南宁市酸雨来源分析

The study on origin of Nanning acid rain

南宁市酸雨频率及降水酸度长期以来居高不下 ,控制酸雨污染已是南宁市“十五”环境保护工作的重中之重 .本文在全面分析南宁市酸雨现状及发展趋势的基础上 ,通过对典型大范围降水结合大气流场特征分析 ,定性确定外来源是南宁市酸雨的主要来源 ,并运用模型定量确定南宁市酸雨各来源所占的比重 。

The acid rain s frequency and acidity have been remaining highly fora long time in Nanning so it is imperative to control acid raid pollution in Ten- Five period.In this paper on the basis of thorough studies on current status and developing tendency of Nanning acid rain,external source was qualitatively verified as main sources of Nanning acid rain by analyzing representative large - scale precipitation combined with study on characteristic of atmospheric circumfluence,every source of Nanning acid raid was also quantitatively determined through models at the same time,so as to supply scientific testimonies for controlling and eliminating acid rain pollution.
