(2)-4, NO_(3)^(-), and Cl^(-) might be present in the form of(NH_4)_(2)SO_4, NH_4NO_3, NH_4Cl, and KCl. The liquid-phase oxidation of SO_(2) and NO_(2) was severe during the haze period. The relative humidity and pH were the key factors influencing SO_(4)^(2-) formation. We found that NO_(3)^(-) mainly stemmed from homogeneous gas-phase reactions in the daytime and originated from the hydrolysis of N_(2)O_5 in the nighttime, which was inconsistent with previous studies. The PMF model identified five sources of PM_(2.5) : secondary origin(37.8%), vehicular emissions(34.7%), biomass burning(11.5%), coal combustion(9.4%), and crustal dust(6.6%). | Xiaoyong Liu Mingshi Wang Xiaole Pan Xiyue Wang Xiaolong Yue Donghui Zhang Zhigang Ma Yu Tian Hang Liu Shandong Lei Yuting Zhang Qi Liao Baozhu Ge Dawei Wang Jie Li Yele Sun Pingqing Fu Zifa Wang Hong He | 2021 | Journal of Environmental Sciences2021，33，5： | 5 |
| 8 | Enhancement of Bio-based para-Xylene Selectivity in Catalytic Fast Pyrolysis of Cellulose Using a Surface-modified Mg/P/HZSM-5 Catalyst显示文摘With the growing consumption of oil, the production of /?-xylene(PX) from renewable biomass has gained significant attention recently. This work demonstrated that cellulose, a main component in lignocellulosic biomass, was directly converted into PX over the Mg/P surface-modified zeolites. The catalysts modified by the incorporation of P2O5 and MgO into HZSM-5(HZ) promoted the isomerization of zw-/o-xylenes to p-xylene. The PX selectivity was greatly enhanced using the modified zeolites due to the deactivation of external surface and the adjustment of pore entrance. In addition, the addition of methanol to cellulose was beneficial to increase the selectivity of xylenes due to the alkylation reactions and the Diels-Alder reactions between cellulose-derived furans and methanol-derived olefins. The highest PX yield of 10.7%(molar fraction) with a high PX selectivity in xylenes(97.1%) was obtained over the 10%Mg/5%P/HZ catalyst. The reaction pathway for the formation ofp-xylene was addressed according to the study of the key reactions and the characterization of catalysts. | WANG Yulan FAN Minghui ZHU Lijuan WANG Shengfei HE Yuting LI Quanxin | 2019 | Chemical Research in Chinese Universities2019，35，3： | 4 |
| 9 | Vertical distribution characteristics of dust aerosol mass concentration in the Taklimakan Desert hinterland显示文摘The different height mass concentrations of dust aerosol data from the atmosphere environment observation station(Tazhong Station)was continuously observed by instruments of Grimm 1.108,Thermo RP 1400a and TSP from January of2009 to February of 2010 in the Taklimakan Desert hinterland.Results show that:(1)The mass concentration value of 80m PM10was higher,but PM2.5and PM1.0concentrations at 80 m was obviously lower than 4 m PM10,and the value of 80 m PM1.0mass concentration was the lowest.(2)The PM mass concentrations gradually decreased from night to sunrise,with the lowest concentration at 08:00,with the mass concentration gradually increased,up to the highest concentration around18:00,and then decreased again.It was exactly the same with the changes of wind speed.(3)The high monthly average mass concentration of TSP mainly appeared from March to September,and the highest concentration was in April and May,subsequently gradually decreased.Also,March–September was a period with high value area of PM monthly average mass concentration,with the highest monthly average mass concentration of 846.0μg/m3for 4 m PM10appeared in May.The concentration of PM10was much higher than those of PM2.5and PM1.0at 80 m.There is a small difference between the concentration of PM2.5and PM1.0.Dust weather was the main factor which influenced the concentration content of the different diameter dust aerosol,and the more dust weather days,the higher content of coarse particle,conversely,fine particle was more.(4)The mass concentration of different diameter aerosols had the following sequence during dust weather:clear day | XinChun Liu YuTing Zhong Qing He XingHua Yang Ali Mamtimin Wen Huo | 2013 | Research in Cold and Arid Regions2013，5，6： | 3 |
