四川省屏山县地质灾害分布及发育特征研究

Study on distribution and development characteristics of geological hazards in Pingshan County of Sichuan Province

屏山县位于四川省南部边缘,境内山峦起伏、地形崎岖、沟谷狭窄、斜坡陡峭,出露地层复杂多样,构造复杂、断裂发育、岩层破碎,地质环境相对脆弱,在降雨及人为活动下,极易诱发地质灾害。此次研究的目的是:通过收集近年来屏山县境内的地质灾害的变化及分布情况,利用MapGIS及Origin软件对发育各类地质灾害的斜坡坡向、坡度、高程等诱导因子进行统计分析,得出屏山县境内的地质灾害在时间及空间上的分布规律及发育特征。

Pingshan County is located in the southern edge of Sichuan Province.It has undulating mountains,rugged terrain,narrow gullies and steep slopes.The exposed strata are complex and diverse,with complex structures,fracture development,broken rock layers,and relatively fragile geological environment.Under rainfall and human activities,it is easy to induce geological disasters.The purpose of this study is to collect the changes and distribution of geological disasters in Pingshan County in recent years,use MapGIS and Origin software to analyze the slope direction,slope,elevation and other inducing factors of various geological disasters,and get the distribution rule and development characteristics of geological disasters in Pingshan County in time and space.
