【摘要】 本文介绍SXVEQAS(山西大学环境质量评价系统)中污染源对大气环境质量影响模拟的数学方法。全文分为两大部分,第一部分为单污染源影响模拟方法,主要介绍长期平均浓度等浓度曲线与污染区划分的计算方法,并以岳南矿为实例说明。下文将介绍第二部分,介绍多污染源影响模拟的一些数学方法。它主要研究使用网格法进行对大气污染形势模拟、大气污染预报、等浓度曲线和污染区域划分计算的数学方法,这是区域性环境质量评价与环境规划中急待解决的关键问题。更多还原

【Abstract】 The article introduces the mathematical methods in simulation of the model of pollution sources′ impact on air environmental quality in SXU EQES (Shanxi University Environmental Quality Evaluation System). The whole article consists of two parts. The first part is about the simulating method of the single pollution source′s impact.lt mainly introduces the calculation method about equal concentration curve of long period averge concentration, and YUENAN mine is taken as an example to illustrate this. Then comes the second part, which introduces simulation of many pollution sources’ impacts.It tells us how to use net-square method to model and forecast pollution circumstances. It also showsthe calculation method of equal concentration curve of long period average concentration and methematical method in distributing different pollution districts. These are problems that demand quick solutions in environmental district evalution and environmental planning.更多还原
