四川攀枝花小河流域地质灾害发育分布规律浅析

小河流域地处四川省攀枝花仁和区境内,地势南高北低,山脉走向近南北,岭谷相间。总体为中-大起伏中山地貌,较复杂的地形为滑坡、崩塌、泥石流的发生提供了空间,流域内地质灾害的发生一定程度影响了当地经济的发展。本文通过对区内23处地质灾害点的分析,讨论了流域地质灾害的主控因素及发育、分布规律,为科学合理地评价预测地质灾害的发展趋势与可能造成的危害提供参考资料。

ANALYSIS ABOUT THE DEVELOPMENT AND DISTRIBUTION OF GEOLOGICAL HAZARDS IN THE PANZHIHUA SMALL RIVER WATERSHED OF SICHUAN PROVINCE

The Small River watershed is located in Sichuan Province,Panzhihua Renhe Dis-trict territory,the terrain North is low,mountains to nearly North-South,ridge and valley. The physiognomy is medium-large undulate of medium mountainous region.the more com-plex terrain for the landslide,rockfall,debris flow to provide a space,the occurrence of geo-logical disasters in the basin to a certain extent affected the development of the local econo-my.In this article,through analysis of area 23 geological hazard of the main control factors and development,dstributin,scientific and reasonable evaluation may cause harm to provide reference data for prediction and trend of the development of geological disasters.