| 10 | Performance study on three-stage power system of compressed air vehicle based on single-screw expander显示文摘A new compressed-air engine system based on three-stage single screw expander was proposed to improve the performance of power system.Three different structure styles were presented,and the studies on the power performance and the distribution of expansion ratios between stages were carried out by programming and mathematical modeling of each style.Research results indicated that the best matches of expansion ratios with equal heat temperature for the air tank of pressure 30 MPa were seven-five-three for'first-stage heating'style,eight-five-three for'two-stage heating'style and five-five-four for'three-stage heating'style,respectively.Results also showed that heating up inlet air or increasing the expander efficiency might improve the power performance.The output power of the'two-stage heating'style is far higher than that of'first-stage heating'style and is a little lower than that of'three-stage heating'style.The new system showed good structure and power performances. | HE Wei,WU YuTing ,MA ChongFang&MA GuoYuan Key Laboratory of Enhanced Heat Transfer and Energy Conservation,Ministry of Education,and Key Laboratory of Heat Transfer and Energy Conversion,Beijing Municipality,College of Environmental and Energy Engineering,Beijing University of Technology,Beijing 100124,China | 2010 | Science China(Technological Sciences)2010，53，8： | 3 |
| 11 | INTERFERENCE BY NON-HOST PLANT ROOTS AND ROOT EXUDATES IN THE INFECTION PROCESSES OF PHYTOPHTHORA NICOTIANAE显示文摘Crop rotations are widely used because they can significantly reduce the incidence of pests and diseases.The interactions between non-host roots and pathogens may be key in the inhibition of soilborne pathogens in crop rotations.Interactions between fennel(Foeniculum vulgare)roots/root exudates and Phytophthora nicotianae were investigated because of the known allelopathy between fennel and tobacco(Nicotiana tabacum).The effects of the key compounds in the fennel rhizosphere on the mycelial growth and zoospore behavior of P.nicotianae were assessed.The roots of fennel attracted P.nicotianae zoospores and inhibited their motility and the germination of cystospores,with some cystospores rupturing.4-ethylacetophenone,vanillin and N-formylpiperidine were consistently identified in the fennel rhizosphere and were found to interfere with the infection of P.nicotianae,especially vanillin.Hyphae treated with these compounds produced more abnormal branches and accumulated reactive oxygen species.These interspecific interactions between non-host roots and pathogens were found to be an important factor in the inhibition by fennel of infection by P.nicotianae. | Yuxin YANG He ZHANG Yuting FANG Ying LI Xinyue MEI Huichuan HUANG Fei DU Shusheng ZHU Min YANG Yixiang LIU | 2021 | Frontiers of Agricultural Science and Engineering2021，8，3： | 3 |
| 12 | A male-ABCD algorithm for hepatocellular carcinoma risk prediction in HBs Ag carriers显示文摘Objective: Hepatocellular carcinoma(HCC) development among hepatitis B surface antigen(HBs Ag) carriers shows gender disparity, influenced by underlying liver diseases that display variations in laboratory tests. We aimed to construct a risk-stratified HCC prediction model for HBs Ag-positive male adults.Methods: HBs Ag-positive males of 35-69 years old(N=6,153) were included from a multi-center populationbased liver cancer screening study. Randomly, three centers were set as training, the other three centers as validation. Within 2 years since initiation, we administrated at least two rounds of HCC screening using Bultrasonography and α-fetoprotein(AFP). We used logistic regression models to determine potential risk factors,built and examined the operating characteristics of a point-based algorithm for HCC risk prediction.Results: With 2 years of follow-up, 302 HCC cases were diagnosed. A male-ABCD algorithm was constructed including participant's age, blood levels of GGT(γ-glutamyl-transpeptidase), counts