The vertical correlation coefficients between two stations at intervals of 1-day are calculated with the 77 broad-band stations’microseisms records given by the Seismic Monitoring Network of Fujian，Guangdong，Jiangxi and Zhejiang Provinces from April 13，2010 to May 10， 2010. The authors got the different coefficients and added the interferential coefficients． Based on the chessboard test in seismology，the authors perform ambient noise tomography of Fujian Province (110°～123°E，21°～31°N) with the appropriate inversion matrix． The results imply that the signal-noise-ratio (SNR) increases proportional to the added times，and the group velocity of Rayleigh waves in Fujian Province is between 2.8km/s and 3.2km/s with average velocity 3.0km/s． The distribution of the group velocity is almost coincident with the topography and the geothermy of Fujian Province． But because of the effects of both the topography and the geothermy，the distribution of the group velocity in some areas is abnormal． From the group velocity distribution image，an obvious low velocity area can be found in the area of Zhangzhou basin and Fuzhou basin． It must be affected by both the sedimentary and the geothermy deposit in these two basins．
