中文摘要:
      山洪灾害严重制约着山地旅游景区的可持续发展,其风险区划对景区灾害防治具有重要意义.本文以庐山景区为例,通过调研、数据采集与分析,构建了景区山洪灾害风险评价体系,采用层次分析法对景区山洪风险进行了区划.研究结果表明:以汛期多年月平均降雨量、最大24h降雨量、水系缓冲区、坡度、坡向、高程、岩土体类型、断裂构造、植被覆盖指数、灾点密度等10个指标作为危险性评价指标,以旅游景点、上山道路、山顶公路、旅游线路、建筑物等5个指标作为易损性评价指标,形成了山区旅游景区山洪灾害风险评价体系;采用层次分析法获得了各评价指标权重,基于ArcGIS对评价指标进行空间叠加分析计算,得到了庐山风景区山洪风险区划分级图.经验证,该区域风险区划结果与实际调研数据吻合;研究区域中、高风险区面积占比约16.50%,低风险区占比约39.01%.研究结果为该区域山洪灾害防治提供数据支持,也为其它山地旅游景区山洪风险等级划分提供借鉴.
英文摘要:
      Mountain flood disasters seriously restrict the sustainable development of mountainous tourism destination,and it is important implication that that regionalization of mountain flood disasters risk can prevent and control the disasters.This study carried out the risk assessment system of mountain flood disaster through investigation,data collection and analysis in Lushan mountain tourism destination,and divided the risk of mountain flood by Analytic hierarchy process(AHP)method.The results show that the ten indexes of flood season(e.g.Average monthly rainfall in flood period,24-hour maximum rainfall,water buffer area,slope,slope direction,elevation,soil and rock types,fracture structure,vegetation coverage indexes,disaster point density,etc.)and the five risk assessment indexes(e.g.the tourist attractions,mountain roads,mountain top roads,tourist routes,buildings)are taken as risk assessment indicators.A risk assessment system of mountain flood disaster was formed in Lushan mountain tourism destination.The weight of each index was obtained by AHP method.The spatial superposition analysis and calculation of assessment indexes was carried out by ArcGIS software.The level map of mountain flood risk area was obtained.The results of risk division were in accordance to the actual investigation data.The area of middle and high risk areas accounted for about 16.50% and that of low risk areas was about 39.01% in Lushan mountain.The results provide data support for the prevention and control of mountain flood disaster,and also provide the reference for other mountain tourism destinations.
