摘要:

以深圳大鹏半岛为代表(大鹏炼油厂是该区域主要污染源),探讨了山地、海陆综合影响下之大气污染分析预测方法,提出了适用于南方沿海丘陵地段的大气环境预测模式,其主要内容包括两部分:(1)地形调整风场模式及风场特征;(2)复杂地形扩散模式。分析表明所得出的结果是比较合理的。

Abstract:

There is a long coastal line in South China,among which in hilly area,the complex effects of sea-land and terrain on air pollution are of common occurrenc,where the pollutants distribution is quite different from inland area.Dapeng Peninsula,Shenzhen,is a typical region of the area mentioned above. As a example, we discussed the problem of air pollution prediction ; put forward a new model for atmosphric environment forecast which mainly includes the following parts:(1)the non-uniform wind field model; (2)the dispersion model for coastal regions with complex terrain.The results of comparison between prediction and actual monitoring data show that the model is basically reliable.
