| 摘 要： | 通过对吉林省８个代表城市１９９２－１９９７年大气降水观测数据的统计分析，对大气降水ＰＨ值的时空分异进行了探讨。结果表明：吉林省中西部城市大气降水基本呈中性；东部的图们，珲春两市大气降水酸化亚得，多年平均降水ＰＨ分别为５．１２和５．３８；全省碱性降水多集中在吉林市。

| Abstract: | Through statistical analysis on dada of atmospheric precipitation samples of 8 cities from 1992 to 1997,this paper deliberated on temporal and spatial variation of pH of atmospheric precipitation in Jinlin province,China.The results show that atmospheric precipitation of cities in Jilin province is basically neutral.However,a few of cities,Tumen and Hunchun,have serious acid precipitation with the peak pH values in winter and spring.The temporal and spatial variations of pH of atmospheric precipitation are affected by both local sources and peripheral sources,and are related to both natural and economic factors.Finally,corresponding treatments are put forward on acid atmospheric precipitation of cities in Jilin province. |
