Abstract:: The research of land use change can provide the references for the sustainable development and the ecocity development.In this paper,two Landsat TM images (respectively obtained in 1989 and 1997) and SPOT5 image (in 2004) were interpreted as basic information sources.With the support of remote sensing and GIS techniques,the classification system of land types of the region was established.Spatial information database of land use was created,and the basic data including properties and graph were analyzed.The spatial distribution and dynamic changes of land use over the past 16 years were studied,meanwhile the ecological effects of land use change are analyzed.The results show that the land use in Xiamen city has been obviously changed from 1989 to 2004,the cultivated land seriously decreased,while the settlement and construction land expanded all the time,and their patches have been congregating.At present the main land types are dominated by farmland and woodland,there is plenty of reserve land resources of wetland in Tong’an and Xiang’an district.The land use change has caused distinct ecological effects,such as habitat worsening,biodiversity decreasing,environmental quality and capacity declining etc.
