贵州某地区地质灾害发育特征的研究

Study on the development characteristics of geological hazards in a certain area of Guizhou Province

笔者研究的贵州地区某区域出露的地层,主要为青白口系与震旦系,其次为寒武系、石炭系、二叠系、三叠系、第四系。属典型的山区。发育的地质灾害主要有滑坡、不稳定斜坡、泥石流和崩塌,点多面广的特点。本文从地形地貌、地层岩性、地质构造、时间及人类活动等方面对地质灾害的发育特征分析,并对地质灾害发展进行影响分析,从而大致对本区域地质灾害易发程度分区,为今后的调查、防治与监测的提供基础依据。

The strata exposed in a certain area of Guizhou studied by the author are mainly Qingbaikou system and Sinian system,followed by Cambrian system,Carboniferous system,Permian system,Triassic system and quaternary system.It is a typical mountain area.The developed geological disasters are mainly characterized by landslides,unstable slopes,debris flows and collapses.This paper analyzes the development characteristics of geological disasters from the aspects of topography,formation lithology,geological structure,time and human activities,and analyzes the impact on the development of geological disasters,so as to roughly divide the prone degree of geological disasters in this region,and provide the basis for future investigation,prevention and monitoring.
