Abstract:

The thesis comprehensively discussed the variation tendency and influence degree of the extreme climate disasters in Shanxi Province, in order to research on the background of the frequent occurrence of the extreme climate disasters as well as their influence on natural ecosystem and social system. The extreme temperature data of 31 meteorological observations stations and the relative extreme climate disasters in Shanxi Province were applied to analyze the temperature variation tendencies by using tendency analysis, 5 points overlaping average and distance average analysis. The results showed that: based on the global warming, the tendencies of the extreme high temperature were increasing and the low temperature was decreasing. The extreme high temperature higher than 30℃ and 35℃ were increasing, but the extreme low temperature lower than 0℃ and -10℃ were decreasing especially the tendencies of the 0. Through comprehensive analysis of local climate changes of Shanxi Province, the author concluded that the rising of the extreme temperature was mainly due to the significantly increasing tendency effect of the temperature higher than 30℃.
