| 1 | Urban expansion in China and its effect on cultivated land before and after initiating'Reform and Open Policy'显示文摘Urbanization in China has expanded at an unprecedented speed since the declaration of 'Reform and Open Policy'and presented many challenges. Unbalanced regional development, appearance of super megacities and concomitant problems,and conflicts between urbanization and cultivated land protection are three critical problems that Chinese urbanization has to face. To develop new plans for foreseeable future urbanization in China, it is critical to understand the evolving history of cities across China. This study maps urban expansion of 60 typical Chinese cities based on large amount of remote sensing data and the labor-intensive image interpretation method, in order to understand the history of urban expansion from the 1970 s to 2013.Results showed that area of cities expanded 5.23 times compared to their area in the 1970 s. Urban expansion in China accelerated three times(1988–1996, 1999–2006, and 2009–2011) and decelerated three times(1997–1998, 2007–2008, and 2012–2013) over the 40 years. The urban area of South China expanded most significantly 9.42 times, while the urban area in Northeast China expanded only 2.37 times. The disparity among different administrative ranks of cities was even greater than(3.81 times) the differences among different regions. Super megacities have been continuously expanding at a fast rate(8.60-fold), and have not shown obvious signs of slowing down. The proportion of cultivated land among the land sources for urban expansion decreased to a small extent in the 1990 s, but cultivated land continues to be the major land source for urban expansion. Effective future urbanization needs controlling the expansion scale of large cities and reasonably developing medium and small cities, as well as balancing regional development. | ZHANG ZengXiang WEN QingKe LIU Fang ZHAO XiaoLi LIU Bin XU JinYong YI Ling HU ShunGuang WANG Xiao ZUO LiJun LI Na LI MinMin SHI LiFeng ZENG Tian JU HongRun | 2016 | Science China Earth Sciences2016,59,10: | 12 |
| 2 | Spatial and temporal variations of coastlines in northern China (2000-2012)显示文摘This study examined the spatial distribution of the continent coastline in northern China using remote sensing and GIS techniques,and calculated the fractal dimension of the coastline by box-counting method,with a time span from 2000 to 2012.Moreover,we analyzed the characteristics of spatial-temporal changes in the coastline's length and fractal dimension,the relationship between the length change and fractal dimension change,and the driving forces of coastline changes in northern China.During the research period,the coastline of the study area increased by 637.95 km,at a rate of 53.16 km per year.On the regional level,the most significant change in coastline length was observed in Tianjin and Hebei.Temporally,the northern China coastline grew faster after 2008.The most dramatic growth was found between 2010 and 2011,with an increasing rate of 2.49% per year.The fractal dimension of the coastline in northern China was increasing during the research period,and the most dramatic increase occurred in Bohai Rim.There is a strong-positive linear relationship between the historical coastline length and fractal dimension(the correlation coefficient was 0.9962).Through statistical analysis of a large number of local coastline changes,it can be found that the increase(or decrease) of local coastline length will,in most cases,lead to the increase(or decrease) of the whole coastline fractal dimension.Civil-coastal engineering construction was the most important factor driving the coastline change in northern China.Port construction,fisheries facilities and salt factories were the top three construction activities.Compared to human activities,the influence of natural processes such as estuarine deposit and erosion were relatively small. | XU Jinyong ZHANG Zengxiang ZHAO Xiaoli WEN Qingke ZUO Lijun WANG Xiao YI Ling | 2014 | Journal of Geographical Sciences2014,24,1: | 10 |