of platelets, white cells,concentration of DCP(des-γ-carboxy-prothrombin) and AFP, with scores ranging from 0 to 18.3. The area under receiver operating characteristic was 0.91(0.90-0.93), larger than existing models. At 1.5 points of risk score,26.10% of the participants in training cohort and 14.94% in validation cohort were recognized at low risk, with sensitivity of identifying HCC remained 100%. At 2.5 points, 46.51% of the participants in training cohort and 33.68% in validation cohort were recognized at low risk with 99.06% and 97.78% of sensitivity, respectively. At 4.5 points, only 20.86% of participants in training cohort and 23.73% in validation cohort were recognized at high risk,with positive prediction value of 22.85% and 12.35%, respectively.Conclusions: Male-ABCD algorithm identified individual's risk for HCC occurrence within short term for their HCC precision surveillance. | Yuting Wang Minjie Wang He Li Kun Chen Hongmei Zeng Xinyu Bi Zheng Zhu Yuchen Jiao Yong Wang Jian Zhu Hui Zhao Xiang Liu Chunyun Dai Chunsun Fan Can Zhao Deyin Guo Hong Zhao Jianguo Zhou Dongmei Wang Zhiyuan Wu Xinming Zhao Wei Cui Xuehong Zhang Jianqiang Cai Wanqing Chen Chunfeng Qu | 2021 | Chinese Journal of Cancer Research2021，33，3： | 3 |
| 13 | Analysis of mass concentration of atmospheric particulate matter in a sandstorm course and its affecting factors in the Taklimakan Desert显示文摘During the course of a major sandstorm from April 17 to April 23,2008 in the Taklimakan Desert,data pertaining to the mass concentrations of different-sized atmospheric particulate matter were observed continuously with Grimm 1.108,Thermo RP 1400a,TSP,and CAWS-600 instruments.The results showed that:(1) during the entire sandstorm process there were some differences between the daily mean particle concentration peaks and the hourly mean particle concentration peaks because the actual sandstorm lasted for only about 4 hr,whereas more particles were accumulated in the floating dust days before and after the actual sandstorm;(2) the intensity of the sandstorm was enhanced with the increase of wind speed,and this was related to the peak mass concentrations of atmospheric particulate matter;the wind speed directly affected the concentration of atmospheric particulate matter:the higher the wind speed,the higher the mass concentration(>0.23 μm was 39,496.5 μg/m 3,and >20.0 μm was 5,390.7 μg/m 3);(3) the concentration changes of PM 10 and TSP were also related to the course and intensity of the sandstorm;and(4) the mass concentration of atmospheric particulate matter had the following sequence during the dust weather:clear day < floating dust < floating and blowing dust < sandstorm.Temperature,relative humidity,and barometric pressure are important factors affecting the strength of storms,which could also indirectly affect the concentration change of atmospheric particulate matter. | XinChun Liu YuTing Zhong Qing He XingHua Yang Ali Mamtimin Wen Huo | 2012 | Research in Cold and Arid Regions2012，4，3： | 3 |

| 16 | Effects of Angelica sinensis extracts on lipid oxidation in fish feeds and growth performance of juvenile Jian carp(Cyprinus carpio var. Jian)显示文摘The study was to explore the effect of the extracts of Angelica sinensis(EAs) on lipid oxidation in fish feeds compared with ethoxyquin(EQ) and the effect of dietary EAs on growth performance of carp(Cyprinus carpio var. Jian). Firstly, fish feeds were respectively added with EQ, and ethyl ether extract ethyl acetate extract(EAE), acetone extract, ethanol extract(EE) and aqueous extract(AQE) of Angelica sinensis, except for the control. The results showed that EAs and EQ inhibited lipid oxidation in fish feed(P < 0.05). Of all of the examined EAs, EAE showed the strongest protective effects against lipid oxidation(P < 0.05). Moreover, EAE at high concentrations showed a stronger effect on lipid oxidation compared with EQ(P < 0.05). Then, 7 experimental diets respectively supplemented with 0.0, 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 g/kg of EAE were fed to the respective treatment groups for 30 d. Four replicates were performed for each treatment group; 20 carp(mean weight: 12.10 ± 0.13 g) were in each replicate. The result indicated that dietary EAE improved the growth performance in carp(P < 0.05). The appropriate con centration of EAE for carp growth was estimated to be 3.643 g/kg diet. Thus, EAE could be used as a natural antioxidant in feeds for Jian carp. | Huatao Li Dandan Yang Zhihao Li Mingquan He Fengyi Li Jun Jiang Siyi Tang Peiyuan Peng Wenhao Du Yuting Ma Ying Liu | 2019 | Animal Nutrition2019，，1： | 2 |
