摘要
截至2023年12月,佛山市三水区已发育地质灾害 123 处,地质灾害类型分为崩塌、滑坡、地面沉降、地面塌陷 4 种.通过野外调查、工程勘察、遥感解译等手段查明三水区各类地质灾害影响因素,建立地质灾害易发性评价体系,并采用加权评价模型完成三水区地质灾害易发性评价.结果表明:三水区地质灾害易发程度分为 9 个高易发区,面积 148.35 km2,占比 17.0%;10 个中易发区,面积 232.86 km2,占比 26.6%;10 个低易发区,面积 492.79 km2,占比56.4%.评价结果可服务于三水区地质灾害精准防控.
Abstract
As of December 2023,there are 123 geological disasters been developed in Sanshui District,Foshan City,which are divided into four types including collapse,landslide,land subsidence and land collapse.Through field investigation,engineering investigation,remote sensing interpretation and other means to identify all kinds of geological disasters influencing factors in Sanshui District,establish a geological disaster susceptibility evaluation system,and to complete the geological disaster susceptibility evaluation in Sanshui District using weighted evaluation model.The results show that the geological disaster susceptibility in Sanshui District is categorized into 9 high susceptibility zones,with an area of 148.35 km2,accounting for 17.0%;10 medium susceptibility zones with an area of 232.86 km2,accounting for 26.6%;10 low susceptibility zones with an area of 492.79 km2,accounting for 56.4%.The evaluation results can serve for the accurate prevention and control of geological disasters in Sanshui District.
