利用地理加权回归(GWR)方法,引入地理空间要素,对台风经济损失的空间波动趋势进行分析.研究了台风登陆次数、最大过程降雨量、中心最大风速、数字高程(DEM)、人口、GDP、可用耕地等气象因素和社会经济因素与浙江省台风灾害直接经济损失的关系,总结出浙江省台风直接经济损失存在由北向南、由西向东逐渐增加的趋势,可以为台风风险管理工作提供一定的辅助决策依据.
Geographical weighted regression (GWR) was used to analyze the space wave trend of economic loss due to typhoon by introducing geo-spatial elements. Meteorological and socio-economic factors such as typhoon landing number, process maximum rainfall, central maximum wind speed, DEM, population, GDP, available arable land, were correlated to direct economic losses due to typhoon in Zhejiang province. North-to- south, west-to-east increases in direct economic loss were found. This would provide some basis for decision making in typhoon risk management.
