Study On The Environment Access And Its Assessment Technical System

For a long time,China has continued with high input,high consumption,high emission,low efficiency is characterized by extensive economic development model,leading to high Gross Domestic Product(GDP)growth,but also led to the degradation of ecological functions,environmental quality deterioration,resource constraints tightening and other issues.At present,our country has entered a period of environmental risk and environmental pollution problems,the development of environmental problems caused by the past has not yet been fundamentally resolved,the new environmental problems have followed.Facing the new situation of environmental protection,the traditional environmental management system,which is dominated by the end of pipe control can’t meet the needs of the current environmental protection.We need introduce new environmental management methods.Environment access is one of the important tools of preventing environmental pollution and ecological damage from source,which is undoubtedly an important complement and improvement to the existing environmental management tools.Unfortunately,there is still a large shortage in the theoretical preparation and method system of environment access,such as lack of a clear definition,the indicators of the system is not uniform,technical system is not mature and so on.First,in this thesis,we start from the economic development and environmental effect,explore the theoretical system of environment access based on the literature search,trace its theoretical basis and legal basis,define the "environment access",analyze the environment access Characteristics,connotation and function;in addition,the relationship between Environmental Impact Assessment,similar concepts and environment access has been discussed,and then we have initially built the theoretical system of environment access,which would provide the theoretical basis for further research.Secondly,based on the previous research results and study of the theoretical system of environment access,we put forward the definition,basic framework,the principles,steps and requirements of environment access,and then build the comprehensive evaluation indicator system of environment access based on FM and AHP.The indicator system can not only filter out the projects which fail to meet the access requirements,but also quantify the comprehensive level of project.In addition,this thesis also put forwards the practical working-procedure of comprehensive assessment for environment access.Finally,this thesis applies the theory and methods that we study before to the Shishi Marine Biotechnology Park and its key industry,sets up the environment access conditions of the park and industry,builds the corresponding comprehensive evaluation indicator system and then the initial screening and comprehensive evaluation on three enterprises A,B and C which are going access to the park are given,according to the basic working procedures.The initial screening result shows that the enterprise C has been eliminated from the primary screening of environment access,because it fails to meet the industrial environment access conditions.A and B enter the comprehensive evaluation procedure.The comprehensive evaluation result shows that A and B are 0.91 and 0.94 respectively,both of which can meet the environment access conditions and have a highly comprehensive level of environment access.In addition,the environment result shows that firm A has a low score in terms of resource utilization and is the underlying reason for its overall score below B.The significance of this thesis is:First,to further clarify the definition and connotation of environment access,enrich and improve the environment access system of the theoretical system;the second is to build a basic framework for environment access,propose the practical working-procedure of comprehensive assessment,improve the environment access method system,provide reference and support forenvironmental management and project decision making.
