摘　　要：阿克苏卡尔斯亚沟位于阿克苏市温宿县北部,由山区+山前洪积平原河沟组成大规模泥石流,属典型干旱河谷区泥石流。该沟多次发生泥石流造成较大损失。为查明卡尔斯亚沟泥石流发育特征,2020年中央财政出资开展专项勘察。通过野外调查和测量,查明新疆阿克苏卡尔斯亚沟泥石流灾害地质环境、分区特征、形成条件,划定泥石流危险区范围,估算泥石流峰值流量,预测发展趋势。为防治工程设计、施工提供依据。Aksu Karsiya gully is located in the north of Wensu County,Aksu City.It is composed of a large scale debris flow in the mountain area and the river gully in the foreshore flood plain,which is a typical arid debris flow.Debris flow occurred several times in the ditch,causing great losses.In order to find out the development characteristics of debris flow in Karsiya Ditch,the central government funded a special investigation in 2020.Based on field investigation and measurement,the geological environment,regional characteristics and formation conditions of debris flow disaster in Karsiya Valley,Aksu,Xinjiang were ascertained,the danger area of debris flow was delimited,the peak flow of debris flow was estimated,and the development trend was predicted.It provides the basis for the design and construction of prevention and control engineering.
