以气象站实测数据、DEM数据和统计数据作为数据源，100 m ×100 m的栅格单元作为基本的评估单元，结合区域灾害系统论建立了洪水灾害风险评估指标体系，并采用极差法、层次分析法、综合指数法和百分位阈值法等方法对长白山地区洪水灾害风险进行了评估。结果表明：长白山地区洪水灾害风险等级整体上西部较高东部较低，呈现出由西部向东部逐渐递减的趋势，其中临江市、抚松县和长白县的洪水灾害风险等级较高，和龙市和安图县的洪水灾害风险等级较低。
以氣象站實測數據、DEM數據和統計數據作為數據源，100 m ×100 m的柵格單元作為基本的評估單元，結閤區域災害繫統論建立瞭洪水災害風險評估指標體繫，併採用極差法、層次分析法、綜閤指數法和百分位閾值法等方法對長白山地區洪水災害風險進行瞭評估。結果錶明：長白山地區洪水災害風險等級整體上西部較高東部較低，呈現齣由西部嚮東部逐漸遞減的趨勢，其中臨江市、撫鬆縣和長白縣的洪水災害風險等級較高，和龍市和安圖縣的洪水災害風險等級較低。

We used the weather station observational data ,the DEM data and the statistical data as the data sources ,used the 100 m × 100 m grid cell as the basic unit of assessment to establish the flood disaster risk assessment index system based on regional disaster system theory ,and then used the range method ,analytic hierarchy process ,comprehensive index method and percentile threshold method to assess the flood disaster risk in Changbai Mountain area .The results showed that :the flood disaster risk grades of Changbai Mountain area are high in the west and low in the east in general ,and represent a gradual descending trend from the west to the east ,among them ,the flood disaster risk grades of Linjiang City ,Fusong County and Changbai County are higher ,and the flood disaster risk grades of Antu County and Helong City are lower .
