摘　　要：【目的】分析新疆水土流失的现状、类型及其成因的基础上对水土流失的时空分布规律进行研究,并提出相关防治对策。【方法】以查阅、收集和整理相关资料,采用野外调查与室内资料分析相结合的方法,对水土流失的时空分布规律的形成进行了探讨。【结果】在干旱少雨年份,风蚀沙化现象加剧;而在多雨年份,山地水力侵蚀加重;多雨多风年份,山盆结合部的水-风交错侵蚀加重。【结论】新疆地域辽阔,侵蚀类型多样,受环境条件、气候状况以及人类活动的影响。侵蚀强度,时空分布有一定规律可循。[ Objective] According to the presented general situation ,reasons and types of the soil erosion in Xinjiang, its spatial and temporal distribution are discussed and the soil erosion conservation strategies are put forward. [ Method ] In this paper, with the help of the abundant data obtained from the relative articles and Remote Sensing information and laboratory analyses, the causes of soil erosion and distribution are analyzed. [ Result] The results show that in the arid and little rain years, the wind and dust indulge in wanton massacre;In the more raining year, the mountain land is eroded by water power seriously. In the more minig and more wind years, the soil - water erosion become more and more serious. [Conclusion]In Xinjiang, the soil erosion has various types and is easily effeeted by the environment condition and climatic changes and human activities. The intensity and spatial and temporal distribution of the soil erosion in Xinjiang has a certain regularity.