| 17 | Reply to Comment on “In vivo flow cytometry reveals a circadian rhythm of circulating tumor cells”显示文摘Dear Editor,We thank Niedre et al.for their correspondence regarding our recent paper1.They proposed a point that the temporal distribution of circulating tumor cells(CTCs)monitored by diffuse in vivo flow cytometry in a multiple myeloma mouse model in their previous work2 might be different from our results.Niedre et al.claimed that CTC detection statistics deviated from Poisson but did not found circadian variations in CTC numbers in a multiple myeloma mouse model.They also cite another literature by Juratli.et al.3,in which the authors reported that CTC numbers did not always correlate with tumor size during cancer progression.However,by establishing an orthotopic mouse model of prostate cancer and utilizing the technology in vivo flow cytometry(IVFC),we found CTCs exhibited bursting activity and daily oscillation in an orthotopic model of prostate cancer. | Xi Zhu Yuanzhen Suo Yuting Fu Fuli Zhang Nan Ding Kai Pang Chengying Xie Xiaofu Weng Meilu Tian Hao He Xunbin Wei | 2021 | Light(Science & Applications)2021，10，10： | 2 |

| 20 | Temporal and spatial variations of net primary productivity and its response to groundwater of a typical oasis in the Tarim Basin, China显示文摘Net primary productivity (NPP) of the vegetation in an oasis can reflect the productivity capacity of a plant community under natural environmental conditions. Owing to the extreme arid climate conditions and scarce precipitation in the arid oasis regions, groundwater plays a key role in restricting the development of the vegetation. The Qira Oasis is located on the southern margin of the Taklimakan Desert (Tarim Basin, China) that is one of the most vulnerable regions regarding vegetation growth and water scarcity in the world. Based on remote sensing images of the Qira Oasis and daily meteorological data measured by the ground stations during the period 2006-2019, this study analyzed the temporal and spatial patterns of NPP in the oasis as well as its relation with the variation of groundwater depth using a modified Carnegie Ames Stanford Approach (CASA) model. At the spatial scale, NPP of the vegetation decreased from the interior of the Qira Oasis to the margin;at the temporal scale, NPP of the vegetation in the oasis fluctuated significantly (ranging from 29.80 to 50.07 g C/(m2•month)) but generally showed an increasing trend, with the average increase rate of 0.07 g C/(m2•month). The regions with decreasing NPP occupied 64% of the total area of the oasis. During the study period, NPP of both farmland and grassland showed an increasing trend, while that of forest showed a decreasing trend. The depth of groundwater was deep in the south of the oasis and shallow in the north, showing a gradual increasing trend from south to north. Groundwater, as one of the key factors in the surface change and evolution of the arid oasis, determines the succession direction of the vegetation in the Qira Oasis. With the increase of groundwater depth, grassland coverage and vegetation NPP decreased. During the period 2008-2015, with the recovery of groundwater level, NPP values of all types of vegetation with different coverages increased. This study will provide a scientific basis for the rational utilization and sustainable management of groundwater resources in the oasis. | SUN Lingxiao YU Yang GAO Yuting ZHANG Haiyan YU Xiang HE Jing WANG Dagang Ireneusz MALIK Malgorzata WISTUBA YU Ruide | 2021 | Journal of Arid Land2021，13，11： | 2 |
