中文摘要：
根据实地考察和观测资料，对新疆头屯河流域不良地质现象分布特征进行分析。结果表明：头屯河流域不良地质现象主要发生在流域中游地带，出现时间的分布受降雨条件控制，集中出现在降雨期。不良地质现象受自然环境多因素的影响和制约，是地质、地貌、地表物质组成、地震活动、水文气象、植被条件以及人类活动等诸因素作用的结果。流域不良地质现象的发育，为流域河道来沙提供了大量的物质基础，根据流域自然环境和不良地质现象的活动分布状况，从生物、工程和社会3方面提出了防治措施。
英文摘要：
In this study, the characters of distributions of ill geological phenomena in the Toutunhe River basin were analyzed, based on the spot investigation and observed data analyzed. The results showed that ill geological phenomenon in the Toutunhe River basin mainly occurred in the middle reach of the river, the time distribution were controlled by the conditions of rainfall. The ill geological phenomenon were influenced by many natural factors, such as geology, landform, material composition, seismic activity, hydrometeorology, plant and human activities. The development of ill geological phenomenon in the river basin provided a mass of material elements, so it is tried to give some advices to prevent the ill geological phenomena, based on the natural environment and the condition of distribution of the ill geological phenomena in the river basin.
