摘要
黄河水体污染加剧黄河水资源的短缺情势。本文根据1992年～1999年监测资料对黄河干流水质级别以及溶解氧、氨氮、高锰酸盐指数和BOD5等4种典型污染物的时空变化进行评价,分析产生这些变化的原因,揭示了黄河干流多年来水体污染的时空变化规律。最后以1998年2月和8月为例,对干流各站点的水质水量进行联合评价。
Water pollution has deteriorated the water quantity available. Based on the monitor data of water quality during 1982～1999, the spatio-temporal changes of water quality levels and four typical contaminations, for example DO, NH_3-N, index of Permanganate and BOD_5, are analyzed, and some reasons are brought forward, then the rules of spatio-temporal changes of water pollution during 1982～1998 have been found. At last, taking examples of water in Feb. and Aug. of 1998, the joint assessment of water quality and water quantity in the stations in main channel of the Yellow river has been maken.
