江苏省酸雨污染十五年趋势分析

根据江苏省的酸雨监测资料,对该省酸雨污染现状及“七五”末以来的变化趋势进行了分析,结果表明:淮河以南酸雨污染普遍重于淮河以北地区;“七五”末以来酸雨频率有降低的趋势,但降水酸度并未减弱;降水组份中,硫酸根离子当量浓度仍占首位,酸雨带来的污染和生态破坏未得到明显减轻。

Trend Analysis of Acid Rain Pollution in Fifteen Years for Jiangsu Province

Present distribution and changing trend of acid rain from 1989 to 2003 was discussed on the basis of monitoring data of acid rain in some cities of Jiangsu. Results showed that acid rain pollution in areas southern to Huaihe River was generally more severely than that to the north. Although the occurrence ratio of acid rain showed some decrease since the end of seventh five-year plan period, pH remained and equivalent concentration of SO{2-}-4 still occupied the primacy in the rain composition. Pollution and eco-destroy resulted from acid rain were not mitigated evidently.
