The Study Of Index System Of Environmental Impact Assessment Of Planning

The two tides have occurred from 1940's on environmental problem, which took people bitter lessons and made people gradually know about the serious price of destroying environment. The promulgation of National Environmental Policy Act in the U.S. in 1969 established Environment Impact Assessment (EIA) system. In consequence, such a system was also approved in more than 100 countries like Sweden, Canada, Australia and Germany. After many years of study and practice of this issue, human beings gradually learned that traditional approach was faced with limitations in the process of its application. So it is necessary to establish and improve EIA system based on sustainable development. EIA targeting at sustainable development consists of 3 levels of macro, medium and micro impact appraisals. Within the system, appraisal targets like policies, plans, programs, and projects are located in different hierarchies, in which policies assessing environment are macroscopic, plans and programs are medium and projects are microscopic. Such EIA of different hierarchies shall be supplementary, coherent and avoid repetition.Environmental impact assessment of planning is the procedure of analyzing, forecasting and assessing the environmental impact that are likely to occur during weaving planning, because planning is put in practice. Scholars from home and abroad have done a lot of researches and fulfillment. However, we can always find that its work objective isambiguous and its theoretic support for indicators system is insufficient.Strategic Environmental Assessment (SEA) of regional plans is one category of SEA and the related researches are carried out primarily. In the SEA, it is urgent to develop a set of indicators to analyze and assess the plans.Indicators refer to signals reflecting complicated matters or systems, or information revealing features of a system or predicting future occurrences. By taking number as its language, it usually exhibits quantitatively general characteristics of certain social phenomena. Indicator of Environmental impact assessment of planning carries such characteristics as targeting at clients, linking to policy, communicating internally and quantification. The establishment of indicators system shall closely keep in accordance with science, feasibility, sustainable development, independence, relevance, hierarchy, regional policy maintenance, combination of static and dynamic indicators and measurability.The indicators for Environmental impact assessment of planning can be divided into key indicators and relevant indicators. Furthermore, key indicators can still be divided into, resource and environment indicators. Relevant indicators are composed of economic and social indicators. Hierarchy occurs on Indictors system of Environmental impact assessment of planning that can be provided into objective hierarchy, principle hierarchy and indictors hierarchy.Indicator system for SEA in Dominative detailed planning ofIndustry concentrates area of Changchun City Erdao borough is based on the principle of environmental impact identification and design of indicator system, and is quite applicable in terms of the acquisition of both indicator data, assessment criteria, and implementation of assessment.
