Land use and cover change (LUCC) is an important component of global environmental change research. Supporting by geographic information system (GIS), LUCC in Anhui province was explored through analyzing the land use data of mid1980s, mid1990s and 2000. The characteristics of LUCC in central and northern Anhui was comparatively centralized.During the period between 1987 and 2000, there was a decrease in paddy field, dry land, forestland and grassland, and an increase in rural settlements, urban settlements and water body. The changing extent between 1987 and 1995 was obviously smaller than that between 1995 and 2000. Then, Canonical Correlation Analysis is applied to identify the driving forces of LUCC in Anhui province. Through operations of the Statistical Package for Social Sciences (SPSS) and specific analysis of the results, the contribution of each driving force to land use change can be identified quantitatively. At the same time, tests are carried out through the canonical correlation coefficient and redundancy analysis. It is concluded that the LUCC in Anhui province is driven by the ratio of rural population to total population, number of village labors, local finance, resident's savings, occupying grain per capita and GDP per capita. To a great extent, agriculture structure change caused the decrease of farmland in Anhui province. Land use is a mirror of society, and its changes can reflect the socioeconomic developing course. The driving forces of land use changes should be paid more attention in order to draw relevant land use policies.
