摘  要:以黄山景区的地形、植被、坡度和降水等资料为基础数据,利用GIS技术,采用熵权法确定权重,再通过综合加权求和法对黄山景区的山洪灾害进行风险区划。结果表明,黄山景区的山洪灾害以中危区为主,约占景区面积的72%,山洪灾害高危区和低危区分别占景区的21%和7%;高危区分布于景区的中西部,由中部高危区和西南部高危区组成;中部高危区有北海景区和玉屏景区两大热点景区,存在较大的旅游安全隐患。应做好灾前、灾中、灾后的预防、抢救重建方面的灾害风险应急管理工作。Based on the data of topography,vegetation,slope and precipitation,the regional risk zonation of torrent disasters in Huangshan Scenic Area were determined by the comprehensive weighted summation method,entropy weight method and GIS.The results show that the torrent disasters in Huangshan Scenic Area are mainly in medium risk areas,accounting for 72%of the scenic area,and the high risk areas and low risk areas account for 21%and 7%of the total scenic area,respectively.The high risk areas of torrent disasters are located in the central and western part of the scenic area,which can be divided into high risk areas in the central part and high risk areas in the southwest part.In the central high risk areas,there are Beihai Scenic Area and Yuping Scenic Area,which have great potential tourism safety hazards.The emergency management of disaster risk should be done in prevention,rescue and reconstruction work before,during and after disaster.
