摘要
五华区共查证崩滑流及地面塌陷灾害点60处,灾情堪称严重。基于ArcGIS平台,利用信息量法对全区地质灾害易发程度进行评价分区。高易发区面积31.35km2,中等易发区面积247km2,低易发区面积101.65km2。科学评估分区结果为政府进一步制定全区地质灾害防治规划提供科学依据。
60 disaster spots of collapse-slide flow and surface collapse have been confirmed in Wuhua district,which are very serious.Based upon the ArcGIS Platform,the assessment and zonation of disaster probability in this area are carried out with the information content method.The area of high probability is 31.35 km2,accounting for 8.25% of the whole area;that of middle probability is 247 km2,accounting for 65.35%;low probability 101.65 km2 accounting for 26.4%.This study result can provide the scientific base for making the plan of prevention and control of the disaster in this area.
