微风时局地大气扩散及SO2浓度分布的初步研究

A PRELIMINARY STUDY ON LOCAL ATMOSPHLRIC DIFFUSION AND SO2 CONCENTRATION DISTRIBUTION UNDER BREEZECONDITIONS

摘要:

本文利用微风时的定容球资料,计算了微风时南京大厂地区的扩散参数,并与兰州等地的扩散参数作了对比。还分别用两组不同的点源、面源公式,计算大厂地区在微、静风条件下SO₂的瞬时浓度分布。揭示了在微、静风条件下大厂地区容易出现污染的地域,为该地区的建设、规划及环保工作提供参考依据。

Abstract:

The atmospheric diffusion parameters in the Dachang area of Nanjing are calculated using tatroon data under breeze conditions and compared with those in the city of Lanzhou. Calculation is also performed of khe SO₂ instantaneous concentration distr ibution in the area under breeze and calm conditions with two sets of formulas of point source and area source respectively. It is found that some places in the area are subject to pollution. This provides useful criteria for construction planning and environmental protection in the area.
