我国台风风暴潮灾害损失的时空演变特征分析
Spatial-temporal characteristics of the typhoon storm surge damages in China
摘要
Abstract
The Mann-Kendall trend test,Pettitt mutation test,Morlet wavelet analysis and standard deviation elliptic spatial statistics were used to analyze the spatial-temporal distribution and evolution trend of storm surge disaster damages in China.The results show that during 1989 and 2018,the frequency of storm surge disasters increased while the fatalities and direct economic losses decreased.The mutation points of death population are 1999 and 2009,thereafter the death population shows an accelerating descending.The direct economic losses show an accelerating descending since 2006,relating to the developing of the national disaster prevention and reduction policy.The frequency of storm surge disaster damages shows significant periodic fluctuation of 2 years and 8 years.The frequency of death population is similar to that of storm surge disaster damages,but the main periodic fluctuation is not significant.Direct economic losses are more complex than fatalities and frequency fluctuations,with nested characteristics of multiple main periods between 2 and 8 years,which are significant for 2 and 8 years and insignificant for 3 to 5 years.The damages caused by storm surge and frequency are the most serious in the southeast coastal areas of China.In the past 30 years,areas with high storm surge frequency has shifted to the southwest and become more concentrated.Both the death(missing)population and the direct economic losses show aggregation phenomenon during 1999-2008.There is no significant shift in fatalities overall,and the direct economic losses show southwest transformation.关键词
