摘要
采用单因子污染指数法确定水质类别，用污染负荷系数法确定主要污染物，用污染变化趋势定量分析说明污染物变化趋势。根据1996～2007年地面水水质监测数据的统计、评价，论述了黄河兰州段水质现状，并对其水质污染的原因进行分析，从而提出相应的污染防治措施。结果表明，黄河兰州段水体以生物、有机类污染为主，无机、金属类污染次之，粪大肠菌群位于黄河兰州段之首；黄河兰州段水体总体污染变化呈下降趋势，下降趋势很显著。
The water quality categories were determined by single-factor pollution index method, the major pollutants weret determined by pollution load factor method, and the pollutant change trend was described by the quantitative analysis of pollution change trends. According to statistics and evaluation of the monitoring data of the surface water from 1996 to 2007 ,the water quality in Lanzhou section of Yellow River was analyzed in order to propos corresponding pollution control measures. Results indicated that the Yellow River water of Lanzhou section was mainly polluted by biological and organic pollutants, then followed by inorganic and metal pollutants and fecal coliform was the most in the Lanzhou section of Yellow River. The general water pollution in Lanzhou section of Yellow River presented a significant decreasing trend.
