摘　　要：根据黔中清水河的普渡桥、水口寺、花溪3个断面2008年的监测数据,选用了9个与水质相关的参数,采用模糊数学的方法对贵阳市清水河的水质进行综合评价。结果表明:普渡桥和水口寺两个断面的水质全年较差,花溪断面的水质在平水期和枯水期良好,但丰水期稍差,有轻微的污染。For Qingshui River in Guiyang City, from the monitoring data collected in 2008 at three cross--sections of Pudu Bridge, Shuikou Temple and Huaxi, nine kinds of relevant parameters were selected, based on which a comprehensive water quality assessment was conducted with fuzzy mathematics, showing that water quality is relatively poor all the year round at two cross-sections of Pudu Bridge and Shuikou Temple; while water quality is fairly superior in normal and dry periods, a little poorer with slight pollution in high-flow period at Huaxi cross--section.
