| 1 | Biomass carbon stocks in China's forests between 2000 and 2050:A prediction based on forest biomass-age relationships显示文摘China's forests are characterized by young forest age,low carbon density and a large area of planted forests,and thus have high potential to act as carbon sinks in the future.Using China's national forest inventory data during 1994-1998 and 1999-2003,and direct field measurements,we investigated the relationships between forest biomass density and forest age for 36 major forest types.Statistical approaches and the predicted future forest area from the national forestry development plan were applied to estimate the potential of forest biomass carbon storage in China during 2000-2050.Under an assumption of continuous natural forest growth,China's existing forest biomass carbon(C) stock would increase from 5.86 Pg C(1 Pg=1015 g) in 1999-2003 to 10.23 Pg C in 2050,resulting in a total increase of 4.37 Pg C.Newly planted forests through afforestation and reforestation will sequestrate an additional 2.86 Pg C in biomass.Overall,China's forests will potentially act as a carbon sink for 7.23 Pg C during the period 2000-2050,with an average carbon sink of 0.14 Pg C yr-1.This suggests that China's forests will be a significant carbon sink in the next 50 years. | XU Bing,GUO ZhaoDi,PIAO ShiLong & FANG JingYun* Department of Ecology,College of Urban and Environmental Sciences,and Key Laboratory for Earth Surface Processes of the Ministry of Education,Peking University,Beijing 100871,China | 2010 | Science China(Life Sciences)2010,53,7: | 61 |
| 2 | Patterns of above-and belowground biomass allocation in China's grasslands:Evidence from individual-level observations显示文摘Above-and belowground biomass allocation not only influences growth of individual plants,but also influences vegetation structures and functions,and consequently impacts soil carbon input as well as terrestrial ecosystem carbon cycling.However,due to sampling difficulties,a considerable amount of uncertainty remains about the root:shoot ratio(R/S),a key parameter for models of terrestrial ecosystem carbon cycling.We investigated biomass allocation patterns across a broad spatial scale.We collected data on individual plant biomass and systematically sampled along a transect across the temperate grasslands in Inner Mongolia as well as in the alpine grasslands on the Tibetan Plateau.Our results indicated that the median of R/S for herbaceous species was 0.78 in China's grasslands as a whole.R/S was significantly higher in temperate grasslands than in alpine grasslands(0.84 vs.0.65).The slope of the allometric relationship between above-and belowground biomass was steeper for temperate grasslands than for alpine.Our results did not support the hypothesis that aboveground biomass scales isometrically with belowground biomass.The R/S in China's grasslands was not significantly correlated with mean annual temperature(MAT) or mean annual precipitation(MAP).Moreover,comparisons of our results with previous findings indicated a large difference between R/S data from individual plants and communities.This might be mainly caused by the underestimation of R/S at the individual level as a result of an inevitable loss of fine roots and the overestimation of R/S in community-level surveys due to grazing and difficulties in identifying dead roots.Our findings suggest that root biomass in grasslands tended to have been overestimated in previous reports of R/S. | WANG Liang*,NIU KeChang,YANG YuanHe & ZHOU Peng Department of Ecology,Key Laboratory for Earth Surface Processes of the Ministry of Education,Peking University,Beijing 100871,China. | 2010 | Science China(Life Sciences)2010,53,7: | 54 |
| 3 | Quantitative relationship between pollen and vegetation in northern China显示文摘205 surface pollen samples from different communities in Northern China were analyzed to understand the quantitative relationship between pollen and its original vegetation. Pollen analysis and vegetation investigation show that the pollen assemblages differ a lot in different vegetation regions. Arboreal pollen account for more than 30% in temperate broad-deciduous forests region. In temperate steppe regions, herb pollen percentages are more than 90%, where Artemisia and Chenopodiaceae are domi- nant pollen types with Artemisia percentages more than 30%. In temperate desert, Chenopodiaceae pollen percentages are more than Artemisia, where ferns are rare. Cyperaceae pollen percentages are more than 20% in sub-alpine or cold meadows. The relations between pollen percentages and vegeta- tion cover indicate that most arboreal pollen shows a close relationship with parent plant covers, most shrubby pollen types have more or less correlations, but most herbs do not show clear correlations. For arboreal pollen types, Picea pollen shows the closest correlation with spruce trees coverage, then is Quercus and Carpinus. Betula, Larix and Juglans have also high correlation coefficients with their plants coverage, but Betula pollen is of overrepresented pollen type and more than 