摘  要:
本文从贵州西部环境角度,对贵州西部泥石流发生的现象和规律进行分析研究,认为:贵州西部泥石流的发生是由于贵州西部地区降雨集中、山高坡陡、地表破碎、地质条件复杂、土地垦殖指数过高、森林被覆率低下所引起。并指出在如此环境条件下,只有降低垦殖指数、增加森林被覆率才能有效地防治和减少泥石流的发生和发展。

摘  要:
In view of the environment in the western part of Guizhou Province, this paper deals with the phenomenon and law of occurence of debris flows in the westrn part of Guizhou Province. It is considered that the occurence of debris flow in the western part of Guizhou is mainly due to concentrated rainfall, high mountains with steeper slopes, broken land surface, complicated geological conditions, over land reclamation and cultivation indexes and low forest covering rate. In this way, this paper points out that only by reducing land reclamation and cultivation indexes and increasing forest covering rate, can the occurence and development of debris flows be effectively checked and diminished.
