摘要
用线性回归方法对云南省境内怒江流域1980年-2000年的水质状况及污染物输送量进行长系列趋势分析。怒江流域污染物入河量呈上升趋势，河流总体水质有下降趋势，主要支流水质下降程度高于干流，并结合面源对河流水质贡献率大的特点，提出流域面源污染防治对策及建议。
A long serial analysis on pollutant transportation volume and water quality situation from 1980 to 2000 of Nujiang basin is done by linear regression method. The results show that inflow volume of pollutants is raising and the whole water quality is decreasing. The water quality of the main subsidiary stream is falling greatly than Nujiang river. Countermeasures on controlling non -point pollution are pointed out based on the fact that non -point pollution source is of high attribution on polluting water.