40% in birch forest, while Larix and Juglans pollen is underrepresented and pollen percentages are more than 10% in Larix or Juglans pure forests. Pinus is of overrepresented pollen type, and pollen percentages have some relations with plants cover. Pine forest might present when Pinus pollen percentages are more than 30%. The relations between Ulmus and Populus pollen percentages and vegetation cover are not close, where they are mixed with other arbors, they cannot be recorded easily, but if their pollen percentages are more than 1%, Ulmus or Populus trees should exist. For shrubby pollen types, the correlation be- tween Vitex pollen percentages and vegetation cover is the highest, then is Corylus, Tamariaceae and Nitraria, and their pollen percentages are less than 1% where original plant are absent. Caragana and Spiraea pollen percentages have some relations with vegetation cover. The relations between pollen percentages and vegetation cover are not clear for Rosaceae and Saxifragaceae. For herb pollen types, Cyperaceae pollen has the closest correlation with vegetation cover, where pollen percentages are more than 20% when Cyperaceae are constructive or dominant species in vegetation, and pollen per- centages are less than 5% where Cyperaceae are not constructive or dominant species (cover less than 30%). Artemisia and Chenopodiaceae pollen percentages mainly have close relations with ecological regions. The relations between pollen percentages and cover are not clear for Gramineae, Legumi- nosae and Compositae. | XU QingHai LI YueCong YANG XiaoLan ZHENG ZhenHua | 2007 | Science China Earth Sciences2007,50,4: | 41 |

| 7 | QSAR Studies on the Inhibitory Activityof Levofloxacin-thiadiazole HDACi Conjugates to Histone Deacetylases显示文摘A molecular electronegativity distance vector(M_t)based on 13 atomic types has been used to describe the structures of 19 conjugates(LHCc)of levofloxacin-thiadiazole HDAC inhibitor(HDACi)and related inhibitory activities(pH_i,i=1,2,6)of LHCc against histone deacetylases(HDACs,such as HDAC1,HDAC2 and HDAC6).The quantitative structure-activity relationships(QSAR)were established by using leaps-and-bounds regression analysis for the inhibitory activities(pH_i)of 19 above compounds to HDAC1,HDAC2 and HDAC6 along with M_t.The correlation coefficients(R^2)and the leave-one-out(LOO)cross validation R_(cv)^(2 )for the pH_1,pH_(2 )and pH_(6 )models were 0.976 and 0.949;0.985 and 0.977;0.976 and 0.932,respectively.The QSAR models had favorable correlations,as well as robustness and good prediction capability by R^2,F,R^2_(cv),A_(IC),F_(IT )and V_(IF )tests.Validated by using 3876 training sets,the models have good external prediction ability.The results indicate that the molecular structural units:–CH_g–(g=1,2),–NH_2,–OH,=O,–O–and–S–are the main factors which can affect the inhibitory activity of pH_1,pH_(2 )as well as pH_(6 )bioactivities of these compounds directly.Accordingly,the main interactions between HDACs inhibitor and HDACs are hydrophobic interaction,hydrogen bond,and coordination with Zn^(2+)to form compounds,which is consistent with the results in reports. | 王超 冯长君 | 2018 | Chinese Journal of Structural Chemistry2018,37,11: | 23 |
| 8 | Genome-wide analysis of the WRKY transcription factor gene family in Gossypium raimondii and the expression of orthologs in cultivated tetraploid cotton显示文摘WRKY proteins are members of a family of transcription factors in higher plants that function in plant responses to various physiological processes.We identified 120 candidate WRKY genes from Gossypium raimondii with corresponding expressed sequence tags in at least one of four cotton species,Gossypium hirsutum,Gossypium barbadense,Gossypium arboreum,and G.raimondii.These WRKY members were anchored on 13 chromosomes in G.raimondii with uneven distribution.Phylogenetic analysis showed that WRKY candidate genes can be classified into three groups,with 20 members in group I,88 in group II,and 12 in group III.The88 genes in group II were further classified into five subgroups,groups IIa–e,containing 7,16,37,15,and 13 members,respectively.We characterized diversity in amino acid residues in the WRKY domain and/or other zinc finger motif regions in the WRKY proteins.The expression patterns of WRKY genes revealed their important roles in diverse functions in cotton developmental stages of vegetative and reproductive growth and stress response.Structural and expression analyses show that WRKY proteins are a class of important regulators of growth and development and play key roles in response to stresses in cotton. | Caiping Cai Erli Niu Hao Du Liang Zhao Yue Feng Wangzhen Guo | 2014 | The Crop Journal2014,2,Z1: | 23 |

