杭州市区酸性降水现状分析

SOME ANALYSES OF ACID PRECIPITATION OF URBAN DISTRICTS IN HANGZHOU

中文摘要:

      我国酸雨主要发生在长江以南地区和西南地区,杭州是长江以南地区经常发生酸雨的城市之一。本文在单点降水酸度监测基础上,用一九八三年九个测点所监测的降水酸度资料,分析了杭州市区目前酸性降水的现状。初步得到一些有意义的结果。为今后进一步开展这方面工作提供参考。

英文摘要:

      The nine observation stations had been established to determied the acidity and some ions in the precipitation over urban area of Hangzhou during 1983.These deteminations show that the frequency of acid rain presence is 81.4%, the variation of pH value is 4.03-8.80 and the average of pH is 4.58.Occured acid rain is mostly in regions of pH 4.3-4.8.The acidity and frequency of precipitation are highest in industrial area of over urban. The concentration of some ions in snow is higher than rain.
