摘要
水城县位于贵州省西部乌蒙山区,区内山高坡陡谷深,自然地理及地质条件恶劣,地质灾害频发、易发。本文以水城县重点地区重大地质灾害隐患详细调查成果为依据,从自然因素和人类工程活动两大方面对地质灾害孕育背景及引发因素进行研究,通过对近年新增地质灾害隐患的统计分析,归纳总结出地质灾害隐患在时空上的分布规律及其主要影响因素,指出了水城县地质环境条件复杂是客观存在的,地灾防治工作的重点应放在降低外在因素对灾害的影响上。
Shuicheng county situated in Wumeng mountain area of west Guizhou with high mountains,steep slopes and deep valley,the geographic and geologic conditions are bad,the geologic disaster happened usually. In this paper,according to the important geologic disaster detailed survey of important areas of Shuicheng,the background and leading factors of geologic disaster are studied in natural factors and human activity,by statistic analyses of geologic disaster risk in recent years,the temporal-spatial distribution rules and influence factors are summarized,it indicated the complex geo-environmental condition of Shuicheng is objective,the key point of geologic disaster prevention is reduce the influences of external factors.
