| 2 | Integrated simulation of the dualistic water cycle and its associated processes in the Haihe River Basin显示文摘Water resource shortages, water environmental deterioration, and water ecological degradation are becoming increasingly prominent in the Haihe River Basin under the effects of global climate change and intense human activity. Finding ways to solve these problems reasonably is an urgent task in basin water resources management. The water cycle describes the formation and transformation of every water drop, while it interacts with associated water ecology and water environment processes. Therefore, to fundamentally solve the above problems, the three processes must be combined and the evolutionary trends of the ecology and water environment driven by the water cycle must be determined. To comprehensively diagnose and solve the problems of water resources, ecology and water environment in the basin, an integrated simulation platform of the dualistic water cycle and its associated processes in the Haihe River Basin was established by fully analyzing the 'natural-social' dualistic characteristics of the evolution of the basin water cycle in this study. Accordingly, it is a supporting tool to evaluate the future trends of water resources, ecology and the water environment by setting scenarios based on the predictions of a climate mode and water control conditions. The results show that with climate change, the water consumption, groundwater overexploitation, and the amount of water flowing to the sea could develop soundly and satisfy the requirements of national economic growth in the future planning year 2030 through the implementation of water consumption control management and the South-North Water Diversion Project. Meanwhile, associated water environmental deterioration can be alleviated, and a growing trend for production capacities of the natural ecosystem and agro-ecosystem is seen. The above results provide a foundation for implementing basin water resources regulation and the most strict water resources management. | WANG Hao JIA YangWen YANG GuiYu ZHOU ZuHao QIU YaQin NIU CunWen PENG Hui | 2013 | Chinese Science Bulletin2013,58,27: | 10 |
| 3 | Necessity and feasibility for an ET-based modern water resources management strategy: A case study of soil water resources in the Yellow River Basin显示文摘The necessity and feasibility of an ET-based modern water resources management was analyzed to improve assessment of critical water resources scarcity in the region/basin. This analysis was based on the whole water cycle process and its analysis object is evapotranspiration (ET), a main consumption component in the water resources dynamic transformation process. A case study was undertaken by selecting soil water resources in the Yellow River Basin and employing the WEP-L distributed hydrological model with physics mechanisms. This paper discusses the amount and consumption efficiency of soil-water resources according to completely simulated results of water cycle elements throughout the basin. Results indicate that it is important for the ET-based modern water resources management strategy to alleviate water resources scarcity because it may not only avoid unused water wasting but also improve water use efficiency. Therefore, an ET-based modern water resources management scheme is a good complement to the traditional water resources demand management system. | WANG Hao YANG GuiYu JIA YangWen QIN DaYong GAN Hong WANG JianHua HAN ChunMiao | 2009 | Science China(Technological Sciences)2009,52,10: | 6 |
| 4 | Study on integrated calculation of ecological water demand for basin system显示文摘The operation of reservoir(s) has a certain impact on the downstream hydrologic regime,and even endangers the ecological water safety of river corridor and ecosystems which interact with river system.Therefore,ecological operation needs to be carried out in order to ensure ecological water use of downstream zone.The key technological support is the estimation and integrated calculation of ecological water demand.The connotation of the integrated calculation on ecological water demand lies on that the ecological water demand of different ecosystems is integrated to meet the requirements of water allocation and operation on watershed scale in terms of hydrological cycle.Considering the practical requirement of ecological operation of reservoir(s),this study proposed an integrated calculation approach of ecological water demand according to the ecological water demand in various ecosystems as well as the hydraulic connection among them;it established an integrated calculation model of regional ecological water demand by means of the distributed hydrological model,and studied the integrated calculation in Yalong River basin which is the source area of the west route of South-North Water Transfer Project as an example.The results indicated that the integrated calculation model more effectively combined the ecological water demand and hydraulic connection of ecosystems in time and space,compared with the lumped water balance analysis,since the former conquered the defect of insufficient ecological water source and supplement on multiple spatial and temporal scales,and met the demand of ecological operation of reservoir(s). | JIN Xin YAN DengHua WANG Hao ZHANG Cheng TANG Yun YANG GuiYu WANG LingHe | 2011 | Science China(Technological Sciences)2011,54,10: | 4 |
