摘要
以1986—2003年呼和浩特市河流水质监测资料为基础，选取高锰酸盐指数（CODMn）、五日生化需氧量（BOD5）、氨氮等指标，运用水质综合指数法，探究呼和浩特市地表水环境水污染的特点和变化趋势。结果表明，呼和浩特市地表水环境水质状况整体虽然有所改善，但污染依然严重；生活污染源、环保治理等已成为影响呼和浩特市地表水环境演化的新因素。
Based on data of river water quality monitoring of Hohhot from 1986 to 2003 and adopted with water quality comprehensive index method, the characteristics and change trend of surface water environmental pollution of Hohhot were exploited, through selecting indicators, such as COD, BOD5, ammonia and nitrogen. The result showed that the general trend of surface water quality of Hohhot was improved, but pollution was still serious, and the living pollution sources and environmental treatment had become the new factors influencing the evolution of surface water quality.
