Abstract: Based on 0 cm and 20 cm monthly average ground temperature and air temperature from 68 meteorological stations in Zhejiang Province from 1951 to 2018, and the annual average temperature for one hundred years at Hangzhou and Wenzhou stations, the 0 cm and 20 cm annual average ground temperature in Zhejiang Province from 1905 to 2018 were established by using the method of global correction of local station observations (GAoSV). The spatialtemporal characteristics of ground temperature at a century scale were analyzed through Morlet wavelet analysis, MK test and other climatic statistical diagnosis methods. The results are as follows: (1) The climate tendency rate of 0 cm and 20 cm ground temperature in Zhejiang was 0.2 ℃·（10 a）-1 (P＜0.05) from 1905 to 2018. The highest, lowest and average value was 20.5,16.5 and 18.6 ℃ at a depth of  0 cm, and 19.9, 16.1 and 18.1 ℃ at a depth of 20 cm, respectively. (2) Under the background of climate warming, the ground temperature in Zhejiang Province experienced a “coldwarm” climate evolution, and the ground temperature was lower before the mid1990s and higher after that. Two obvious rising stages were during 1905-1925 and 1991-2018, respectively. (3) The spatial distribution of 0 cm and 20 cm annual average ground temperature in Zhejiang Province showed the same spatial distribution characteristics with low in the north and high in the south. The high value areas were distributed in Wencheng, Longquan, Lishui and the south of Wenling, while the low value areas were distributed in Anji, Xiaoshan, Deqing, Huzhou, Changxing. (4) Obvious oscillation periods of 2-6 years, 6-8 years and 16-20 years in different periods were detected through analyzing annual average ground temperature of 0 cm and 20 cm in Zhejiang Province from 1905 to 2018, and the abrupt point occurred around 1986.
