By using Geo-information technology synthetically, this paper makes an in-depth analysis of the changing characteristic and driving force of land use in Fuzhou city. The main research contents include: to take TM data as information source to obtain two periods of land use state and this period of land use change information; to offer accurate space positioning information and fast localization of field investigation of the changing areas quickly with GPS; to use GIS to deal with data of many kinds of sources synthetically, including the integrated management, spatial statistics and synthetical analysis, use of the other data of the statistics and GIS management to carry on canonical correlation analysis, and to use variable of canonical correlation to explain the question of driving force of land use changes in Fuzhou city. Through spatial statistical analysis and canonical correlation analysis, we got to know that the area of land use change in Fuzhou city is distributed in all parts of the whole city, especially the eastern coastal area and around the basin of Fuzhou city .The variation tendency is that the paddy field and nonirrigated farmland show a decreasing tendency, but the forest land, water areas, construction land, garden plot and meadow show an increasing tendency. The change of land use is influenced both by the natural and socio-economic factors synthetically, the main influencing factors are the slope, average wind speed, per capita cultivated land, per capita grain sown area, rural workforce's density, income of township enterprise, grain per mu yield, net income of peasants, per capita agricultural gross output value, gross domestic product, per capita total volume of retail sales of social consumer goods etc.
