Yunnan University of finance and Trade recording to t he statistics of chain’s output of tea, Yunnan province has entered the ranks of the larger ones of the production in china. Yunnan’s tea industry has the natur al resources and the economic effects envied, on the orther hand, Yunnan’s tea m arket has gradually become less and the economic effects have been poor. Through our comprehensive investigation and study, we consider that because the supply chain has seriously been disjointed among production, supply and sale of tea ind ustry in Yunnan, the supply chain of Yunnan’s tea industry need to be reorganize d for the promoting the development of Yunnan’s tea industry. The essence of reengineering of Yunnan’s tea industrial supply chain is to set u p the model of the trailed operation,to strengthen the strategic partnership man agement between the supply chain, to optimize the design of the supply chain and build up and improve the working mechanism for management of the tea industrial supply chain. The structure of Yunnan’s model of tea industrial supply chain: the model of com mercial flow; the model of logistics flow; the model of {2. flow and the model of cash flow. The solutions and policies for the reorganization of Yunnan’s tea industrial sup ply chain: planning, logistics and distribution and sales. set up the supporting system of {2. technology. Build up the control system of production and *** the working mechanism of Yunnan’s tea industrial supply chain. Implement the engineering of exporting Yunnan’s tea into the markets of other p rovinces and foreign markets. Have many the channels that raise the funds of dev elopment for Yunnan’s tea industry.

After having analyzed the requirement on the aerodynamic earth’s surface rough- ness in two-dimensional distribution in the research field of interaction between land surface and atmosphere, this paper presents a new way to calculate the aerodynamic roughness using the earth’s surface geometric roughness retrieved from sAR (synthetic Aperture Radar) and TM thermal infrared image data. On the one hand, the sPM (small Perturbation Model) was used as a theoretical sAR backscattering model to describe the relationship between the sAR back- scattering coefficient and the earth’s surface geometric roughness and its dielectric constant re- trieved from the physical model between the soil thermal inertia and the soil surface moisture with the simultaneous TM thermal infrared image data and the ground microclimate data. On the basis of the sAR image matching with the TM image, the non-volume scattering surface geo- metric information was obtained from the sPM model at the TM image pixel scale, and the ground pixel surface’s equivalent geometric roughness—height standard RMs (Root Mean square) was achieved from the geometric information by the transformation of the typical to- pographic factors. The vegetation (wheat, tree) height retrieved from spectrum model was also transferred into its equivalent geometric roughness. A completely two-dimensional distribution map of the equivalent geometric roughness over the experimental area was produced by the data mosaic technique. On the other hand, according to the atmospheric eddy currents theory, the aerodynamic surface roughness was iterated out with the atmosphere stability correction method using the wind and the temperature profiles data measured at several typical fields such as bare soil field and vegetation field. After having analyzed the effect of surface equivalent geo- metric roughness together with dynamic and thermodynamic factors on the aerodynamic surface roughness within the working area, this paper first establishe

Using support Vector Machine to Predict Eco-environment Burden:A case study of Wuhan,Hubei Province,china

引用

Biomedical and environmental sciences 2008年第1期21卷 45-52页

作者： XIANG-MEI LI JING-XUAN ZHOU sONG-HU YUAN XIN-PING ZHOU QIANG FU school of environmental science and Engineering Huazhong University of Science and Technology Wuhan 430074 Hubei China china environmental Monitoring center Beijing 100029 China

Objective The human socio-economic development depends on the planet＇s natural capital. Humans have had a considerable impact on the earth, such as resources depression and environment deterioration. The objective of this study was to assess the impact of socio-economic development on the ecological environment of Wuhan, Hubei Province, china, during the general planning period 2.06-2.2.. Methods support vector machine （sVM） model was constructed to simulate the process of eco-economic system of Wuhan. socio-economic factors of urban total ecological footprint （TEF） were selected by partial least squares （PLs） and leave-one-out cross validation （LOOcV）. Historical data of socio-economic factors as inputs, and corresponding historical data of TEF as target outputs, were presented to identify and validate the sVM model. When predicted input data after 2.05 were presented to trained model as generalization sets, TEFs of 2.05, 2.06,…, till 2.2. were simulated as output in succession. Results Up to 2.2., the district would have suffered an accumulative TEF of 2..374 million gha, which was over 1.5 times that of 2.04 and nearly 3 times that of 1988. The per capita EF would be up to 3.019 gha in 2.2.. contusions The simulation indicated that although the increase rate of GDP would be restricted in a lower level during the general planning period, urban ecological environment burden could not respond to the socio-economic circumstances promptly. sVM provides tools for dynami{2.ssment of regional eco-environment. However, there still exist limitations and disadvantages in the model. We believe that the next logical step in deriving better dynamic models of ecosystem is to integrate sVM and other algorithms or technologies.

