In this study, a risk-based management model is developed and applied to an industrial zone. The models proposed by the United States Environmental Protection Agency and Han Bing have been improved by adding a residual ratio of volatile organic compounds （VOC） after boiling and deleting the related parameters in half-life. Using this improved model, an integrated process was used to assess human health risk level in the study area. Compared with water quality analysis, the results highlight the importance of applying an integrated approach for decision making on risk levels and water protection. The results of this study demonstrated that：（1. Compared with these permissible level standards in china （GB 3838-2.02. and National Primary Drinking Water Regulations of the United States, the residents＇ daily life had not been affected by the groundwater in this area （except for relative bad water quality of HB3-4 and HB3-6）; （2. The typical detected organic contaminants of all groundwater samples were chloroform, carbon tetrachloride, trichloroethylene and tetrachloroethene, and the pollution sources were mainly industrial sources by preliminary investigations; （3） As for groundwater, the non-carcinogenic risk values of all samples do not exceed the permissible level of 1.0 and the carcinogenic risk values are relatively lower than the permissible level of 1.00E-06 to 1.00E-04; （4） Drinking water pathway of trichloroethylene and tetrachloroethylene mainly contribute to increasing the health risk of residents＇ in study areas; （5） In terms of non-carcinogenic risk and carcinogenic risk, the health risk order for drinking water pathway and dermal contact pathway was： drinking water pathway 〉 dermal contact pathway.

As one component of chinaFLUX, the measurement of CO2.flux using eddy covariance over subtropical planted coniferous ecosystem in Qianyanzhou was conducted for a long term. This paper discusses the seasonal dynamics of net ecosystem exchange (NEE), ecosystem respiration (RE) and gross ecosystem exchange (GEE) between the coniferous ecosystem and atmosphere along 2.03 and 2.04. The variations of NEE, RE and GEE show obvious seasonal variabilities and correlate to each other, i.e. lower in winter and drought season, but higher in summer; light, temperature and soil water content are the main factors determining NEE; air temperature and water vapor pressure deficit (VPD) influence NEE with stronger influence from VPD. Under the proper light condition, drought stress could decrease the temperature range for carbon capture in planted coniferous, air temperature and precipitation controlled RE; The NEE, RE, and GEE for planted coniferous in Qianyanzhou are -387.2.gC·m-2.a-1.1.2..3 g C·m-2.a-1. -1.1..4 g C·m-2.a-1.in 2.03 and -42..8 g C·m-2.a-1. 1.42.0 g C·m-2.a-1. -1.65.8 g C·m-2.a-1.in 2.04, respectively, which suggest the intensive ability of plantation coniferous forest on carbon absorbing in Qianyanzhou.

A new method for the preparation of oligonucleotide microarray for gene expression detection was found. The key techniques and standards of quality controlling for preparation of oligonucleotide microarray was explored using gene of human 2.kD highly protein and Luciferase and mouse cytokine-associated genes. By the using of a software system MProbe, oligonucleotide probes were designed and BLAST. All the probes have a very high specificity, i.e. except target sequence, the similarity between the probe and non-target sequences is less than 70% and the hairpin structure are not exist in all *** the probes have the same length 40. GC contents in all probes are in a narrow scope (from 45% to 55%). All the probes are modified with amino at 5′ or 3′ terminal. The satisfied images with good sensativity and very high specificity were obtained by the using of the methods above and also using of positive and negative controls and some internal controls(house keeping gene) to quantitate and balance expression of genes. High specificity, good sensativity and stablity have been verified by three continuous experiments using the oligonucleotide microarray to study gene expression profile of normal mouse breast grand tissue .The oligonucleotide microarray for expression detection prepared using our method have high specificity, good sensativity and stablity et al . It may be a more advanced method for analysis of gene expression profile.

The concept of stickiness in this study was borrowed from information research literature, which indicated the complex and difficulties in all process of knowledge transfer that including knowledge acquisition. To reveal the stickiness of agriculture knowledge acquisition in china, a survey was conducted of agriculture related websites in china. Firstly, an intensive literature review was done for collecting attributes closely associated with agriculture knowledge and its acquisition process. Secondly, these attributes were cate- gorized and transformed into questionnaire and surveyed in {2. provinces in china. Thirdly, the data were tested with principal component analysis methods. As results, this study concluded that four factors that may affect the stickiness of agriculture knowledge, namely, difficulty, special tacitness, available explicitness, and proven knowledge;five factors that may affect stickiness of agriculture experts. They include attitudes, professional, expression capability, teamwork, and protectiveness;and five factors that may affect stickiness of agriculture institutions, attitudes, service orientation, distance, protectiveness, and professional. In conclusion, it was suggested that the three groups of principal factors can be used to guide the planning and assessment of ICT-based knowledge projects in rural areas. The study also highlighted a new area for ICT-based information and knowledge transfer research.
