摘要: 根据2004-2008年辽宁22个酸雨监测站的统计资料,对近年辽宁酸雨的时空分布特征进行分析和探讨。结果表明:2004—2008年,pH年平均值范围为5.49—6.62,呈逐年降低、酸雨强度逐年增强的趋势;酸雨主要发生在大连、本溪县和丹东及兴城地区,其中大连酸度最强;建平县最弱;辽宁酸雨有明显的季节变化,pH值以夏季酸度为最强,春季为最弱,酸雨出现频率以秋季为最高,春季为最低。

Abstract: Based on the data from 22 acid rain monitoring stations from 2004 to 2008 in Liaoning province, the spatial-temporal distribution characteristics of acid rain were analyzed. The results show that the annual average of pH value ranges from 5.49 to 6.62 with a decreasing tendency. However, the acidity is an increasing tendency year by year. The acid rain occurs mainly in Dalian, Dandong, Xingcheng and Benxi country. The highest acidity appears in Dalian, while the lowest is in Jianping in the west of Liaoning province. The acid rain is of obvious seasonal variation in Liaoning province, and pH value is the highest in summer and the lowest in spring. Moreover, the occurrence frequency of the acid rain is the highest in autumn and the lowest in spring.