| 10 | Single-atom catalyst: a rising star for green synthesis of fine chemicals显示文摘The green synthesis of fine chemicals calls for a new generation of efficient and robust catalysts. Single-atom catalysts(SACs), in which all metal species are atomically dispersed on a solid support, and which often consist of well-defined mononuclear active sites, are expected to bridge homogeneous and heterogeneous catalysts for liquid-phase organic transformations. This review summarizes major advances in the SAC-catalysed green synthesis of fine chemicals in the past several years, with a focus on the catalytic activity, selectivity and reusability of SACs in various organic reactions. The relationship between catalytic performance and the active site structure is discussed in terms of the valence state, coordination environment and anchoring chemistry of single atoms to the support, in an effort to guide the rational design of SACs in this special area, which has traditionally been dominated by homogeneous catalysis.Finally, the challenges remaining in this research area are discussed and possible future research directions are proposed. | Leilei Zhang Yujing Ren Wengang Liu Aiqin Wang Tao Zhang | 2018 | National Science Review2018,5,5: | 15 |
| 11 | Impact of hillslope vegetation restoration on gully erosion induced sediment yield显示文摘Facing the eco-environmental construction on the Loess Plateau, especially the vegeta-tion restoration in the semiarid areas, as well as the dam system engineering construction that is about to start, how can the vegetation restoration gain the optimum ecological benefits following the improvement of the preservation rates of trees and grass on the basis of guaranteeing water storage and silt trapping effects? What techniques should be taken to restore vegetation? These questions critical to environmental management on the Loess Plateau have to be settled urgently. According to the different macroscopic spatial distribution patterns of forest and grass on the Loess Plateau, this paper analyzes the macroscopic hillslope and gully management relationship in the middle Yellow River and weight of natural and human factors in erosion-induced sediment yield in the context of environmental background of the major silt producing areas. In light of the current status of the inte-grated management of small watersheds and soil and water conservation measure arrangement schemes of hillslopes and gullies on the Loess Plateau, this paper discusses the impact of vegetation restoration on gully erosion induced sediment yield and the effect of vegetation caused sediment re-duction. Studies indicate that there exists an erosional environmental background related to the natural and human activities in the sediment yield peak values of the sandy and coarse sandy areas in the middle Yellow River, sediment yield modulus is closely related to the synthetic effect of environ-mental elements, and the rainstorms, reclamation rate and forest coverage are the main factors af-fecting sediment yield modulus in the sandy and coarse sandy areas. The key to control soil erosion in the sandy and coarse sandy areas is the conversion of farmland into forestland and grassland, the reduction of reclamation rate and the increase of tree and grass vegetation. Small catchment man-agement should adhere to the principle of simultaneous control of hillslope and gully erosion and combination of biological measures with engineering measures. Engineering measures play an im-portant role in the hillslope vegetation restoration in the initial period. Vegetation restoration can result in a reduction of erosion induced sediment yield in gullies of Yangjiagou by over 75%. | CHEN Hao CAI Qiangguo | 2006 | Science China Earth Sciences2006,49,2: | 13 |
| 12 | A decision-making model of development intensity based on similarity relationship between land attributes intervened by urban design显示文摘The paper presents a dynamic model intervened by urban design for the decision-making of land development intensity, which expresses the inherent interaction mechanism between lands based on the evaluation of land attributes and their similarity relationship. Each land unit is described with several factors according to their condition and potential for development, such as land function, accessibility, historical site control, landscape control, and so on. Then, the dynamic reference relationship between land units is established according to the similarity relationship between their factors. That means lands with similar conditions tend to have similar development intensities, which expresses the rule of the spontaneous urban development. Therefore, the development intensities of the pending lands can be calculated by the confirmed ones. Furthermore, the system can be actively intervened by adjusting the parameters according to urban design or planning intentions. And the reaction of the system offers effective support and reference for reasonable decision. The system with multiple intervention input is not only a credible tool for deriving development intensities, but also a platform to activate urban design conception. Above all, the system as a socio-technical tool integrates the optimization of form, function and environment, and embodies the principle of impersonality, justice and flexibility in the decision of land development intensity. | WANG JianGuo1, ZHANG Yu2 & FENG Han3 1 School of Architecture, Southeast University Key Laboratory for Urban and Architectural Heritage Conservation, Ministry of Education, Nanjing 210096, China 2 School of Architecture, Southeast University, Nanjing 210096, China 3 Faculty of Architecture, Delft University of Technology, 2628 CR Delft, Netherlands | 2010 | Science China(Technological Sciences)2010,53,7: | 12 |
