| 摘 要： | 介绍了作者设计的计算复杂地形下大气污染物长期平均浓度的有限差分模式.模式输入资料为风速风向和稳定度的联合频率、源资料、GTOP30(30 s地形资料,可免费获得)地形资料,比高斯模式只增加使用了GTOP30地形资料.用该模式计算了古交2005年二氧化硫(SO2)的地面浓度分布.结果表明,运行时间可以接受,算例用时2.5 min.得到的浓度分布与直观认识一致.对比监测值,显示计算值与监测值比较吻合.

| Abstract: | The Gaussian model are usually utilized to calculate the long-term average pollutant concentration distribution in Environment Planning or Environment Impact Assessment,but the complex terrain is considered simple in the Gaussian model and the results are not very satisfied.A Finite Difference Methods model for calculating the long-term atmospheric pollutant concentration in the complex terrain was introduced.The input data of the model are the union frequency of the wind speed,wind direction and atmospheri... |