| 5 | Effects of Long-term Fertilization on Soil M icrobial Com m unity Structure,Labile Organic Carbon and Nitrogen and Enzym e Activity in Paddy Field and Upland显示文摘To investigate the effects of long-term fertilization systems on soil microbial community structure,labile organic carbon and nitrogen and enzyme activity in yellow sand paddy field and upland,a field experiment was conducted at the experimental station of Dongyang Institute of Maize Research in Zhejiang Province,China in 2009.The experiment consisted of six treatments with three replicates,and they were arranged in a completely randomized design,including no fertilization in paddy field (PCK),conventional fertilization in paddy field (PCF),formulated fertilization by soil testing in paddy field (PSTF),formulated fertilization by soil testing with organic manure in paddy field (PSTF+OF),conventional fertilization on upland (DCF),and formulated fertilization by soil testing with organic manure on upland (DSTF+OF).Soil nutrients,enzyme activity,microbial biomass and community structure were determined in 2015.The results showed that compared with no fertilization in paddy field (PCK),fertilization increased soil phosphorus and potassium content,and decreased pH value.No fertilization in paddy field (PCK) had no significant effect on soil culturable microorganisms in paddy field and upland,but formulated fertilization by soil testing with organic manure on upland (DSTF+OF) significantly increased the number of fungi.Formula fertilization by soil testing with organic manure (PSTF+OF) also significantly increased soil microbial biomass carbon and nitrogen in paddy field and upland.Moreover,fertilization had no significant effect on soil cellulase activity,but formula fertilization by soil testing with organic manure (PSTF+OF) significantly increased soil dehydrogenase and catalase activity.Therefore,long-term application of chemical fertilizer with organic fertilizer can effectively improve soil fertility. | Wang Guiyue Su Ting Han Hailiang Tan Heping Bao Fei Zhao Fucheng | 2019 | Meteorological and Environmental Research2019,10,5: | 4 |

| 7 | Performance improvement of optimization solutions by POD-based data mining显示文摘The performance of an optimized aerodynamic shape is further improved by a second-step optimization using the design knowledge discovered by a data mining technique based on Proper Orthogonal Decomposition(POD) in the present study. Data generated in the first-step optimization by using evolution algorithms is saved as the source data, among which the superior data with improved objectives and maintained constraints is chosen. Only the geometry components of the superior data are picked out and used for constructing the snapshots of POD. Geometry characteristics of the superior data illustrated by POD bases are the design knowledge, by which the second-step optimization can be rapidly achieved. The optimization methods are demonstrated by redesigning a transonic compressor rotor blade, NASA Rotor 37, in the study to maximize the peak adiabatic efficiency, while maintaining the total pressure ratio and mass flow rate.Firstly, the blade is redesigned by using a particle swarm optimization method, and the adiabatic efficiency is increased by 1.29%. Then, the second-step optimization is performed by using the design knowledge, and a 0.25% gain on the adiabatic efficiency is obtained. The results are presented and addressed in detail, demonstrating that geometry variations significantly change the pattern and strength of the shock wave in the blade passage. The former reduces the separation loss,while the latter reduces the shock loss, and both favor an increase of the adiabatic efficiency. | Yanhui DUAN Wenhua WU Peihong ZHANG Fulin TONG Zhaolin FAN Guiyu ZHOU Jiaqi LUO | 2019 | Chinese Journal of Aeronautics2019,32,4: | 3 |
| 8 | Construction of Rat Model of Hepatic Fibrosis with Blood Stasis Syndrome Integrated with Traditional Chinese Medicine(TCM)Syndrome and Western Medicine Disease显示文摘[Objective]According to the theory of blood stasis in traditional Chinese medicine( TCM),the animal modeling method of hepatic fibrosis integrated with pathology and symptoms was explored and improved,to construct a new type of rat model of hepatic fibrosis with blood stasis syndrome integrated with traditional Chinese and western medicine. [Method]The hepatic fibrosis model of blood stasis with blood stasis syndrome was constructed by jointing multi factors,including intragastric administration of ethanol,high fat and low protein feeding,joint injection of dimethylnitrosamine( DMN),bovine serum albumin( BSA) and norepinephrine( NE). The modeling method was further compared with traditional CC14 single-factor modeling method from the aspects of mortality,blood stasis syndrome of TCM,syndrome grading,general morphology of liver pathology,liver function changes,as