| 1 | Eco-environment range in the source regions of the Yangtze and Yellow rivers显示文摘Based on geographical and hydrological extents delimited, four principles are identified, as the bases for delineating the ranges of the source regions of the Yangtze and Yellow rivers in the paper. According to the comprehensive analysis of topographical characteristics, climate conditions, vegetation distribution and hydrological features, the source region ranges for eco-environmental study are defined. The eastern boundary point is Dari hydrological station in the upper reach of the Yellow River. The watershed above Dari hydrological station is the source region of the Yellow River which drains an area of 4.49×10 4 km 2 . Natural environment is characterized by the major topographical types of plateau lakes and marshland, gentle landforms, alpine cold semi-arid climate, and steppe and meadow vegetation in the source region of the Yellow River. The eastern boundary point is the convergent site of the Nieqiaqu and the Tongtian River in the upstream of the Yangtze River. The watershed above the convergent site is the source region of the Yangtze River, with a watershed area of 12.24×10 4 km 2 . Hills and alpine plain topography, gentle terrain, alpine cold arid and semi-arid climate, and alpine cold grassland and meadow are natural conditions in the source region of the Yangtze River. | DING Yongjian,YANG Jianping,LIU Shiyin,CHEN Rensheng,WANG Genxu,SHEN Yongping,WANG Jian,XIE Changwei,ZHANG Shiqing(Cold and Arid Regions Environmental and Engineering Research Institute, CAS, Lanzhou 730000, China) | 2003 | Journal of Geographical Sciences2003，13，2： | 18 |
| 2 | Monitoring of frozen soil hydrology in macro-scale in the Qinghai-Xizang Plateau显示文摘Monitoring of frozen soil hydrology in macro-scale was performed by Chinese and Japanese scientists from 1997 to 1998. Quality measured data were obtained. Measured data on soil moisture and temperature are preliminarily analyzed. Based on profiles of soil temperature and moisture in individual measured sites, intra-annual freezing and melting process of soil is discussed. Maximum frozen and thawed depths and frozen days in various depths are estimated. The work emphasized the spatial distribution on soil temperature and moisture in macro-scale and the effect of topography on conditions of soil water and heat. | Yongjian Ding Baisheng Ye Shiying Liu Yongping Shen Shaoling Wang Meixie Yang | 2000 | Chinese Science Bulletin2000，45，12： | 13 |
| 3 | Overemployment,executive pay-for-performance sensitivity and economic consequences:Evidence from China显示文摘Using a sample of state-owned enterprises(SOEs) listed on the Shanghai and Shenzhen Stock Exchanges during the 1999-2009 period,we investigate the effects of overemployment on executives' pay-for-performance sensitivity(PPS) and analyze how the behavior of firms with high/low PPS affects the number of surplus employees.We find the existence of a redundant workforce significantly weakens PPS and the role of accounting measures in performance assessment.In contrast to prior literature,we find that higher PPS is associated with a stronger incentive to lay off redundant employees and to limit future employee numbers.We also find that weaker government intervention strengthens managerial control over the future size of the workforce.Finally,our findings suggest that a heavier government policy burden on SOEs leads to lower tax rates and more government gains. | Donghua Chen Yongjian Shen Fu Xin Tianqin Zhang | 2012 | China Journal of Accounting Research2012，，1： | 8 |
| 4 | Regional difference of annual precipitation and discharge variation over west China during the last 50 years显示文摘Using annual precipitation and discharge data measured in the past five decades,this paper analyzed the regional differences over west China in terms of climate and discharge variations,and investigated the relationship between the regional characteristics and the activities of South and East Asian sum-mer monsoon. Results revealed that the precipitation and discharge in the upper reaches of the Yellow River (Central West China) have a negative correlation with those in Xinjiang (northwest China) and the Yarlung Zangbo River (the upper reaches of the Brahmaputra Rive,southwest China) regions. The geographical patterns of precipitation and discharge variations are different over west China,i.e. the regional climate displays the alteration of dry-wet-dry or wet-dry-wet from north to south in west China. The negative correlation of annual discharges between Xinjiang and the upper reaches of the Yellow River is found statistically significant in the decadal scale,and that between the Yarlung Zangbo River and the upper reaches of the Yellow River is found active in the interannual scale. The regional char-acteristics indicate that the discharge/precipitation variations in the upper reaches of the Yellow River are dominated by the East Asian summer monsoon while their variations in Xinjiang are affected by both the west wind and East Asian summer monsoon. | DING YongJian YE BaiSheng HAN TianDing SHEN YongPing LIU ShiYin | 2007 | Science China Earth Sciences2007，50，6： | 7 |
