区域环评中大气环境容量估算的研究进展

目前,在大气环境影响评价中,区域大气环境容量的研究是实施大气污染物总量控制的前提.文章综述了大气污染物区域环境容量的主要影响因素、用于其计算的空气质量模型以及大气环境容量研究的一般步骤.现阶段应用较广泛的大气环境容量的预测模型有A-P值法模型、箱模型、线性优化模型、ADMS模型及多种模型相结合的复合模式等,通过研究分析,提出了现阶段大气环境容量研究存在的主要问题及其有效的解决途径.

Progress on Studying of Atmospheric Environment Capacity in the Region Environment Impact Assessment

Recently,in the atmospheric environment impact assessment,the study of the atmospheric environment capacity is the precondition of carrying out total capacity control of the atmospheric pollutants.For the atmospheric pollutants'environment capacity of the area,the article summa- rizes the main effect elements of it,the atmospheric quality models used for computing it,and the usual proceed of computing it.At present,the models used at large involve A-P method model,the box model,the optimal linearity model,the ADMS model,and the complex models that are constituted by more than one single model.Through the analysis of the study,the article points out the problems of study on the atmospheric environment opacity, and also finds the solution of it.