| 3 | Urban Expansion in China Based on Remote Sensing Technology:A Review显示文摘Urban areas and its evolution are important anthropogenic indicators and human ecological footprints, and play decisive roles in environmental change analysis, global geo-conditional monitoring, and sustainable development. China has the highest rate of urban expansion and has emerged as an urban expansion hotspot worldwide. In this paper, the progress of studies on Chinese urban expansion based on remote sensing technology are summarized and analyzed from the aspects of urban area definition, remotely sensed imagery applied in urban expansion, monitoring methods of urban expansion, and urban expansion applications. Existing issues and future directions of Chinese urban expansion are discussed and proposed. Results indicate that: 1) The fusion of multi-source remotely sensed imagery is imperative to meet the needs of urban expansion with various monitoring terms and frequencies on different scales and dimensions. 2) To guarantee the classification accuracy and efficiency and describe urban expansion and its influences on local land use simultaneously, the combination of visual interpretation and automatic classification is the tendency of future monitoring methods of urban areas. 3) Urban expansion data have become the prerequisite for recognizing the urban development process, excavating its driving forces, simulating and predicting the future development directions, and also is conducive to revealing and explaining urban ecological and environmental issues. 4) In the past decades, Chinese scholars have promoted the application of remote sensing technology in the urban expansion field, with data construction, methods and models developing from the quotation stage to improvement and innovation stage; however, an independent and consistent urban expansion data on the national scale with long-term and high-frequency(such as annual monitoring) monitoring is still lacking. | ZHANG Zengxiang LIU Fang ZHAO Xiaoli WANG Xiao SHI Lifeng XU Jinyong YU Sisi WEN Qingke ZUO Lijun YI Ling HU Shunguang LIU Bin | 2018 | Chinese Geographical Science2018,28,5: | 6 |
| 4 | The efficacy and safety of nimodipine in acute ischemic stroke patients with mild cognitive impairment: a double-blind, randomized,placebo-controlled trial显示文摘Nimodipine might be effective in subcortical vascular dementia(VaD). Its benefit in preventing further cognitive decline in patients with acute ischemic stroke(AIS) and vascular mild cognitive impairment(VaMCI) remains to be established. In this multicenter, double-blind trial, we randomly assigned 654 eligible patients to nimodipine 30 mg three times a day or placebo. The primary outcome was any cognitive decline defined by the changes on the Mini-Mental State Examination(DMMSE à3) or vascular AD assessment scale cognitive subscale(DADAS-cog ! 4) at 6 months. Secondary outcomes included any distribution shift of DADAS-cog, DMMSE or cognitive improvement defined by DADAS-cog à2, or DMMSE ! 0. The primary outcome in the nimodipine group and placebo group were similar for DMMSE à3(4.18% and 7.22%, respectively, P = 0.15) and DADAS-cog ! 4(8.36% and 8.93% respectively,P = 0.88). The distribution shift of DADAS-cog and DMMSE differed significantly between the two groups(P = 0.03 and P = 0.05 respectively). Cognitive improvement occurred in 55.4% in the nimodipine group and 43.6% in the placebo group measured by DADAS-cog à2(Odds Ratio, 1.54; 95% confidence interval[CI] 1.10–2.14, P < 0.01) or 84.0% and 74.6% respectively by DMMSE ! 0(Odds Ratio, 1.79; 95% CI 1.18–2.70, P < 0.01). Nimodipine was associated with better cognitive function in the memory domain. The adverse events rate was similar in two groups. This study is registered with ClinicalTrials.gov,NCT01220622. Nimodipine did not show benefit to prevent cognitive decline in AIS patients with VaMCI, but improved cognition moderately, especially measured in the memory domain. | Huaguang Zheng Yilong Wang Anxin Wang Hao Li David Wang Xingquan Zhao Penglian Wang Haipeng Shen Lijun Zuo Yuesong Pan Zixiao Li Xia Meng Xianwei Wang Weixiong Shi Yi Ju Liping Liu Kehui Dong Chunxue Wang Rubo Sui Rong Xue Xiaoping Pan Xiaoyua Niu Benyan Luo Yi Sui Huali Wang Tao Feng Yongjun Wang | 2019 | Science Bulletin2019,64,2: | 5 |
| 5 | Impairment of cognition and sleep after acute ischaemic stroke or transient ischaemic attack in Chinese patients: design, rationale and baseline patient characteristics of a nationwide multicentre prospective registry显示文摘background and aim Cognitive impairment and sleep disorder are both common poststroke conditions and are closely related to the prognosis of patients who had a stroke.The Impairment of CognitiON and Sleep after acute ischemic stroke or transient ischemic attack in Chinese patients(ICONS)study is a nationwide multicentre prospective registry to investigate the occurrence and associated factors of cognitive impairment and sleep disorder after acute ischaemic stroke(AIS)or transient ischaemic attack(TIA).Methods Consecutive AIS or TIA in-hospital patients within 7 days after onset were enrolled from 40 participating sites in China.Comprehensive baseline