摘要
本文根据我国水利部水文年鉴中的水质监测资料和全球水质监测计划中长江站的水质监测资料,对长江干流六十至八十年代水质变化的三个问题:河水碱度降低及Ca^(2+)和SO_4^(2-)含量增高与环境酸化的关系;Cl^-和氮化合物含量的增长问题;我国使用和停用六六六农药在长江水质监测中的反映等问题进行了研究和讨论.
Based on the analysis of water-quality data from wate year book and GEMS/WATER, three problems of water-quality trends in the mainstream of Yangtze river from 1960's to 1980's have been studied. They are: (1) the relationship between decrease of alkalinity, increase, Ca2+, SO42+ concentrations and environmental acidification; (2) increase of Cl-and nitrogen compound contents; (3) the response of water-quality to the use of benzene hexachloride in our country.
