摘要
以县域为研究单元,通过对2009—2020年广东省台风灾情数据的分析,结合降水数据、风场数据、地形数据、河网数据和统计年鉴等资料,研究了台风灾害时空格局特征。在此基础上,运用地理探测器方法研究了台风灾害的影响因素。结果表明,共有47个台风登陆或影响广东,其中21个超强台风造成的损失最严重,灾害损失严重地区主要分布在广东南部的湛江市。台风灾害致灾因子、孕灾环境因子和人类活动因子中,台风最大风速、3 d内最大降水量和距台风中心距离对受灾人口、死亡人口、受灾农作物和直接经济损失的影响最大。
Typhoon disasters have taken a heavy toll on casualties and property losses in Guangdong Province,China.Based on the historic typhoon disasters data from 2019 to 2020,wind field data,precipitation data,terrain data,river network,statistical yearbook and others,the spatiotemporal patterns are analyzed on the county scale.Besides,the influencing factors of typhoon disasters are also explored by Geodetector technique.The results show that there were 47 typhoons landfalling or affecting Guangdong Province,21 super typhoons of which caused the most serious losses,and the most serious region mainly located in Zhanjiang City.The maximum wind velocity,maximum three-day precipitation and distance to typhoon center are the three dominant factors that influenced the affected population,deaths,affected crops and direct economic losses.
