摘　　要：泥石流堆积物的粘粒部分具有明显的物理化学活性 ,在一定程度上影响和制约了泥石流的发生和发展。本文通过实验测定了两条沟粘粒的化学成分 ,对两条沟的粘土矿物组成做了初步分析。The clay grain of dedris flow's deposits has physical and chemical activity obviously. Which effects happening and development of dedris flow in a degree .In this paper. the chemical compound of clay grain in two ravines has been tested and the composition of clay minerals has been analyzed preliminarily.
