Abstract: Based on the data of annual runoff of the Hotan River,the impact of climate changes and human activities on the variation law and its genesis were discussed by the wavelet analysis and the R/S analytical method.The result shows that the tendency of the annual runoff is decreasing with persistence to a certaian degree.The analysis of the influencing factors of the annual variation of runoff indicate that the variation of runoff in the mountain pass of the upper reaches is mainly affected by the temperature rise.The variation of runoff in the lower reaches,which afflux the Tarim River,is mainly affected by the human activities except the influence of precipitation decreasing,because of the quickening pace of human exploitation of the water and soil resources.

Key words: Hotan River, runoff changes, wavelet analysis, analysis of the R/S, climate changes, human activities
