摘要
指导环境影响评价的理论和技术方法要求具备较强操作性和实用性,鉴于实践中发现指导环评的相关技术方法存在一定的问题,这些给环评工作者在实际工作中带来了一定的困惑。通过对建设项目环境空气影响预测评价中存在的预测模式和方法两个常见问题进行了剖析,指出日均浓度预测方法和选取条件存在的不确定性及导则推荐的点源有风、小风模式预测结果的不连续性问题,通过提出上述问题为完善相关技术导则和方法修订提供可参考的依据。
The theory and the technical method of environment impact assessment request strong operation and usability, in view of the fact that technical method exists certain questions to bring certain confusion to the worker in the practice. The article analyzes the common questions of both the forecast pattern and the method which exist in project of the atmospheric environmental quality impact assessment, and points out uncertainty about the forecast method and weather conditions of daily average concentration, and discontinuous forecast results with the forecast pattern of spot source diffusion mode in the presence of windiness and light wind commended by technical guidance. It is expected to offer support for editing and consummating technical guidance and methods.