| 5 | Does EVA performance evaluation improve the value of cash holdings? Evidence from China显示文摘This paper investigates the influence of the economic value added(EVA)performance evaluation,issued in 2010 by the State-owned Assets Supervision and Administration Commission of the State Council,on the value of the cash holdings of central state-owned enterprises(CSOEs).We find that EVA performance evaluation has some influence on the overinvestment of CSOE cash holdings and significantly increases the value of CSOE cash holdings compared with the cash holdings of local state-owned enterprises.The greater value of CSOE cash holdings derives from underinvestment modification and overinvestment restraint.The value of cash holdings increases more for companies with better accounting performance.Thus,the EVA performance evaluation policy increases CSOE efficiency.This study contributes to the emerging literature related to cash holdings and the economic consequences of the EVA performance evaluation policy.It expands the literature related to investor protection in countries experiencing economic transition. | Yongjian Shen Lei Zou Donghua Chen | 2015 | China Journal of Accounting Research2015，，3： | 6 |
| 6 | Nematode Diversity of Qingdao Coast Inferred from the 18S Ribosomal RNA Gene Sequence Analysis显示文摘The 18S ribosomal DNA gene (18S rDNA) sequences (approximately 1300 bp in length) were amplified from the DNA extracted from the free-living marine nematodes collected from the inter-tidal sediment of Qingdao coast in bulk with nematode spe- cific primers. The PCR products were cloned, re-amplified, digested with Rsa I and Hin6 I restriction endonucleases and separated in agarose gel. Among 17 restriction fragment length types, types 1, 2 and 6 covered 61.2%, 14.4% and 9.3% of the clones analyzed, respectively, while the remaining 14 only covered 21 clones, which accounted for 15.1% of the total. Twenty-four representative clones were sequenced and phylogenetically analyzed by referring to those currently available in RDP and GenBank databases. Al- though it was hard to assign these sequences to known species or genera due to the lack of the 18S rDNA sequence data of known marine free-living nematodes, the obtained sequences were assigned to the nematodes of Adenophorea. Among them, twelve se- quences were close to Pontonema vulgare and Adoncholaimus sp., four to Daptonema procerus and two (identical) to Enoplus brevis. Our results showed that free-living marine nematode diversities could be determined by PCR retrieving and analysis of the 18S rDNA sequences and an 18S rDNA sequence could be assigned to a species or a genus only if the 18S rDNA sequences of the free-living marine nematodes were accumulated to some extent. | SHEN Xiquan YANG Guanpin LIU Yongjian | 2007 | Journal of Ocean University of China2007，6，2： | 3 |

| 8 | Timing earnings显示文摘Since the opening of China's securities market,there have been a number of bull and bear cycles.This paper discusses how executives use the market timing approach to manage earnings in different cycles to maximize firm value.We find that Chinese listed companies choose to release more earnings during bull markets and this phenomenon is more evident in companies that are more profitable and have higher valuations.We also find that executives who do not release more earnings during bull markets are more likely to be dismissed. | Donghua Chen Xiangqin Qi Yongjian Shen Huimiao Lin | 2011 | China Journal of Accounting Research2011，，4： | 2 |
| 9 | Performance Volatility and Wage Elasticity:An Examination of Listed Chinese A-share Enterprises显示文摘The management of future financial risk on the part of managers and changes in firm finances are two of the fundamental reasons for upward and downward rigidity of wages.The proxy variable for firm financial risk is volatility,the past performance of which is among the principal indicators of wage rigidity.In firms whose current performance is on the upswing,the greater the volatility in past performance,the smaller the elasticity ratio and the more acute the upward rigidity;the more stable past performance,the larger the elasticity ratio and the more acute the upward elasticity.In firms in which current performance is declining,greater past performance volatility leads to a larger elasticity ratio and more acute downward rigidity,whereas more stable such performance leads to a smaller elasticity ratio and more acute downward rigidity. | Donghua Chen Yongjian Shen Lihua Chen | 2009 | China Journal of Accounting Research2009，，2： | 2 |
| 10 | A Novel Routing Method for Social Delay-Tolerant Networks显示文摘The lack of continuous connectivity and a complete path from source to destination makes node communication quite difficult in Delay-Tolerant Networks(DTNs). Most studies focus on routing problems in idealized network environments without considering social properties. Communication devices are carried by individuals in many DTNs; therefore, DTNs are unique social networks to some extent. To design efficient routing protocols for DTNs, it is important to analyze their social properties. In this paper, a more accurate and comprehensive metric for detecting the quality of the relationships between nodes is proposed, by considering the contact time, contact frequency, and contact regularity. An overlapping hierarchical community detection method is designed based on this new metric, and a tree structure is built. Furthermore, we exploit the overlapping community structure and the tree structure to provide message-forwarding paths from the source node to the destination node.The simulation results show that our Routing method based on Overlapping hierarchical Community Detection(ROCD) achieves better delivery rate than SimBet and Bubble Rap, the classic routing protocols, without affecting the average delay. | Xiangyu Meng Gaochao Xu Tingting Guo Yongjian Yang Wenxu Shen Kuo Zhao | 2019 | Tsinghua Science and Technology2019，24，1： | 2 |

