摘要
HJ 2.2—2008《环境影响评价技术导则:大气环境》规定大气环评工作采用估算模式(SCREEN3)来确定评价等级,而进一步预测模式AERMOD的实际预测结果与SCREEN3的估算结果并不完全一致。新一代估算模式AERSCREEN耦合了AERMOD的相关内核(AERMOD、AERMAP、BPIPPRM),能快速计算污染源在最不利的气象条件下的浓度结果。为了解不同估算模式的差异,采用平坦地形、不同下垫面、不同污染源参数条件下的案例,对比估算模式AERSCREEN与SCREEN3的计算结果,并分析估算模式与AERMOD预测结果的一致性。
According to ＂Guidelines for Environmental Impact Assessment-Atmospheric Environment＂（HJ2.2—2008）,the first step of atmospheric EIA is to determine the working grade of atmospheric EIA by a screening model.However,the results of the prediction model AERMOD were not consistent with the results of the previous screening model of SCREEN3 due to the differences in the data processing and degrees of complexity of applied diffusion theory.Including the relevant kernel of AERMOD,AERMAP,BPIPPR in AERMOD modeling system,the new generation estimation model AERSCREEN has the ability to predict the concentration results under the undesirable meteorological conditions quickly.To investigate the performance of different screening models,a comparison of the results by AERMOD,AERSCREEN and SCREEN3 of several scenarios of various underlying surfaces and source parameters has been conducted for the flat terrain.
