Abstract:

There is currently a lack of general method for assessment of environmental impact for planning，mostly because of the wide range of projects，high level of uncertainties，and the diversity of industries involved.Although many of the methods that are used in environmental impact assessment for construction projects can also be used for planning，great difference exists between the two.This work is based on analysis of characteristics and requirements for planning project，in specific reference to industrystandard to domestic and guidelines for atmospheric environmental impact assessment requirements.We proposed a general working scheme and four key elements.Through some case studies，we illustrated collection and analysis of basic information，scheme making of environmental impact assessment，scheme comparison of planning，and calculation of environmental capacity.Through the comprehensive analysis of the plan selection，site selection，scale of development，planning layout，industrial structure and regional planning development，proper suggestions of planning project and pollution control for the planning were presented.This will give a technical reference to the atmospheric environmental impact assessment for planning project
