摘要
本文论述了川西北山地泥石流的分布规律、类型、规模及危害状况,分析了该区域形成泥石流和因泥石流造成水土流失的主要原因。通过对该区域主要泥石流的活动状况的分析,进一步研究了泥石流在侵蚀、搬运和堆积过程中造成水土流失的机制;并在此基础上对泥石流防治工程的拦蓄泥沙、稳定沟床和保护山坡等水土保持功效进行了比较详细的分析和研究。
This paper deals with the distribution laws, types, scales and disastrous state of debris flow in mountain areas of Northwest Sichuan and also analyses the main cause of debris flow and soil and water erosion caused by debris flow in this region, Through the analysis of the activities of main debris flows in this region, this paper further studies the mechanism of soil and water losses in the process of erosion, transportation and sedimentation of debris flow, on Lhe basis of which, this paper also deals in detail with the effects of soil and water conservation of retraining sediments by debris flow controlling projects, stablizing gully beds and protecting mountain slopes.