| 13 | Effect of cooling rate during quenching on the microstructure and creep property of nickel-based superalloy FGH96显示文摘The effect of cooling rate during quenching on the microstructure and creep property of nickel-based superalloy FGH96 was investigated. Three groups of samples were quenched continuously with three fixed cooling rates, respectively, then subjected to a creep test under a constant load of 690 MPa at 700℃. Clear differences in size of secondary γ′ precipitates, creep properties and substructure of creep-tested samples were observed. The quantitative relationship among cooling rate, the size of secondary γ′ precipitates, and steady creep rate was constructed. It was found that with increasing cooling rate, the size of secondary γ′ precipitates decreases gradually, showing that the relationship between the size of secondary γ′ precipitates and the cooling rate obeys a power law, with an exponent of about –0.6, and the creep rate of steady state follows a good parabola relationship with cooling γ′ precipitate size. For 235℃/min, FGH96 alloy exhibited very small steady creep rate. The density of dislocation was low, and the isolated stacking fault was the dominant deformation mechanism. With decreasing cooling rates, the density of dislocation increased remarkably, and deformation microtwinning was the dominant deformation process. Detailed mechanisms for different cooling rate were discussed. | Ye-fei Feng Xiao-ming Zhou Jin-wen Zou Gao-feng Tian | 2019 | International Journal of Minerals,Metallurgy and Materials2019,26,4: | 11 |
| 14 | Gut-lung crosstalk in pulmonary involvement with inflammatory bowel diseases显示文摘Pulmonary abnormalities,dysfunction or hyper-reactivity occurs in association with inflammatory bowel disease(IBD) more frequently than previously recognized.Emerging evidence suggests that subtle inflammation exists in the airways among IBD patients even in the absence of any bronchopulmonary symptoms,and with normal pulmonary functions. The pulmonary impairment is more pronounced in IBD patients with active disease than in those in remission. A growing number of case reports show that the IBD patients develop rapidly progressive respiratory symptoms after colectomy,with failure to isolate bacterial pathogens on repeated sputum culture,and often request oral corticosteroid therapy. All the above evidence indicates that the inflammatory changes in both the intestine and lung during IBD. Clinical or subclinical pulmonary inflammation accompanies the main inflammation of the bowel.Although there are clinical and epidemiological reports of chronic inflammation of the pulmonary and intestinal mucosa in IBD,the detailed mechanisms of pulmonaryintestinal crosstalk remain unknown. The lung has no anatomical connection with the main inflammatory site of the bowel. Why does the inflammatory process shift from the gastrointestinal tract to the airways? The clinical and subclinical pulmonary abnormalities,dysfunction,or hyper-reactivity among IBD patients need further evaluation. Here,we give an overview of the concordance between chronic inflammatory reactions in the airways and the gastrointestinal tract. A better understanding of the possible mechanism of the crosstalk among the distant organs will be beneficial in identifying therapeutic strategies for mucosal inflammatory diseases such as IBD and allergy. | Hui Wang Jing-Shi Liu Shao-Hua Peng Xi-Yun Deng De-Mao Zhu Sara Javidiparsijani Gui-Rong Wang Dai-Qiang Li Long-Xuan Li Yi-Chun Wang Jun-Ming Luo | 2013 | World Journal of Gastroenterology2013,19,40: | 11 |
| 15 | Estimation of annual actual evapotranspiration from nonsaturated land surfaces with conventional meteorological data显示文摘Views diverge greatly on the relationship between actual evapotranspiration (AE) and potential evapotranspiration (PE). Penman showed that AE is determined in intensity by PE and changes proportionally as a function of PE. In contrast, Bouchet indicated that AE deter-mines PE and varies inversely with PE. Based on nearly 30 years data from 432 weather stations and 512 hydrological stations in China, the two different theories, Penman抯 assumption and Bouchet抯 complementary relationship between AE and PE, were tested on nine river basins. With data integration technique, the complementary relationship between AE and PE was dis-played entirely. A general model to estimate the actual evapotranspiration from nonsaturated surfaces by routine meteorological observations has been established on the basis of thorough analysis of the concept of PE. The results show that the calculations are all in error control of <10%, except for a few years over the Yellow River Basin. | QIU Xinfa1, ZENG Yan2, MIAO Qilong1 & YU Qiang2 1.

