以1989 - 2001年通过盘江桥、高车断面的输沙量资料，分析北盘江流域的水土流失状况。
Based on the runoff and sediment transport data obtained at Panjiangqiao and Gaoche cross-sections from 1989 to 2001 the soil loss in the Beipanjiang basin is analyzed.
结果表明：流域北部的环江上游、合水川与汭河的径流量和输沙量以及土地覆被空间格局分布差异显著；
Results show that the visible difference of runoff yield and sediment yield and land cover pattern were found in the up of Huanjian, Heshuichuan and Ruihe.
流域植被度增大，可降低洪水径流总量和输沙量，显著削减洪峰流量，且减沙效益大于减水效益。
The benefit of sediment reduction is greater than that of runoff reduction with increase of vegetation.
结果表明：泾河流域近50年来的输沙量略有下降，而径流量减少比较显著；
Results show that sediment yield decrease slightly but runoff yield increase obviously of Jinghe watershed nearly 50 years;
河流输沙量的变化受流域降水和下垫面影响很大。
The variation of river sediment load is considerably affected by rainfall and underlying surface.
结果表明：不同大气环流模式对该流域降水量模拟结果不同，导致未来气候条件下径流和输沙量的预测也存在一定差异。
The results showed the ability of simulated data varied by different GCMs. It led to the difference of estimated runoff depth and sediment discharge.
