摘要
近年来,洪水灾害的频发,对生态系统产生了巨大的危害。为防治洪水灾害的危险,采用地理信息系统(Geographic Information System,简称GIS)和层次分析法(Analytic Hierarchy Process,简称AHP)两者结合,并根据延边州的地形地貌、水文地质条件、土地利用等数据,选取降水、高程、坡度、土地利用、河流等五个影响因子,然后利用GIS对影响因子进行栅格数据分析,得到延边州洪水灾害危险性划分图。将该研究结论作为延边州防灾减灾工作参考。
In recent years,the frequent occurrence of flood disasters has caused great harm to the ecosystem.In order to prevent and control the risk of flood disaster,GIS and analytic hierarchy process are used in this study.According to the data of topography,hydrogeology and land use in Yanbian Prefecture,five influencing factors,such as precipitation,elevation,slope,land use and river,are selected,and then the grid data analysis of influencing factors is carried out by using GIS to get the flood hazard classification map of Yanbian Prefecture.The conclusion of this study can be used as a reference for disaster prevention and mitigation in Yanbian Prefecture.