clinical and imaging data were collected prospectively.Blood and urine samples were also collected on admission and follow-up visits.Patients were interviewed face to face for cognition and sleep related outcomes at 2 weeks,3,6 and 12 months after AIS/TIA and followed up for clinical outcomes by telephone annually over 5 years.results Between August 2015 and January 2018,a total of 2625 patients were enrolled.92.65% patients had AIS and 7.35% patients had TIA.Overall,the average age was 61.04 years,and 72.38% patients were male.Median National Institutes of Health Stroke Scale score was 3 in AIS patients.Conclusions The ICONS study is a large-scale nationwide prospective registry to investigate occurrence and the longitudinal changes of cognitive impairment and sleep disorder after AIS or TIA.Data from this registry may also provide opportunity to evaluate associated factors of cognitive impairment or sleep disorder after AIS or TIA and their impact on clinical outcome. | Yongjun Wang Xiaoling Liao Chunxue Wang Ning Zhang Lijun Zuo Yang Yang Yuesong Pan Xianglong Xiang Jing Jing Xia Meng Xingquan Zhao Yilong Wang Jiong Shi Hao Li | 2021 | Stroke & Vascular Neurology2021,6,1: | 4 |
| 6 | Extraction of Basic Trends of Urban Expansion in China over Past 40 Years from Satellite Images显示文摘If urban sprawl is to be avoided in China in the next ten years, it is not only crucial to understand the overall history, current status, and future trends of urban expansion there, but also these differences, and this is presently lacking. In this study, remotely sensed images with approximately 30 m spatial resolution were used to quantitatively assess the spatial and temporal patterns of urban expansion of 60 Chinese cities(1973–2013). Urban-expansion-process curves of the cities studied were drawn using annual expansion area as an indicator. Curve similarity analysis generated four basic process modes of urban expansion in China. These included cities that: 1) peaked around 2004 and then decelerated; 2) peaked around 2010 and then decelerated; 3) showed sustained acceleration, and 4) showed continued deceleration. Four basic process modes represented cities under different levels of development stage. Geographic location was found to be the most related characteristic to urban expansion process. Regional development policies at the national level in each region also showed highly temporal consistency with fluctuation characteristics of urban expansion process. Urban characteristic such as population size and administrative level were not found to be significantly related to urban expansion-process modes. Understanding the basic process-mode categories well is extremely important for future regional-balance planning and development of macroeconomic policies. | WEN Qingke ZHANG Zengxiang SHI Lifeng ZHAO Xiaoli LIU Fang XU Jinyong YI Ling LIU Bin WANG Xiao ZUO Lijun HU Shunguang LI Na LI Minmin | 2016 | Chinese Geographical Science2016,26,2: | 4 |
| 7 | City Size Distribution and Its Spatiotemporal Evolution in China显示文摘Based on the National Land Use/Cover Database of China(NLUD-C) in the end of the 1980s(the 1980s,hereafter), 1995, 2000, 2005, and 2010, 665 cities were selected to study the size distribution and its changes of urban lands in China. In this study, the spatiotemporal evolutions of urban land size distribution as well as the influence of administrative-level on these cities were explored by combining urban spatial positions and administrative-levels. Results indicate that: 1) City size distribution using urban lands was more practical and reasonable than using non-agricultural population. 2) In the 1980s, cities with ascending urban land rank were centralized in Eastern China, specially the Changjiang(Yangtze) River Delta, the Zhujiang(Pearl) River Delta, and Beijing-Tianjin-Hebei region. Cities in Central, Western, and Northeast China mainly indicated descending urban land rank. 3) The transfer of national development focus resulted in cities with ascending urban land rank becoming evenly distributed nationwide; however, this trend was slightly centralized around Chengdu, Chongqing, and Wuhan in different periods. 4) During the 1980s to 2010, the proportion of cities with ascending urban land rank in provincial capitals, municipalities, and special administrative regions(high-level cities, hereafter) was consistently higher than those in prefecture- and county-level cities except for 2005–2010. The ranks of the majority of the prefecture- and county-level cities were mainly descending, supported by ascending; the proportion of cities with unchanged rank is small. This study breaks through the bottleneck of traditional research in the area of city size distribution by examining urban land replacing the non-agricultural population. The current study also provides scientific explanation for the healthy and reasonable development of urban land as well as the coordinated development of population urbanization and land urbanization. | SHI Lifeng ZHANG Zengxiang LIU Fang ZHAO Xiaoli WANG Xiao LIU Bin HU Shunguang WEN Qingke ZUO Lijun YI Ling XU Jinyong | 2016 | Chinese Geographical Science2016,26,6: | 4 |

