摘 要: | Using the adaptive
multiresolution data filter,the multihierarchical structure and jump features of climate changes in Sichuan
province during last 100 years are studied.The results show that(1)the air temperature variations in Sichuan basin can be
described as three hierarchiescold period before 1932,warm period from 1933~1965 and cold period after 1966.(2)The year 1949 is the jump point of cooling,and the temperature warming after
1987 is unstable.