well as expression levels of three kinds of collagen( type I and type III collagen,α-SMA) determined by immunohistochemical staining method,and four items of rat hepatic fibrosis( HA,P3 NP,LN,CⅣ content) determined by radio enzyme immunoassay. [Result]In blood stasis group,(1) the mortality of rats was 20%;(2) model rats appeared typical blood stasis syndromes of TCM such as ecchymosis,dark purple tongue,loose stool,and blood stasis syndrome grading was high;(3) fibrosis changes of liver such as dark white surface,dense gray nodules and brittle texture were observed in general morphological examination;(4) serological liver function tests found that ALT and AST of model rats,as well as TBIL,DBIL and IBIL contents increased significantly;(5) immunohistochemical staining demonstrated that the expression levels of three kinds of collagen(type I and type III collagen,α-SMA) increased significantly;(6) four items of rat serum hepatic fibrosis,HA,P3 NP,LN,CⅣ content,increased significantly;(7) the above results in blood stasis syndrome model group(except morality and liver function) were higher than those in CC14 modeling group,and the difference was statistically significant( P < 0. 05). [Conclusion]The new improved modeling method effectively reduces high mortality in traditional CC14 modeling method.In addition to low mortality,the model animal has dual characteristics of disease in western medicine and syndrome in TCM. It is consistent with the pathological characteristics of hepatic fibrosis in western medicine when according with the basic characteristics of blood stasis syndrome in TCM. | Peng Yue Duan Xuelin Zhao Tiejian Yao Le Wei Yanfei Li Guiyu | 2017 | Animal Husbandry and Feed Science2017,9,2: | 3 |
| 9 | Study on consumption efficiency of soil water resources in the Yellow River Basin based on regional ET structure显示文摘Based on the regional water resources character, the concept of soil water resources is first redefined, and then associated with their transfer relationship in the hydrological cycle, Evapotranspiration (ET)-based consumption structure and consumption efficiency of soil water resources are analyzed. According to ET 's function in productivity, the consumption efficiency of soil water resources is di- vided into three classes: high efficient consumption from vegetation transpiration, low efficient con- sumption from soil evaporation among plants with high vegetation coverage and inefficient consump- tion from soil evaporation among plants with low vegetation coverage and bare soil evaporation. The high efficient and low efficient consumption were further classified as productive consumption. The ineffi- cient consumption is considered non-productive consumption because it is significant in the whole hydrological cycle process. Finally, according to these categories, and employing a WEP-L dis- tributed hydrological model, this paper analyzes the consumption efficiency of soil water resources in the Yel- low River Basin. The results show that there are 2078.89×108 m3 soil water resources in the whole basin. From the viewpoint of consumption structure, the soil water resources are comprised of 381.89×108 m3 transpiration consumption from vegetation and 1697.09×108 m3 evaporation consumption from soil among plants and bare soil. From the viewpoint of consumption efficiency, soil water re- sources are composed of 920.11×108 m3 efficient consumption and 1158.86×108 m3 of inefficient con- sumption. High efficient consumption accounts for 41.5 percent of the total efficient consumption of the whole basin, low efficient for 58.5 percent. Furthermore, consumption efficiency varies by region. Compared with ET from different land use conditions, the whole basin appears to follow the trend of having the greatest proportion of consumption as inefficient consumption, followed by low efficient consumption, and then the least proportion as high efficient consumption. The amount of inefficient consumption in some regions with vegetation is less than in other regions without vegetation. The amount of inefficient consumption in grasslands is much greater than in forestlands. However, the proportion of low efficient consumption is the greatest in crop fields. The amount of high efficient con- sumption in grasslands and forelands is similar to the corresponding low efficient consumption. However, the low efficient consumption in grasslands is larger than in the forelands. Therefore, when adjusting the utilization efficiency of soil water resources, vegetation coverage and plant structure should be modulated in terms of the principle of decreasing inefficient consumption, improving low efficiency ET and increasing high efficiency ET according to area character. | WANG Hao YANG GuiYu JIA YangWen QIN DaYong | 2008 | Science China Earth Sciences2008,51,3: | 3 |
