摘要
依据流域内降雨及水文泥沙资料，对新疆头屯河流域侵蚀产沙特征进行了系统分析。结果表明：头屯河流域侵蚀产沙类型较为复杂，主要侵蚀类型有水蚀、风蚀、重力侵蚀及人类不合理的社会经济活动所引起的人为加速侵蚀，尤以水力侵蚀为主。该流域水蚀的特征是冰川融雪水侵蚀的存在，流域侵蚀产沙具有明显的时空分异特征。在空间上具有明显的垂直分异规律，海拔为８００～１４００ｍ，植被较差，是该流域主要产沙区，在时间上亦表现出相对明显的分异特征，年际侵蚀产沙差异较大，年内月变化规律相对明显，每年５～８月份为侵蚀产沙最为集中的时段。
By using data of rainfall and hydrologic sediment,the characteristics of erosion and sedi-ment generation at Toutui river watershed in the Xinjiang Uygur Autonomous region is analysedsystematically. The majoy types of erosion in Toutui river watershed are erosions of water,wind,gravity and man-made accelerated which resulted by inrational soical and economical action of man-kind,specially,water erasion is the primary type of it.The characteristic of water erosion there,iserosioning by water of melted glacier and snow. The erosion and sediment generation show obviousvariational characteristic of time and space. The region in elevation of 800～1400m,the vegetationis shorter there,it is the main region of sediment generation. The main period of erosion and sedi-ment generation is in Period of month 5th～8th.
