| 1 | Carbon storage in evergreen broad-leaf forests in mid-subtropical region of China at four succession stages显示文摘To better understand the effect of forest succession on carbon sequestration, we investigated carbon stock and allocation of evergreen broadleaf forest, a major zonal forest in subtropical China.We sought to quantify the carbon sequestration potential.We sampled four forest types,shrub(SR), pine(Pinus massoniana) forest(PF), pine and broadleaf mixed forest(MF) and evergreen broadleaf forest(BF).A regression equation was constructed using tree height and diameter at breast height(DBH) and elements of total tree biomass.The equation was subsequently utilized to estimate tree carbon storage.The carbon storage of understory, litter, and soil was also estimated.Carbon storage in biomass increased significantly from the early succession stage SR(6.21 t ha-1) to the late stage BF(134.87 t ha-1).The biomass carbon stock of forest layers generally increased with succession except for the understory.The soil organic carbon storage for the total profile increased with forest succession, from 51.16 to 90.49 t ha-1, but the contribution of SOC to the carbon stock of the forest ecosystem declined from 89.18% to 40.15%.The carbon stock at ecosystem scale increased significantly with succession from SR(57.37 t ha-1), to PF(154.20 t ha-1), to MF(170.96 t ha-1)and to BF(225.36 t ha-1), with carbon stock of BF3.93 times that of SR.The forests in our study have great potential for increasing carbon sequestration, and large areas of secondary or degraded evergreen broadleaf forests in the subtropical zone of China could be a great carbon sink in future. | ZENG Zhangquan WANG Silong ZHANG Canming GONG Chao HU Qing | 2013 | Journal of Forestry Research2013，24，4： | 17 |
| 2 | Nitrogen Deposition and Its Spatial Pattern in Main Forest Ecosystems along North-South Transect of Eastern China显示文摘A continuous three-year observation(from May 2008 to April 2011)was conducted to characterize the spatial variation of dissolved inorganic nitrogen(DIN)deposition at eight main forest ecosystems along the north-south transect of eastern China(NSTEC).The results show that both throughfall DIN deposition and bulk DIN deposition increase from north to south along the NSTEC.Throughfall DIN deposition varies greatly from 2.7 kg N/(ha·yr)to 33.0 kg N/(ha·yr),with an average of 10.6 kg N/(ha·yr),and bulk DIN deposition ranges from 4.1 kg N/(ha·yr)to 25.4 kg N/(ha·yr),with an average of 9.8 kg N/(ha·yr).NH4+-N is the dominant form of DIN deposition at most sampling sites.Additionally,the spatial variation of DIN deposition is controlled mainly by precipitation.Moreover,in the northern part of the NSTEC,bulk DIN deposition is 17%higher than throughfall DIN deposition,whereas the trend is opposite in the southern part of the NSTEC.The results demonstrate that DIN deposition would likely threaten the forest ecosystems along the NSTEC,compared with the critical loads(CL)of N deposition,and DIN deposition in this region is mostly controlled by agricultural activities rather than industrial activities or transportation. | ZHAN Xiaoyun YU Guirui HE Nianpeng FANG Huajun JIA Bingrui ZHOU Mei WANG Chuankuan ZHANG Junhui ZHAO Guangdong WANG Silong LIU Yunfen YAN Junhua | 2014 | Chinese Geographical Science2014，24，2： | 10 |
| 3 | Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world. | Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong | 2022 | Science China(Life Sciences)2022，65，9： | 9 |
| 4 | Stability of soil organic carbon changes in successive rotations of Chinese fir(Cunninghamia lanceolata(Lamb.) Hook) plantations显示文摘The importance of soil organic carbon(SOC) under forests in the global carbon cycle depends on the stability of the soil carbon and its availability to soil microbial biomass.We investigated the effects of successive rotations of Chinese fir(Cunninghamia lanceolata(Lamb.) Hook) plantations on the stability of SOC and its availability to microbes by adopting the two-step hydrolysis with H2SO4 and density fractionation.The results showed that successive rotations of Chinese fir decreased the quantity of total SOC,recalcitrant fraction,and carbohydrates in Labile Pool I(LP Ⅰ),and microbial properties evidently,especially at 0-10 cm horizon.However,cellulose included in Labile Pool II(LP Ⅱ) and the cellulose/total carbohydrates ratio increased in successive rotations of Chinese fir.The non-cellulose of carbohydrates included in LP I maybe highly available to soil microbial biomass.Hence the availability of SOC to microbial biomass declined over the successive rotations.Although there was no