Department of environmental Engineering Peking University Beijing China The Key Laboratory of Water and sediment sciences Ministry of Education Beijing China Institute of Hydraulic Research YellowRiver Conservancy Commission Zhengzhou China

In view of river functions and the Minimum Water Demand for River Ecosystem (MWDRE), the water resources in the Lower Yellow River is further divided into three portions, i.e. water available for ecosystem (WE), water exploitable for socioeconomic purposes (Ws) and excess flood water (WF). corresponding conceptions and practical significances are expounded in details. The annual amount of the three portions of water resources from 1950 to 2.01 is worked out on the basis of the daily hydrologic data, and the division of different portions is discussed. The results indicate that although the essential water demand for river functions is considered preferentially, the amount of the WE has decreased dramatically while its proportion increased gradually since the 1950s, and the shortage to the MWDRE increased markedly; both the amount and the proportion of the Ws decreased notably. since the 1990s, the actual water consumption for socioeconomic purposes in the lower reaches of the river basin has already exceeded the maximum amount of the Ws and has to take over the WE which is already insufficient, hence not only the normal river functions are further disturbed and the river course shrinks greatly, but also the proportion and potential danger of the WF show no decreasing tendency in spite of the sharp decrease of upstream runoff.

Based on the fuzziness and impreciseness of water environmental system, the fuzzy arithmetic was used to simulate the fuzzy and imprecise relations in modeling river water quality. By defining the parameters of water quality model as symmetrical triangular fuzzy numbers, a two-dimensional fuzzy water quality model for sudden pollutant discharge is established. From the fuzzy model, the pollutant concentrations, corresponding to the specified confidence level of a, can be obtained by means of the a-cut technique and arithmetic operations of triangular fuzzy numbers. study results reveal that it is feasible in theory and reliable on calculation applying triangular fuzzy numbers to the simulation of river water quality.

Beijing 100089 China

The current pressure on production resources of North china Plain, such as land and water to feed the growing population, necessitates the assessment of the sustainability of farming practices. This study focuses on the sustainability of farming practices related to groundwater and soil fertility management. The assessment is based on selected site-specific key indicators and their established threshold limits. The current farming practices in the study area are clearly unsustainable. Only about 6% of the surveyed farm households practice sustainable farming. The study stresses that farming practice, which is economically sustainable, should not be promoted at the cost of environment. Holistic strategies need to be developed and implemented that aim at balanced use of inputs, which satisfy both productivity and {2. concerns.

chinese Physics B 2016年第3期25卷 440-444页

作者：辛艳辉袁胜刘明堂刘红侠袁合才 Department of information and Engineering North China University of Water Resources and Electric Power Key Laboratory for Wide Band Gap semiconductor Materials and Devices of Education School of Microelectronics Xidian University Department of Mathematics and information science North China University of Water Resources and Electric Power

The two-dimensional models for symmetrical double-material double-gate （DM-DG） strained si （s-si） metal-oxide semiconductor field effect transistors （MOsFETs） are presented. The surface potential and the surface electric field ex- pressions have been obtained by solving Poisson＇s equation. The models of threshold voltage and subthreshold current are obtained based on the surface potential expression. The surface potential and the surface electric field are compared with those of single-material double-gate （sM-DG） MOsFETs. The effects of different device parameters on the threshold voltage and the subthreshold current are demonstrated. The analytical models give deep insight into the device parameters design. The analytical results obtained from the proposed models show good matching with the simulation results using DEssIs.

To enrich the genomic information of the commercially important fish species, we obtained 5,063 high-quality expressed sequence tags (EsTs) from the muscle cDNA database of the mandarin fish (siniperca chuatsi). clustering analysis yielded 1,62. unique sequences including 443 contigs (from 3,881 EsT sequences) and 1,182.sin- gletons. BLAsTX searches showed that 959 unique sequences shared homology to proteins in the NcBI non-redundant database. A total of 740 unique sequences were functionally annotated using Gene Ontology. The 1,62. unique sequences were assigned to Kyoto Encyclopedia of Genes and Genomes reference pathways, and the results indicated that transcripts participating in nucleotide metabolism and amino acid metabolism are relatively abundant in s. chuatsi. Meanwhile, we identified 15 genes to be abundantly expressed in muscle of the mandarin fish. These genes are involved in muscle structural formation and regulation of muscle differentiation and development. The most remarkable gene in s. chuatsi is nuclease diphosphate kinase B, which is represented by 449 EsT sequences accounting for 8.86% of the total EsT sequences. Our work provides a transcript profile expressed in the white muscle of the mandarin fish, laying down a foundation in better understanding of fish genomics.