| 17 | Effects of Different Antibiotics Substitutes on Production Performance of Fattening Pigs显示文摘[Objective] The aim was to discuss effects of different antibiotics substitutes on production performance of fattening pigs,and to lay a foundation for development and application of antibiotics-free pig feed.[Method]By adding 100 mg/kg compound probiotics,100 mg/kg compound enzyme preparation,500 and 1 000 mg/kg eu-commin in the basal diet,binary hybrid pigs weighing about 15 kg were reared for 102 d,and the feed added with 300 mg/kg colistin sulfate was used as control.[Result] Using compound probiotics and compound enzyme preparation to substitute antibiotics had no adverse effects on daily weight gain,daily feed intake and feed gain ratio of 15-90 kg fattening pigs; using eu-commin to substitute antibiotics had no adverse effect on daily weight gain,daily feed intake and feed gain ratio of 15-30 kg fattening pigs,but had significant influence on daily weight gain of 30- 90 kg fattening pigs (P<0.05).[Conclusion] It is feasible to develop antibiotics-free pig feed by using new type of green environmental-friendly additive instead of antibiotics. | Sha Wenfeng Zhu Juan Gu Yongjian Zhang Ruixiang Shen Jun | 2016 | Animal Husbandry and Feed Science2016，8，5： | 0 |
| 18 | Sedimentary Records and Environmental Analysis of the Ximencuo Lake in Northeast Qinghai-Tibet Plateau in the Past 1,700 Years显示文摘Lake sediment is the recorder of historical climate fluctuation and basin environment change. This study collected the Ximencuo Lake sediment in source area of the Yellow River, analyzed organic matters and geochemical elements of the core, obtained nearly environment changes of the past 1,720 years. The results showed the environment evolution process of the 47-cm columnar core can be divided into four stages: below 32 cm(before 900 A.D.), corresponding to the cool and wet climate; 32–20 cm(900 A.D–1300 A.D.), corresponding to the warming temperature and decreasing precipitation; between 20–3.5 cm(1300–1900 A.D.), the stage is more consistent with the Little Ice Age, and precipitation gradually reduced; 3.5–0 cm(since 1900 A.D.), this is the twentieth Century warming period with increasing temperature and reduced precipitation. Phosphorus content increased rapidly in the last 20 years, reflecting the continuously increasing human interventions, but before this period, the P content was low and stable, indicating the natural background of regional phosphorus content. | SHEN Defu LI Shijie JIANG Yongjian | 2016 | Journal of Landscape Research2016，8，1： | 0 |
| 19 | Energy Balance of Irrigated Intercropping Field in the Middle Reaches of Heihe River Basin显示文摘Based on the experiments conducted in an irrigated intercropping field in Zhangye Oasis in the middle reaches of Heihe River basin in 2004, the characteristics of radiation budget are analyzed. Furthermore, energy balance is cal- culated by using Bowen-Ratio Energy Balance (BREB) method. The results show that the ratio of the absorbed radiation to the incoming short radiation in intercropping crop canopy-soil system is increasing with growing stages, from 0.81 in the initial growing stage (IGS) to 0.86 in the late growing stage (LGS). The net radiation, which is smaller in IGS, in- creases rapidly in the first period of the middle growing stage (MGS) and reaches the maximum value in the second period of MGS. It then somewhat decreases in LGS. The ratio of net radiation to total radiation has a similar trend with the net radiation. In the whole growing stages, latent heat flux, which takes up 70% or so of the net radiation, is the dominant item in energy balance. Sensible heat flux shares 20% of the net radiation and soil heat flux has a percentage of 10%. The characteristics of heat balance vary distinctly in different growing stages. In IGS, the ratios of latent heat flux, sensible heat flux and soil heat flux to net radiation are 44.5%, 23.8% and 31.7% respectively. In MGS, with the in- creasing of latent heat flux and the decreasing of sensible heat flux and soil heat flux, the ratios turn into 84.4%, 6.3% and 9.3%. In LGS, the soil heat flux maintains 0W/m2 or so, and latent heat flux and sensible heat flux take up 61.4% and 38.6% respectively. The energy balance also shows an obvious daily variation characteristic. | WU Jinkui DING Yongjian WANG Genxu SHEN Yongping Yusuke YAMAZAKI Jumpei KUBOTA | 2006 | Chinese Geographical Science2006，16，3： | 0 |
| 20 | Growth of Erbium Dihydride Films under Low Hydrogen Pressure by Pulsed Laser Deposition显示文摘Erbium dihydride thin films were prepared by pulsed laser deposition on Si(100) substrates using erbium target under different low hydrogen pressures. The properties of these films were examined by atomic force microscopy, X-ray diffractometer, transmission electron microscopy, and Fourier transform infrared spectroscopy and UV-vis spectroscopy. Surface morphology reveals the smooth surface of these films(RMS: from 0.503 to 2.849 nm). The presence of obviously-broadened peaks for diffraction planes(111) suggests a presence of very tiny crystallites distributed along a preferred crystallographic orientation. Transmission electron microscopy investigations confirmed the formation of tiny crystallites due to the implantation of erbium ions. Due to the increase of nominal H concentration, the intensity of the broad absorbance from 190-260 nm increased. | 王雪敏 SHEN Changle WANG Yuying PENG Liping LI Weihua YAN Dawei 吴卫东 TANG Yongjian | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，1： | 0 |