| 17 | Fabrication of NiFe layered double hydroxide with well-defined laminar superstructure as highly efficient oxygen evolution electrocatalysts显示文摘Structure-activity relationship (SAR) is the key problem of nanoscience,thus to fabricate novel and well-defined nanostructure will provide a new insight on catalyst preparation method.Highly active and low cost electrocatalysts for oxygen evolution reaction (OER) are of great importance for future renewable energy conversion and storage.Herein,NiFe-based layered double hydroxides with laminar structure (NFLS) were successfully fabricated via a one-step hydrothermal approach by using sodium dodecyl sulfate as surfactant.The as-fabricated NFLS showed a well-defined periodic layered-stacking geometry with a scale down to 1-nm.Benefitting from the unique structure,NFLS exhibited an excellent catalytic activity towards OER with current densities of 10 mA·cm^-2 at overpotential of 197 mV.The synergistic effect of Ni and Fe plays a key role in electrode reactions.The present work provides a new insight to improve the OER performance by rational design of electrocatalysts with unique structures. | Hao Zhang Haoyi Li Bilal Akram Xun Wang | 2019 | Nano Research2019,12,6: | 10 |

| 19 | 中国人地关系评价的理论模型与实证(英文)显示文摘China’s coupled human-environment system(CHES) is assessed here via a systems schema that emphasizes the complex interactions of components and their attributes. In addition to the human and environment components, we identified two other components to evaluate the relationship. The four components are human activity intensity, resource carrying capacity, ecological constraints and system’s openness. Based on their interactions, we derived a cognitive schema for classifying the level of strain or stress of an area. The analysis draws on 11 indicators and 29 sub-indicators including remote sensing data and statistical data that are used to estimate the four components. The findings indicate that human activities are highly intense in a few geographical areas, particularly large urban systems and trade and investment zones on the eastern coastal areas. Nonetheless, these areas are also well-endowed in water resources and fertile soils although urban systems are increasingly stressed from negative pollution externalities. They are also open systems which allow them to bear a higher level of pressure and adjust accordingly. Desertification and soil erosion point to relatively fragile biophysical systems in the west and southwest, but human activities are still relatively less intense compared to their coastal counterparts. As a whole, only 14% of areas may be said to be relatively or highly strained. This however belies another one-third of areas that are currently unstable, and likely to become strained and thereby vulnerable in the near future. | 杨宇 李小云 董雯 POON PH Jessie 洪辉 何则 刘毅 | 2019 | Journal of Geographical Sciences2019,29,8: | 9 |
| 20 | A review of extractive distillation from an azeotropic phenomenon for dynamic control显示文摘Extractive distillation is an effective method for separating azeotropic or close boiling point mixtures by adding a third component.Various technologies for performing the extractive distillation process have been explored to protect the environment and save resources.This paper focuses on the improvement of these advanced technologies in recent years.Extractive distillation is retrieved and analyzed from the view of phase equilibrium,selection of solvent in extractive distillation,process design,energy conservation,and dynamic control.The quantitative structure–property relationship used in extractive distillation is discussed,and the future development of extractive distillation is proposed to determine how the solvent affects the relative volatility of the separated mixture.In the steady state design,the relationship between the curvature of the residue curve and parameters of the optimal steady state is also highlighted as another field worthy of further study to simplify the distillation process. | Yixin Ma Peizhe Cui Yongkun Wang Zhaoyou Zhu Yinglong Wang Jun Gao | 2019 | Chinese Journal of Chemical Engineering2019,27,7: | 9 |