significant change in recalcitrance of SOC over the successive rotations of Chinese fir,the percentage of heavy fraction to total SOC increased,suggesting that the degree of physical protection for SOC increased and SOC became more stable over the successive rotations.The degradation of SOC quality in successive rotation soils may be attributed to worse environmental conditions resulted from disturbance that related to 'slash and burn' site preparation.Being highly correlated with soil microbial properties,the cellulose/total carbohydrates ratio as an effective indicator of changes in availability of SOC to microbial biomass brought by management practices in forest soils. | ZHANG Jian WANG Silong FENG Zongwei WANG Qingkui | 2009 | Journal of Environmental Sciences2009，21，3： | 7 |
| 5 | Soil microbial activity and nutrients of evergreen broad-leaf forests in mid-subtropical region of China显示文摘To better understand the effects of forest succession on soil microbial activity, a comparison of soil microbial properties and nutrients was conducted between three forest types representing a natural forest succession chronosequence. The study compared a pine(Pinus massoniana) forest(P_F), a pine and broadleaf mixed forest(M_F) and an evergreen broadleaf forest(B_F), in the Yingzuijie Biosphere Reserve, Hunan Province, China.Results showed that soil nutrients in the M_Fand BFplots were higher than in the P_Fplots. The range in microbial biomass carbon followed a similar pattern with B_Fhaving the greatest values, 522–1022 mg kg^-1, followed by M_F368–569 mg kg^-1, and finally, P_F193–449 mg kg^-1. Soil nutrients were more strongly correlated with microbial biomass carbon than basal respiration or metabolic quotient. Overall, forest succession in the study site improved soil microbial properties and soil fertility, which in turn can increase primary productivity and carbon sequestration. | Zhangquan Zeng Silong Wang Canming Zhang Hong Tang Xiquan Li Zijian Wu Jia Luo | 2015 | Journal of Forestry Research2015，26，3： | 5 |

| 7 | Thermal behavior of an isolator with mode transition inducing back-pressure of a dual-mode scramjet显示文摘Combustion mode transition is a valuable and challenging research area in dual-mode scramjet engines.The thermal behavior of an isolator with mode transition inducing backpressure is investigated by direct-connect dual-mode scramjet experiments and theoretical analysis.Combustion experiments are conducted under the incoming airflow conditions of total temperature1270 K and Mach 2.A small increment of the fuel equivalence ratio is scheduled to trigger mode transition.Correspondingly,the variation of the coolant flow rate is very small.Based on the measured wall pressures,the heat-transfer model can quantify the thermal state variation of the engine with active cooling.Compared with the combustor,mode transition has a greater effect on the isolator thermal behavior,and it significantly changes the isolator heat-flux and wall temperature.To further study the isolator thermal behavior from flight Mach 4 to Mach 7,a theoretical analysis is carried out.Around the critical point of combustion mode transition,sudden changes of the isolator flowfield and thermal state are discussed. | Yang Qingchun Bao Wen Chetehouna Khaled Zhang Silong Gascoin Nicolas | 2017 | Chinese Journal of Aeronautics2017，30，2： | 2 |

| 9 | Two Ultraviolet Radiation Datasets that Cover China显示文摘Ultraviolet(UV) radiation has significant effects on ecosystems, environments, and human health, as well as atmospheric processes and climate change. Two ultraviolet radiation datasets are described in this paper. One contains hourly observations of UV radiation measured at 40 Chinese Ecosystem Research Network stations from 2005 to 2015. CUV3 broadband radiometers were used to observe the UV radiation, with an accuracy of 5%, which meets the World Meteorology Organization's measurement standards. The extremum method was used to control the quality of the measured datasets. The other dataset contains daily cumulative UV radiation estimates that were calculated using an all-sky estimation model combined with a hybrid model. The reconstructed daily UV radiation data span from 1961 to 2014. The mean absolute bias error and root-mean-square error are smaller than 30% at most stations, and most of the mean bias error values are negative, which indicates underestimation of the UV radiation intensity. These datasets can improve our basic knowledge of the spatial and temporal variations in UV radiation. Additionally, these datasets can be used in studies of potential ozone formation and atmospheric oxidation, as well as simulations of ecological processes. | Hui LIU Bo HU Yuesi WANG Guangren LIU Liqin TANG Dongsheng JI Yongfei BAI Weikai BAO Xin CHEN Yunming CHEN Weixin DING Xiaozeng HAN Fei HE Hui HUANG Zhenying HUANG Xinrong LI Yan LI Wenzhao LIU Luxiang LIN Zhu OUYANG Boqiang QIN Weijun SHEN Yanjun SHEN Hongxin SU Changchun SONG Bo SUN Song SUN Anzhi WANG Genxu WANG Huimin WANG Silong WANG Youshao WANG Wenxue WEI Ping XIE Zongqiang XIE Xiaoyuan YAN Fanjiang ZENG Fawei ZHANG Yangjian ZHANG Yiping ZHANG Chengyi ZHAO Wenzhi ZHAO Xueyong ZHAO Guoyi ZHOU Bo ZHU | 2017 | Advances in Atmospheric Sciences2017，34，7： | 2 |
