| 摘 要： | Based on the monthly mean temperature, the changing processes and tendencies of temperature during1951 -2000 in Jilin Province, which is in Northeast China, are analyzed. And the spatial characteristics of the changeare submitted. In the past 50 years the temperature of Jilin Province was increasing just like the other areas in the world.Since 1990, the increasing of temperature has been more obvious than that in the previous 40a. From the west to theeast, the province has larger temperature rising. According to Principal Component Analysis (PCA) of temperature field,Jilin Province is divided into 3 regions and the degree of becoming warmer is different from region to region. During theperiod of 1951 to 2000, the annual temperature in Jilin Province has been rising, so has the temperature in winter andsummer. The average temperature in the 1990s was 0. 5 - 2. 0℃ higher than that in the 1950s. From the west to theeast, the increasing of temperature became smaller.

| Abstract: | Based on the monthly mean temperature, the changing processes and tendencies of temperature during1951-2000 in Jilin Province, which is in Northeast China, are analyzed. And the spatial characteristics of the changeare submitted. In the past 50 years the temperature of Jilin Province was increasing just like the other areas in the world.Since 1990, the increasing of temperature has been more obvious than that in the previous 40a. From the west to theeast, the province has larger temperature rising. According to Principal Component Analysis (PCA) of temperature field,Jilin Province is divided into 3 regions and the degree of becoming warmer is different from region to region. During theperiod of 1951 to 2000, the annual temperature in Jilin Province has been rising, so has the temperature in winter andsummer. The average temperature in the 1990s was 0. 5-2. 0℃ higher than that in the 1950s. From the west to theeast, the increasing of temperature became smaller. |
