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。

Abstract

By using data of rainfall and hydrologic sediment

the characteristics of erosion and sediment generation at Toutui river watershed in the Xinjiang Uygur Autonomous region is analysed systematically.The majoy types of erosion in Toutui river watershed are erosions of water

wind

gravity and man-made accelerated which resulted by irrational soical and economical action of mankind

specially

water erasion is the primary type of it.The characteristic of water erosion there

is erosioning by water of melted glacier and snow.The erosion and sediment generation show obvious variational characteristic of time and space.The region in elevation of 800一1 400m

the vegetation is shorter there

it is the main region of sediment generation.The main period of erosion and sediment generation is in Period of month 5th一8th.
