Abstract:
Using the meteorological disaster loss data from 2004 to 2013,the distribution characteristics of the comprehensive losses for various meteorological disasters in China were analyzed.A comprehensive loss index for the meteorological disasters was built based on the non-dimensional and normalized methods.The results show that except the direct economic losses,the numbers of deaths and population affected by meteorological disasters,the area of crop failures and the percentage of direct economic losses to the gross domestic product (GDP) all decrease from 2004 to 2013.Rainstorm flood and drought are the main meteorological disasters that affect China.The number of deaths and direct economic losses caused by rainstorm and flood are the highest.The area of crop and number of population affected by drought are the uppermost.The influence of rainstorm and flood is more serious in the Yangtze River Basin.For drought,it is more severe in the South-west China,Inner Mongolia Autonomous Region and Heilongjiang province.The frequency of typhoon is the highest in the southeast coastal areas of China.The local strong convective disaster mostly affects North China and Huanghe and Huaihe river areas.The Yangtze River Basin often suffers the low temperature and freezing disasters.Generally,the comprehensive losses caused by various meteorological disasters are serious in the middle-east areas,especially in Sichuan,Hunan and Hubei provinces.
