Study On The Application Of Risk Assessment In Plan Environmental Impact Assessment

Environmental Impact Assessment is one way of correctly understanding the relation among the economic development,social development and environment development. Environmental Impact Assessment is an effective measure of correctly processing economic development to let it fit the national overall benefit and the long-term benefits and strengthening environmental management.Environmental Impact Assessment plays the influential role in a series of major decisions,such as Determination economic development direction,protection environment and so on.By Plan Environmental Impact Assessment,we can carry on the generalized analysis to the natural condition,the resources condition,the social conditions and the economic development in the planning region,we can grasp the resources,the environment and the social condition,makes the scientific decision and the plan To the development direction,develops the scale,the industrial structure and the industrial layout of this area.Plan Environmental Impact Assessment can instruct the region activity and realize the sustainable development.Because the related studies and literature about Risk Assessment which is a part of Plan Environmental Impact Assessment is very defective,this domain's research work is worth further developing.Currently,the work of Plan Environmental Impact Assessment Just started,and the related assessing and researching work still carried on.Region environmental protection consciousness still waited for further enhancing.The work about Plan Environmental Impact Assessment has not been taken seriously fully,and the research results are also few.As the important part of Plan Environmental Impact Assessment,Risk Assessment has not been requested in the Technical Guidelines for Plan Environmental Risk Assessment.So,the research about the application of Risk Assessment in Plan Environmental Impact Assessment is worth further developing.At the period of studying for the master's degree,I played a part in accomplishing the "Environmental Impact Assessment Report of Jiheng Circulation Economical Industrial Park Planning",and I did the deep research about the chapter of "Risk Assessment".This paper takes this Risk Assessment as the foundation.Through induction and deduction,I summarized the Original Achievement,and carried on coarse and shallow Inquisition and supplement to the application of Risk Assessment in Plan Environmental Impact Assessment.First of all,this paper introduced the background of researching Environmental Risk Assessment,Summarized the goal,the method and the significance,and proposed the innovation spot.Then it introduced the concepts,connotations and characteristics of Environmental Impact Assessment,Plan Environmental Impact Assessment and Environmental Risk Assessment.By citing examples which neglecting environment risk causes regional disasters and losses,this paper introduced Environmental Risk Assessment's status,function and state of play in our country.At the present,because the ministry of Environmental Protection hasn't issued the technical guidelines for Plan Environmental Impact Assessment in our country,this paper refers to the procedure in the technical guidelines for environmental risk assessment on Projects,unifies the characteristic of Plan Environmental Impact Assessment,summarized the assessing procedure,techniques and measures of the environment risk management in Environmental Risk Assessment.This paper this paper involves forecast patterns about Atmospheric and Surfacewater Environmental Impact Assessment,mathematical models about Hydromechanics and detonation injury and aiding methods of rowing statistical graph,determining destruction scope,and calculating risk probability and hazard index.Later;uniting the example of Jiheng Circulation Economical Industrial Park Planning,this paper carried on the concrete explanation.At last,this paper summarized the content,emphasized the importance of Plan Environment Risk Assessment, and indicated the direction of key research and work at present.
