摘要
本文对1985年至1994年监测的强酸雨资料进行研究和分析,并与一般酸雨进行对比。结果表明,本地的一般酸雨出现较为频繁;强酸雨出现增多;四季中强酸雨频率各不相同,秋季最高,夏季最低;强酸雨的酸沉降量正在逐年增加;强酸雨的电导率较高,电导率和pH间呈现高度显著的负相关;强酸雨的降水量一般较小,并与pH间显现非常显著的正相关;
In this paper, the data of the strong acid rain from 1985 to 1994 is analysed, and compared with the common acid rain. The results show that the state of the common acid rain happened frequently. The numbers of the strong acid rain are increasing. The frequency of the strong acid rain differed with various seasons, the highest in autumn and the lowest in summer. The amount of the acidic deposition of the strong acid rain is increasing year after year. The annual average of conductivity in the strong acid rain is higher than that in the common acid rain. The negative relationship between conductivity and pH in the strong acid rain is very clear. The rainfall amount of each strong acid rain is usually lower than that of each common acid rain. The positive relationship between rainfall amount and pH is highly notable. The concentration of each ion in the strong acid rain is higher than that in the common acid rain.
