山区小气候对大气污染扩散的影响

The influence of microclimate in mountain aneec on the diffusion of air pollution

根据武夷山脉及邵武市所处的地理位置，分析邵武市的气象特征，结果表明：在山区，由于大气各地局部增热（冷却）不均而发展起来的小规模的热力环流，也就是地形的热力作用所增强的山谷风环流，以及地形的动力作用对山谷风产生的犹流，均对大气污染的扩散有着紧密的关系。

According to the geographical position of Shao wu City and Wuyi mountain range. this paper analysis the meteorologiceal features in Shaowu and shows that: in mountain area.the heating power circlation resulted from dis-uniform air heating in every part.that is mountain valley wind circulation strengthened by topographic heating power and disturbed by topographic motiving power ralates to the diffusion of air pollution closely.
