河南省主要工矿城市酸雨地理环境背景的调查研究

作者在重点调研了河南省九个处于不同地貌、气候、土壤类型区的工业和矿业城市后,发现处于该省中部地区山前平原的工业重镇郑州市、处于豫西山地缘山前平原的煤城平顶山市以及南阳盆地区工业重镇南阳市酸雨出现的频率较大,且较严重;处于豫北太行山东麓的山间小盆地中的两个煤城——鹤壁和焦作酸雨极少出现洛阳、新乡市则偶有出现.到1987年为止,开封和安阳等市尚未监测到酸雨现象. 调查表明,尚未发现酸雨对水生生态系统和陆生生态系有不良影响.但1987年郑州地区发生的严重树木虫害,据重庆市监测部门反映,恐与酸雨有关,值得研究;冬季,郑州市有雾且有烟尘弥漫不宜扩散,人眼有刺疼感.尚须继续深入探讨.

PRELIMINARY STUDIES ON ACID PRECIPITATION IN THE PRINCIPAL INDUSTRIAL AND MINING CITIES IN HENAN

Nine observation stations in Henan had been investigeted in order to have a better unberstanding of the acidity of precipitation .In this paper the influences of geographical enviroments, the distribution of pollutants and its relation to the activities of weather systems and climatic factor:conerned had been disacussed . Investigation based on the data collected indicates that acid rain had already come into existence in a good part of middle and southern Henan Among there cities the frequency of lower pH value in Zhengzhou,Pingdingshan, or Nanyang is higher than that in Hebi, Xingxiang or Jiaozuo.
