摘要：In this paper, taking Jinan City as a case study, 2000 / 2005 ETM+ and Spot4 Pan images were interpreted artificially, and the spatial information of the two period land-use types was extracted. Based on this, the transfer matrix of the land-use types were calculated by the spatial statistical analysis method, which revealed the land-use change of Jinan City from 2000 to 2005. The landscape pattern indexes in 2000 and 2005 were calculated by using the landscape pattern analysis software Fragstats3.2, and the characteristics of the landscape pattern for land use and its evolution were analyzed. The results indicated: (1) During the 5 years, the LUCC of Jinan City showed that the arable land and the resident, industry and mining land increased significantly, the waters also increased, the grassland, the woodland and the unused land decreased, which reflected that the regional urbanization process was speeded up and the ecological environment was deteriorated. (2) The degree of the patch fragmentation increased, the number of patches increased from 7386 to 8129, resulted from the increase of rural resident land and reclaimed land. (3) The internal heterogeneity of the landscape reduced and the advantage of the farmland landscape increased significantly, which decreased the anti-jamming ability of landscape. During 2000 to 2005, Shannon diversity index (SHDI) decreased from 1.826 to1.785, which illustrated that the landscape heterogeneity reduced. (4) During the 5 years, the level of the ecological security reduced from 0.7588 to 0.6818 in Jinan city, which indicated that the ecological security state of Jinan was worse than before
