六枝特区地质灾害分布特征和孕灾环境分析OA

This paper systematically analyzes the distribution characteristics and disaster-prone environment of geological disasters.Through research,it is found that in Liuzhi Special District,geological disasters are mainly landslides and collapses,mostly of medium and small scales.In terms of temporal distribution,it is closely related to atmospheric rainfall,concentrating in the months of May to September annually,especially during the heavy rain period from June to August.In terms of spatial distribution,it shows a characteristic of being dense in the south and sparse in the north.The occurrence of geological disasters is influenced by multiple factors such as meteorology and hydrology conditions,topography and landforms,stratigraphy and geological structure,hydrogeology,and human engineering activities.Among these,rainfall is the main natural trigger factor,and mineral exploitation is the main human-induced factor.Based on comprehensive analysis,the author divides the disaster-prone environment into three grades and seven zones.The research results can provide a theoretical basis and scientific support for disaster prevention and mitigation,engineering construction planning,and high-quality economic and social development in Liuzhi Special Zone.
