In order to provide more explicit information to guide future land use planning and related policies making of Jiangsu Province, the change characteristics of land use and the mean species abundance (MSA) index of Jiangsu Province were analyzed with the period of 1990 to 2008. Land use data of Jiangsu Province were derived from interpreting remote sensing images. Five time nodes were selected, namely, 1990,1995,2000, 2005 and 2008. GIS analysis and mathematical statistics ways were used. The results showed that the land use of Jiangsu Province had changed a lot during the period of 1990 to 2008; great changes had taken place on different land use types. Generally speaking, comprehensive land dynamic degree index and land use degree comprehensive index presented rising tendency with time going; cultivated land was the source of land use loss, while construction land was the sink of land use loss; the centroids of different land use types showed different shift style, among of them, the centroids of construction land shifted southeast evidently; There was significant unbalance of land use change between different area and temporal; from the aspect of time, the quantity and intensity of land use change after 2000 were higher than those before 2000 apparently; from the aspect of spatial scale, the transformation frequency of land use in southern Jiangsu Province was higher than that in northern Jiangsu Province; in the study period, the distribution of different land use types didn’t show difference significantly among 13 prefecture level cities; the MSA index which reflected the change of biodiversity decreased continuously.
