【摘要】 为分析"9·7"地震贵州震区区域地质灾害的风险程度,采用模糊层次综合评价的方法,在全面统计分析研究区基础地质环境资料和地质灾害数据的基础上,开展基于GIS技术的地质灾害风险评估。评估结果根据风险值划分为极高风险区、高风险区、中风险区和低风险区四个等级区域,经与实际情况对比,具有较好的一致性,所得成果可为该区域地质灾害防治工作提供借鉴和帮助。更多还原

【Abstract】 In order to analysis the risk degree of regional geologic disaster,the FAHP method is used and on the basis of overall study the basic geo- environmental information and geologic disaster data in the target area,the geologic disaster risk is estimated by GIS technology,According to the risk value,the results are divided into: very high risk area,high risk area,intermediate risk and low risk area,this result is consistent with the reality and can be used for geologic disaster prevention in this area.更多还原