| 9 | SHP2 regulates skeletal cell fate by modifying SOX9 expression and transcriptional activity显示文摘Chondrocytes and osteoblasts differentiate from a common mesenchymal precursor, the osteochondroprogenitor(OCP), and help build the vertebrate skeleton. The signaling pathways that control lineage commitment for OCPs are incompletely understood. We asked whether the ubiquitously expressed protein-tyrosine phosphatase SHP2(encoded by Ptpn11) affects skeletal lineage commitment by conditionally deleting Ptpn11 in mouse limb and head mesenchyme using 'Cre-lox P'-mediated gene excision.SHP2-deficient mice have increased cartilage mass and deficient ossification, suggesting that SHP2-deficient OCPs become chondrocytes and not osteoblasts. Consistent with these observations, the expression of the master chondrogenic transcription factor SOX9 and its target genes Acan, Col2a1, and Col10a1 were increased in SHP2-deficient chondrocytes, as revealed by gene expression arrays, q RT-PCR, in situ hybridization, and immunostaining. Mechanistic studies demonstrate that SHP2 regulates OCP fate determination via the phosphorylation and SUMOylation of SOX9, mediated at least in part via the PKA signaling pathway. Our data indicate that SHP2 is critical for skeletal cell lineage differentiation and could thus be a pharmacologic target for bone and cartilage regeneration. | Chunlin Zuo Lijun Wang Raghavendra M.Kamalesh Margot E.Bowen Douglas C.Moore Mark S.Dooner Anthony M.Reginato Qian Wu Christoph Schorl Yueming Song Matthew L.Warman Benjamin G.Neel Michael G.Ehrlich Wentian Yang | 2018 | Bone Research2018,6,2: | 3 |
| 10 | CsPb(I_(x)Br_(1-x))_(3) solar cells显示文摘Owing to its nice performance, low cost, and simple solution-processing, organic-inorganic hybrid perovskite solar cell(PSC) becomes a promising candidate for next-generation high-efficiency solar cells.The power conversion efficiency(PCE) has boosted from 3.8% to 25.2% over the past ten years. Despite the rapid progress in PCE, the device stability is a key issue that impedes the commercialization of PSCs. Recently, all-inorganic cesium lead halide perovskites have attracted much attention due to their better stability compared with their organic-inorganic counterpart. In this progress report, we summarize the properties of CsPb(IxBr1-x)3 and their applications in solar cells. The current challenges and corresponding solutions are discussed. Finally, we share our perspectives on CsPb(IxBr1-x)3 solar cells and outline possible directions to further improve the device performance. | Xue Jia Chuantian Zuo Shuxia Tao Kuan Sun Yixin Zhao Shangfeng Yang Ming Cheng Mingkui Wang Yongbo Yuan Junliang Yang Feng Gao Guichuan Xing Zhanhua Wei Lijun Zhang Hin-Lap Yip Mingzhen Liu Qing Shen Longwei Yin Liyuan Han Shengzhong Liu Lianzhou Wang Jingshan Luo Hairen Tan Zhiwen Jin Liming Ding | 2019 | Science Bulletin2019,64,20: | 2 |
| 11 | Urban Expansion of China from the 1970s to 2020 Based on Remote Sensing Technology显示文摘Based on Remote Sensing (RS) and Geographical Information System (GIS) technology,urban expansion of 75 cities in China from the 1970s to 2020 was reconstructed by visual-interpretation method,which described the growing process of urban lands and its influences on local land use structures synchronously.By employing annual expansion area per city and urban expansion density,spatial-temporal characteristics and macro patterns of urban expansion were analyzed from the aspects of regional-distributions,administrative-levels and population-sizes comprehensively.Results indicate that:1) urban expansion in China was universal,distinct,persistent,periodic and fluctuating.In the past five decades,urban lands of 75 monitored cities in China expanded dramatically from 3606.26 km2 to 30 521.13 km2.2) Though urban expansion presented significant differences from the aspects of regional distribution,administrative levels,and population sizes,it exhibited a deceleration trend in the 13th Five-Year Plan among all kinds of cities.3) Cultivated lands were the first land resource for urban expansion,and 