基于距离函数的区域性暴雨灾害风险预估方法研究

Study on a Disaster Risk Prediction Method for Regional Heavy Rain Events based on Euclidean Distance Function

摘要: 以湖北省历史暴雨灾害资料为基础,筛选、确定暴雨灾害个例,采用正态概率密度函数、区间平移和欧氏距离函数等方法,构建湖北省5—9月区域性暴雨天气过程强度等级、可能产生的灾情损失值风险预估模型。应用结果表明,该模型对区域性暴

Abstract: The cases of torrential rain were chosen based on the history data of heavy rain disasters in Hubei Province.The probability density function of the normal distribution,the interval movement method and the Euclid
