中文摘要:
      该文以遥感及GIS作为数据获取与分析处理的技术手段,以地质环境条件复杂程度,潜在地质灾害隐患点的分布、灾害点密度、灾害体规模、地质灾害危害程度等作为基本评价要素对五华县地质灾害危险性进行综合评估并分区,最终划定地质灾害危险程度高、中、低3个等级共12个亚区;即高危险区(ⅠA)有4个亚区,中危险区(ⅡB)有4个亚区,低危险区(ⅢC)有4个亚区。
英文摘要:
      Taking remote sensing and GIS as the technical means of data acquisition and analysis and processing, taking the complexity of geological environment conditions, the distribution of potential geological hazard points, the density of hazard points, the scale of hazard bodies and the degree of hazard of geological hazards as the basic evaluation elements, this paper comprehensively evaluates and divides the hazard of geological hazards in Wuhua County, and finally, delineates the high, medium and low hazard degree of geological hazards. There are 12 sub-regions:4 sub-regions in high risk area (Ⅰ_A), 4 sub-regions in medium risk area (Ⅱ_B) and 4 sub-regions in low risk area (Ⅲ_C). Through the extension of this evaluation and analysis, the practical significance of the comprehensive assessment method of geological hazard risk in other areas is discussed.