| 10 | Effects of Aqueous Extract of Plumbago zeylanica L. in the Reversal of DMN-induced Hepatic Fibrosis in Rat显示文摘[Objectives] This study was conducted to evaluate the action of the aqueous extract of a medicinal plant Plumbago zeylanica L. in the reversal of dimethylnitrosamine( DMN)-induced hepatic fibrosis in rats,and to provide a scientific basis for the utilization of P. zeylanica in treatment of hepatic fibrosis. [Methods] Hepatic fibrosis in rats was induced by intraperitoneal injection of DMN. The rats were then given the aqueous extract of P. zeylanica at high,medium or low concentration by gavage for five weeks. Serum level of alanine aminotransferase( ALT) was determined by lactate dehydrogenase( LDH)-release assay,and serum level of aspartate transaminase( AST) was measured by UV-malate dehydrogenase( MDH) assay. Serum levels of total bilirubin( TBIL),direct bilirubin( DBIL)and indirect bilirubin( IBIL) were measured by vanadate oxidation assay. Four indices of hepatic fibrosis( hyaluronic acid,laminin,procollagen type Ⅲ and collagen type IV) were determined by radioimmunoassay( RIA) assay. Morphological damage of liver tissue was observed by hematoxylin-eosin staining( H&E staining). Immunohistochemical staining was performed to determine the location and area of deposited collagen type I,collagen type Ⅲ and α-smooth muscle actin( α-SMA) in liver tissue. [Results]Compared with the negative control( rats with diseased liver and untreated with P. zeylanica aqueous extract),the serum levels of ALT,AST,TBIL,DBIL and IBIL were significantly decreased by P. zeylanica aqueous extract; the levels of the four serum indices of hepatic fibrosis were also obviously reduced. H&E staining showed that hepatic fibrosis in rats was obviously inhibited or even reversed by P. zeylanica aqueous extract. Immunohistochemical staining proved that the aqueous extract of P. zeylanica significantly reduced the area and coloration of collagen type I,collagen type Ⅲ and α-SMA in rat liver. [Conclusions] The aqueous extract of P. zeylanica has a definite effect in reversal of DMN-induced hepatic fibrosis in rat by promoting the recovery of liver function,reversal of histopathological changes and reducing fibrotic collagen. | Yue PENG Xuelin DUAN Tiejian ZHAO Yanfei WEI Guiyu LI Lulu LIU | 2017 | Agricultural Biotechnology2017,6,3: | 3 |

| 12 | Evaluation of stearic acid/coconut shell charcoal composite phase change thermal energy storage materials for tankless solar water heater显示文摘This work presents a cost-effective and environment-friendly form-stabilized phase change material(PCM)and corresponding solar thermal application in the tankless solar water heater(TSWH).Coconut shell charcoal(CSC)as supporting material was modified by moderate oxidant of H_(2)O_(2)with different concentrations,and then sta-bilized stearic acid(SA)to prepare composite PCMs through vacuum impregnation.It found that CSC support causes a 15.70%improvement of SA loadage after treated by 15%H_(2)O_(2)due to coefficient enhancement by phys-ical interaction and surface modification.The modified CSC 15 support appears more super macropores which contribute to the impregnation of SA than non-modified CSC 0 support verifying from SEM and BET results.And the content of oxygen functional groups was increased after oxidation modification,also motivating SA stabiliza-tion by hydrogen bond interaction in XPS analysis.FTIR results proved there is no chemical reaction happened between SA and CSC.Moreover,the latent heat and phase transition temperature of the as-prepared SA/CSC 15 composite are 76.69 J g^(−1)and 52.52℃,respectively.All composites exhibit excellent thermal stability under a working temperature of 180℃and form stability during phase change.Thermal energy storage-release test within 70℃presents the composite has fast heat transfer efficiency than pure SA.The composite filled in TSWH system has 0.75 W m^(−1)K^(−1)thermal conductivity which is 2.88 times higher than that of pure SA(0.26 W m^(−1)K−1).Besides,the TSWH system with a flow rate of 0.004 kg s^(−1)could heat water effectively after sunset and the energy obtained from the thermal storage system within 1830 s testing times is about 0.15 kW h.In all,SA/CSC composite with good physical-thermo properties has potential in thermal energy storage application,especially in solar energy storage. | Baoshan Xie Chuanchang Li Bo Zhang Lixin Yang Guiyu Xiao Jian Chen | 2020 | Energy and Built Environment2020,1,2: | 1 |

| 16 | Graph-based image segmentation using directional nearest neighbor graph显示文摘Graph-based image segmentation techniques generally represent the problem in terms of a graph.In this work,we present a novel graph,called the directional nearest neighbor graph.The construction principle of this graph is that each node corresponding to a pixel in the image is connected to a fxed number of nearest neighbors measured by color value and the connected neighbors are distributed in four directions.Compared with the classical grid graph and the nearest neighbor graph,our method can capture low-level texture information using a less-connected edge topology.To test the performance of the proposed method,a comparison with other graph-based methods is carried out on synthetic and real-world images.Results show an improved segmentation for texture objects as well as a lower computational load. | LIU Zhao HU DeWen SHEN Hui FENG GuiYu | 2013 | Science China(Information Sciences)2013,56,11: | 1 |
