Abstract:

 In order to eliminate the impact of urbanization on the ground temperature of old meteorological observation station，the　mean，variance and correlation of 0 － 20 cm synchronous ground temperature from January to December in 2012 in the old and new meteorological stations of Kangle were analyzed and tested by using mathematical statistic and F， T and t test methods，and the line regression equations of the obvious difference ground temperature between the old and new stations were fitted by using the least square method． The result showed that the difference of 0 － 20 cm ground temperature in the old and new stations was negative as a whole，that is　to say，the ground temperatures in the new station were higher than those in the old station，and the differences in most of months were　small． Although the data of ground temperature had a good continuity，the fluctuations of the difference between the old and new stations were large． The obvious ground temperature difference between the new and old stations in January and October appeared a significant linear correlation，and the ground temperatures between the revised data and the data of the new station were basic coincidence．
