规划项目大气环境影响评价要点及案例研究

由于规划项目涉及面广、不确定性强、行业多样等特点，目前还没有针对规划环评的通用方法。虽然很多适用于建设项目环境影响评价的方法可以直接用于规划环评，但二者之间仍存在着很大的不同。结合规划项目的环境影响评价特点与评价要求，参考国内现有行业标准规范与新发布的大气评价导则技术要求，提出了规划项目大气环境影响评价的基本工作流程和4个工作要点，并通过具体案例应用，分别从基础资料收集与分析、环境影响预测方案制定、规划方案的比选及环境承载力的测算给出具体说明与实施方法。通过预测评价分析及方案比选，对规划选址、发展规模、规划布局、产业结构以及区域规划发展方式等进行综合分析，最终针对规划项目的污染控制及规划方案提出调整建议，为今后规划环境影响评价工作提供依据和技术参考。

ESSENTIALS AND CASE STUDY OF ATMOSPHERIC ENVIRONMENTAL IMPACT ASSESSMENT FOR PLANNING PROJECT

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