| 10 | Thermodynamic analysis for a chemically recuperated scramjet显示文摘Endothermic hydrocarbon fuel is regarded as an optimal fuel for a scramjet with regenerative cooling,which provides extra cooling through endothermic chemical conversion to avoid the severly limited cooling capacity when conventional fuels are adopted for cooling.Although endothermic cooling is proposed from the view point that the heat sink of a conventional fuel is insufficient,the heat-absorbing through endothermic chemical reaction is actually a chemical recuperation process because the wasted heat dissipated from the engine thermal structure is recovered through the endothermic chemical reaction.Therefore,the working process of a scramjet with endothermic hydrocarbon fuel cooling is a chemical recuperative cycle.To analyze the chemical recuperative cycle of a chemically recuperated scramjet engine,we defined physical and chemical recuperation effectivenesses and heating value increment rate,and derived engine performance parameters with chemical recuperation.The heat value benefits from both physical and chemical recuperations,and it increases with the increase in recuperation effectiveness.The scramjet performance parameters also increase with the increase in chemical recuperation effectiveness.The increase in chemical recuperation effectiveness improves both the performances of the fuel cooling system and the combustion system.The results of analysis prove that the existence of a chemical recuperation process greatly improves the performance of the whole scramjet. | QIN Jiang BAO Wen ZHANG SiLong SONG YuFei YU DaRen | 2012 | Science China(Technological Sciences)2012，55，11： | 2 |

| 14 | Electronic characteristic,tensile cracking behavior and potential energy surface of TiC(111)/Ti(0001)interface:A first principles study显示文摘The preparation of TiC coating on Ti alloy surface to improve the wear resistance has attracted attention from researchers in aerospace field.The service life of TiC coating is related to the interfacial adhesion properties between TiC coating and Ti alloy substrate.However,it is difficult to explain its interfacial adhesion mechanism by experimental methods.Based on the termination of atoms on the TiC surface,two TiC/Ti interface models named as the C-terminated-TiC(111)/Ti(0001) and Ti-terminated-TiC(11)/Ti(0001) interface were constructed by first-principles.The interfacial electronic characteristic of C-Ti bond is a mixture of polar covalent and metal bonds,and that of Ti-Ti bond is the metal bond.The tensile strains of both C-terminated-TiC(111)/Ti(0001) and Ti-terminated-TiC(111)/Ti(0001) interface in the fracture stage are ranged from 12% to 14%.Their maximum tensile stresses are 16.201 GPa and 15.590GPa,respectively.The sliding potential energy surface maximum of C-terminated-TiC(111)/Ti(0001) and Ti-terminated-TiC(111)/Ti(0001) interface are 5.387 J/m^(2) and 0.271 J/m^(2),respectively.And the sliding potential barriers on the minimum energy path are 2.094 J/m2and 0.136 J/m^(2) with an ideal shear strength of 20.32 GPa and 1.61 GPa,respectively.In summary,the interfacial adhesion property of C-terminated-TiC(111)/Ti(0001) interface is better than that of Ti-terminated-TiC(111)/Ti(0001) interface. | Silong ZHANG Jibo WANG Lixiang RAO Qizhen HE Xiaolei XING Yefei ZHOU Qingxiang YANG | 2023 | Chinese Journal of Aeronautics2023，36，9： | 0 |
