Exposure and vulnerability characteristics of typhoon disaster in Guangxi
Based on the data of typhoon disaster,population and social economy in Guangxi from 2001 to 2020,the exposure and vulnerability characteristics of crops,population and economy in typhoon disaster in Guangxi were statistically analyzed.The results showed that:(1)from 2011 to 2020,the annual average typhoon disaster-affected population,crop-affected area and direct economic loss in Guangxi decreased by 57.3%,6.7% and 1.7%,respectively,compared with the previous 10 years,but extreme disasters occurred from time to time.(2)The geographical variability of typhoon disaster exposure were large in Guangxi from 2011 to 2020.The areas of high annual average crop exposure were mainly distributed in central Guangxi,and the lowest in northwest Guangxi.The areas of high average annual population exposure were mainly distributed in densely populated urban centers such as Nanning,Liuzhou,Guilin and Beihai and southeastern Guangxi,and the lower in Northwest Guangxi.The distribution characteristics of economic exposure were similar to that of population exposure.(3)The multi-year average crop,population and economic vulnerability to typhoon disasters in Guangxi from2011 to 2020 were 4.4%,5.19% and 0.21%,respectively.The areas with the high vulnerability of crops and economy were distributed in coastal areas and Chongzuo City,and the areas with high population vulnerability were distributed in southern Guangxi.All of them were decreasing in 2016-2020 compared with 2011-2015.Therefore,coastal areas and Chongzuo need to focus on preventing typhoon disasters,improve disaster prevention and mitigation capabilities,and reduce disaster risks.
