| 摘 要： | 本文通过对广州市区雨水酸度的分析,认为广州是酸性基础甚强的城市,酸雨出现的频率为60%左右,并有冬春强,夏秋弱的季节变化趋势。指出逆温和微风等稳定天气条件是产生酸性降水的有利天气条件。对水样的化学分析结果可见,广州酸雨中SO4=为主要酸根,各类酸根的浓度变化受环境和人为因素的影响较大。阳离子浓度的强弱对市区酸雨起着重要的缓冲作用,在碱性污染源附近尤为明显。水化学分析结果表明局地污染源的作用是明显的,所以广州市区酸雨主要是由于本地大气污染所致。

| Abstract: | The acidity of precipitation in Guangzhou is studied.It points out that Guangzhou is acid-sensitive and the frequency for acid rain to take place is about 60 per cent in the urban area. Acidity of rain is strong in spring and weak in summer. Under stable weather conditions, such as inversion or breeze, acid rain is produced easily. Results of chemical analysis of rain sample show that effect of local pollution source is obvious on acid rain in the city. |