| 15 | Regulating ethane and ethylene synthesis by proton corridor microenvironment for CO_(2) electrolysis显示文摘Electrocatalytic reduction of carbon dioxide is one of the most effective strategies to achieve carbon neutrality and energy sustainability.Although high-value multi-carbon products have been widely studied,limited electrocatalysts have been reported for the selective conversion of ethane.More importantly,the factors tuning the selectivity between ethane and ethylene have not been clarified.Here,Zn@Cu nanowire arrays(Zn@Cu-NWAs) catalyst is proposed to stimulate the maintenance of efficient CO_(2)-to-C_(2)H_(6) conversion at high current densities.Meanwhile,in order to investigate the factors affecting the interconversion between ethane and ethylene,the counterpart catalyst that facilitates C–C coupling to ethylene was also synthesized.Time-of-flight secondary-ion mass spectroscopy(TOF-SIMS),in-situ Raman spectroscopy,and simulation results show that Zn@Cu-NWAs can provide a localized proton corridor environment for the formation of ethane,accelerating the further proton-coupled CO_(2) reduction reaction(CO_(2)RR)kinetics.Hence,this catalyst delivered an ethane Faraday efficiency of over 65% at-1.14 V vs.RHE with a total current density of 142.3 mA/cm^(2).This work provides a new perspective on regulating the local microenvironment to modify the selectivity of multi-carbon products. | Xiaowen Zhang Bohua Ren Hao Li Shuxuan Liu Haoyang Xiong Silong Dong Yifan Li Dan Luo Yi Cui Guobin Wen Xin Wang | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
| 16 | Allocation patterns of nonstructural carbohydrates in response to CO_(2)elevation and nitrogen deposition in Cunninghamia lanceolata saplings显示文摘Stored nonstructural carbohydrates(NSC)indicate a balance between photosynthetic carbon(C)assimilation and growth investment or loss through respiration and root exudation.They play an important role in plant function and whole-plant level C cycling.CO_(2)elevation and nitrogen(N)deposition,which are two major environmental issues worldwide,aff ect plant photosynthetic C assimilation and C release in forest ecosystems.However,information regarding the eff ect of CO_(2)elevation and N deposition on NSC storage in diff erent organs remains limited,especially regarding the trade-off between growth and NSC reserves.Therefore,here we analyzed the variations in the NSC storage in diff erent organs of Chinese fi r(Cunninghamia lanceolata)under CO_(2)elevation and N addition and found that NSC concentrations and contents in all organs of Chinese fi r saplings increased remarkably under CO_(2)elevation.However,N addition induced diff erential accumulation of NSC among various organs.Specifi cally,N addition decreased the NSC concentrations of needles,branches,stems,and fi ne roots,but increased the NSC contents of branches and coarse roots.The increase in the NSC contents of roots was more pronounced than that in the NSC content of aboveground organs under CO_(2)elevation.The role of N addition in the increase in the structural biomass of aboveground organs was greater than that in the increase in the structural biomass of roots.This result indicated that a diff erent tradeoff between growth and NSC storage occurred to alleviate resource limitations under CO_(2)elevation and N addition and highlights the importance of separating biomass into structural biomass and NSC reserves when investigating the eff ects of environmental change on biomass allocation. | Wenhui Zheng Renshan Li Qingpeng Yang Weidong Zhang Ke Huang Xin Guan Longchi Chen Xin Yu Qingkui Wang Silong Wang | 2023 | Journal of Forestry Research2023，34，1： | 0 |

| 18 | Metastable hybridized structure transformation in amorphous carbon films during friction-A study combining experiments and MD simulation显示文摘Amorphous carbon films have attracted substantial interest due to their exceptional mechanical and tribological properties.Previous studies revealed that the amorphous carbon films exhibited lower coefficient of friction(COF)because of the transformation in bond structure from sp^(3)-C to sp^(2)-C during friction processes.However,the mechanism for such a transformation during friction is not well understood.This study is conducted to get an insight into the metastable transformation in amorphous carbon film during friction by means of experiments and molecular dynamics(MD)simulation.Relevant wear tests showed that wear of the film changed from an abrasive wear mode to a mixture of abrasion and adhesive wear,resulting in a decrease in growth rate of the wear rate after the running-in stage.It is worth noting that the sp^(3)-C atoms were increased during the running-in stage when the films contained lower sp^(3)/sp^(2) ratios.However,the formed sp^(3)-C atoms could only be short-lived and gradually transformed to sp^(2)-C atoms with the graphitization generated on the wearing surface of the films.The radial distribution function and translational order parameter indicated that the films'high sp^(3)/sp^(2) ratio led to an increased sp^(2)-C proportion on the wear scar after friction,which caused an increased structural ordering. | Yefei ZHOU Zhihao CHEN Tao ZHANG Silong ZHANG Xiaolei XING Qingxiang YANG Dongyang LI | 2023 | Friction2023，11，9： | 0 |
