| 摘 要： | 通过对南京江北区降水酸性及成分进行了全面系统的测定和分析,发现南京江北酸雨大大重于市区,并具有秋高春低,雨水离子浓度高,电导值大,强酸度与高发率同时出现等明显分布特征。气象条件影响主要表现为:大气降水量、气温和相对湿度与酸雨pH和电导值呈反相关,与酸雨频率呈正相关;大气压强与酸雨pH和电导值呈正相关,与酸雨频率呈反相关;风向风速对酸性污染物输送具有明显的引导作用;冬春季节沙尘和灰霾天气入侵对酸雨具有减缓效应。

| Abstract: | A study was conducted fully and systematically by monitoring and investigating the acidity and chemic compositions in the north bank of Yangtze River,Nanjing.Result showed that the acid rain of north bank of the Yangtze River is more heavy than urban area.The character of acid rain occurrence frequency is the highest in autumn and lowest in spring.There are high concentration of ions and high electrical conductivity.The top acidity and frequency occur simultaneously.Results showed that unlike baric analysis... |
