摘　　要：随着模型预测要求和模拟精度的不断提高,越来越多的建设项目在环评中使用Calpuff模式,该模式对地面气象资料使用和参数的设定比较复杂。实例模拟结果表明,地面站数量和部分气象参数的设定对预测结果的影响有限,在符合《环境影响评价导则大气环境》规定和模型输入需求的前提下,环评中对地面站点的数量要求不必过于严格,可视预测模拟精度要求适当调整。Due to the increasing requirements for model prediction and simulation precision,more and more projects are using Calpuff Model in EIA. Calpuff Model has more complex requirements for the use of ground meteorological data and parameter settings. However,the simulation results of real examples showed that the number of ground stations and some meteorological parameter settings had limited influence on the prediction results of concentration. Therefore,there is no need to be too strict on the number of ground stations in EIA,and it can be adjusted according to the precision requirements of prediction and simulation.
