As the interaction of humans and the water and soil resources, the water pollution about Chinese lake eutrophication and its basin is very outstanding.
Water quality of the offshore areas is mild pollution.
Professional talent shortage, lack of environmental audit staff with comprehensive knowledge Water pollution control environment audit involves legality, environment, statistics, accounting, auditing and other aspects, the quality of the audit team is proposed a new challenge.
The audit staffs in resources and environment engaged by audit institutions in China, whose professional background part are financial audit, part are resources and the environment.
Water pollution control project for management refers to the rivers and lakes basin of water pollution and formulate corresponding environmental program.

Compared with the commonly used author keyword / phrases, title words / phrases and abstract words / phrases, manual indexing words are selected by professionals according to the literature content, which have a strong normative, can avoid the difficulties to be faced during the content analysis process such as the words homonymy, synonym, singular and plural variations, tense voice changes and word length etc., as well as the interference of the results analysis caused by the difficulties largely.
As we can see, there is a strong correlation between the eight journals and the six soil pollution sub research fields, and all researchers should focus on the eight core journals such as Chemosphere, Journal of Hazardous Materials, Environmental Pollution, Water, Air, and Soil Pollution, Environmental Science and Technology, Science of the Total Environment, Journal of Environmental Quality, Soil and Sediment Contamination; except the eight core journals above, each sub field researchers should particularly pay attention to their respective journals, g01 ( Biodegradation, Bioremediation, Biotechnology) sub field researchers should focus on the six core journals such as Environmental Monitoring and Assessment, Environmental Toxicology and Chemistry, Journal of Environmental Sciences, Soil Biology and Biochemistry, Bioresource Technology, International Biodeterioration and Biodegradation, g02 ( Zinc, Lead, Metals) sub field researchers should focus on the six core journals such as Environmental
The analysis of the correlation between the soil pollution related literatures and the published journals shows that: eight journals are the core journals of the entire soil pollution research and all researchers should focus on the eight core journals, such as Chemosphere, Journal of Hazardous Materials, Environmental Pollution, Water, Air, and Soil Pollution, Environmental Science and Technology, Science of the Total Environment, Journal of Environmental Quality, Soil and Sediment Contamination.

But PVC film and plank have low degree of adhesive; water will open in bubble shortcomings.
Because of these shortcomings of PVC film, PVC film also caused distress and sheet bonding, bonding is low, the water will bubble open[7-10].
Early film stickers agents are generally used EVA emulsion, manufactured products showed water, heat and moisture performance is relatively low, for the use of plates have great shortcomings of the current domestic production and use of emulsion adhesive sheet there water on poor water resistance will be soaked, the low adhesive PVC film and sheet, PVC film itself, there are some factors that are not conducive to bonding (in production, adding a lot of places increasing agents, agents of small molecules sink caused by dialysis of PVC films and other material weak link, resulting in decreased adhesion, adhesion bad), PVC secondary development affected.
This issue through formulation screening, to determine the butyl acrylate monomer and methyl acrylate copolymer, synthesized a novel emulsion adhesive, a good solution to the problem of the adhesive PVC film, PVC film to improve the affinity with the floor, and to improve the traditional shortcomings of low water resistance adhesive has much room for development, need to develop a new type of adhesive bonding and the development of new technology to become an important issue now, and in order to meet public demand, the development of PVC film and sheet new bonding technology is urgent, the other benefit of our students have learned the basic courses, professional foundation courses, specialized courses and other theoretical knowledge as well as production internships and practical knowledge experiments mastery, flexible use[14-15]. 2 acrylate, vinyl acetate copolymer emulsion adhesive preparation Material: butyl acrylate (BA), vinyl acetate (VAC), acrylic acid, emulsifier, ammonium
persulfate (chemically pure), sodium lauryl sulfate (chemically pure) distilled water, ammonium persulfate (APS), OP , OS, sodium lauryl sulfate (SLS), acrylic acid (AA), PVA, sodium dihydrogen phosphate, polyvinyl butyral (PVAF).

Summary of theoretical method The basic principle of the Hall of three-dimensional The Hall of three-dimensional structure divides the system engineering activities into a compact seven stages and seven steps, at the same time also consider a variety of professional knowledge and skills which are required for in order to complete the stage and the steps.
T-project analyses of risk factors T hydropower project background T hydropower station is the last cascade development of river basin water resources of JinShaJiang River hydropower station.
And preliminary identification of the risk to divide the knowledge dimension as standard risk Unit Division of project was the first step, then when a risk identification risk unit, we adopt a combination of logic and time dimensions, recognize preliminary project risk and conclude the risk factors for water conservancy project logistics.
These three aspects all need a comprehensive technical and professional knowledge to support, so the measures taken are: to strengthen the argument, technical advice; to strengthen self - construction management, pay attention to the construction process, achieve program process control, establish the restriction mechanism; to strengthen the raw materials and equipment review gatekeeper, pay attention to the detection; strengthen supplier contact, pay attention to the liquidity of the information technology; strengthen risk control, pay attention to scientific and technological input technology
For water conservancy and hydropower projects, policies, government support, the relevant policy changes on the great influence of large equipment logistics T project, countermeasures for such risks can take the insurance clause, arrangement, government guarantee, government project support function, item company seeking legal adviser, signed a mutual agreement to guarantee way to avoid the risk of government policies and regulations.
