Regional difference of environmental evolvements is one of important aspects in world change research program. Changes in land cover and in the way people use the land have become recognized as important global environmental change in many areas. Land-use and cover changing (LUCC) is one of the major studies of global changing lately. Land-use is the term which covers the condition of used-land, the method, extent, structure, regional distributing and benefits in the land-use. It is affected by the natural condition or is enslaved to the conditions in society, economy and technology, and social production mode plays a decisive role in land-use; land-cover is the state of covering which is formed on account of the earth's surface or contrived by human being, is the summary of vegetation and artificially covering on the earth's surface. So land-use and cover changing is connecting closely. Land-use and cover changing information points that information on the position, distributing, range, and size of land-use and cover changing in the certain time. Motivated by a global concern for sustainability and environmental quality in city, a considerable number of studies have utilized satellite sensor data in the analysis of urban morphological change .some studies focused on the physical and socioeconomic drivers of change in urban land cover and implications on land use practices and resource management. Other studies went beyond the characterization of change and its causes and attempted to integrate remotely sensed data with models of urban growth to project future change. GIS and RS technologies are widely applied for LUCC studies providing a powerful tool for capturing, storing, checking manipulating, merging, analyzing and displaying data. Especially RS technology are also widely used for LUCC studies such as automatic discovery changing, automatic extraction changing area, confirmation changing type, using interactive explanation accessorily to extract the changing information of land-use in the research area. RS has an important contribution to make in the actual change in LUCC on regional. This paper studies land-use and land-cover change in Fuzhou area of Fujian Province, China. It builds a series of land-use change maps using Remote Sensing automatic monitoring and GIS spatial analysis techniques. Finally the paper briefly discusses the drive of land-use and cover changes. The study provides a reference to the sustainable development for the region.