55.17% of newly-expanded urban lands appeared by encroaching this land use type.China’s urban expansion has caused sustained pressure on cultivated land protection,especially in super megacities,and the contradiction between urban expansion and cultivated land protection will always exist.4) The compactness of urban lands in China increased before 1987 and reduced in the next three decades,which was consistent with the implementation of major policies and the deployment of national strategies,and is expected to become compact with a stopping declining or even rebounding after the 13th Five-Year Plan. | LIU Fang ZHANG Zengxiang ZHAO Xiaoli LIU Bin WANG Xiao YI Ling ZUO Lijun XU Jinyong HU Shunguang SUN Feifei WANG Yafei | 2021 | Chinese Geographical Science2021,31,5: | 2 |
| 12 | Preparation and hydrogen sorption properties of Mg-Cu-Y-H systems显示文摘Mg-xwt.%CuY (x=15, 20, 25) composites were successfully prepared by reactive mechanical alloying (RMA). X-ray diffraction (XRD) measurement shows that main phases of the as milled composites are MgH2 and Mg2Cu, and they converted into Mg and MgCu2 after dehydrogenation, respectively. Pressure-Composition-Isotherm (PCI) test shows that the composites exhibit double pressure plateau at each isothermal desorption process. The hydrogen absorption and desorption kinetics of the composites become worse with increasing x content, indicating that Mg-Cu phase has a negative effect on the hydrogen sorption properties of the composites. It is supposed that the good hydrogen sorption properties of the composites attribute to the catalyst effect of yttrium hydride distributed in Mg substrate and the particles size reduction and crystal defects formed by RMA. | LI Zhinian LIU Xiaopeng HUANG Zuo JIANG Lijun WANG Shumao | 2006 | Rare Metals2006,25,z2: | 1 |

| 14 | Hydrogen sorption properties of Mg-20wt.%Fe_(23)Y_8 composite prepared by reactive mechanical alloying显示文摘Mg-20wt.%Fe23Y8 composite was successfully prepared by reactive mechanical alloying (RMA). X-ray diffraction (XRD) measurement shows that the main phases of composite are MgH2 and Mg2FeH6. The composite exhibits excellent hydrogen abs/desorption properties and can absorb 4.36wt.% and 5.72wt.% hydrogen at 473 and 573 K in 10 min under 3.0 MPa hydrogen pressure, respectively. The composite can desorb 5.27wt.% hydrogen at 573 K in 30 min under 0.02 MPa hydrogen pressure. Compared with the pure MgH2, the hydrogen desorption temperature of Mg-20wt.% Fe23Y8 composite is decreased about 40 ℃. It is supposed that both the catalyst effect of Fe-Y distributed in Mg substrate and the crystal defects play the main role in improving hydrogen sorption properties of Mg-20wt.% Fe23Y8 composite. | LI Zhinian LIU Xiaopeng HUANG Zuo JIANG Lijun WANG Shumao | 2006 | Rare Metals2006,25,z1: | 1 |

| 18 | Spatial Patterns of Irrigation Water Withdrawals in China and Implications for Water Saving显示文摘By considering numerical features, spatial variation, and spatial association, the spatial patterns of China's irrigation water withdrawals in 2001 and 2010 were explored at the regional, provincial, and prefectural scales. In addition, an overlay analysis was used to develop specific water-saving guidance for areas under different levels of water stress and with different degrees of irrigation water withdrawals. It was found that at the regional scale, irrigation water withdrawals were highest in the Middle-Lower Yangtze River region in both years, while at the provincial scale, the largest irrigation water withdrawals occurred in Xinjiang. During 2001–2010, the total of irrigation water withdrawals decreased; however, in the Northeast region, especially in Heilongjiang Province, it experienced a dramatic increase. The spatial variation was largest at the prefectural scale, with an apparent effect. The spatial association was globally negative at the provincial scale, and Xinjiang was the only significant high-low outlier. In contrast, the association displayed a significant positive relationship at the prefectural scale, and several clusters and outliers were detected. Finally, it was found that the water stress in the northern part of China worsened and water-saving irrigation techniques urgently need to be applied in the Northeast region, the Huang-Huai-Hai Plain region, and Gansu-Xinjiang region. This study verified that a multi-scale and aspect analysis of the spatial patterns of irrigation water withdrawals were essential and provided water-saving advice for different areas. | JU Hongrun ZHANG Zengxiang WEN Qingke WANG Jiao ZHONG Lijin ZUO Lijun | 2017 | Chinese Geographical Science2017,27,3: | 0 |
