Abstract
GIS Spatial Analysis is widely adopted in the research of land use change, especially in the spatial research of land use change. The data analyzed by GIS is mainly from original land use map and remote sensing. The model foundation includes spatio-temperal data model, attribute data model and principal model for acquiring land use characteristics. The data dealing process involves many functions of GIS, such as data conversion, edit function, spatial analysis, database operating, and statistic function. Taking Beijing area as an example, this paper illustrates GIS spatial analysis and its application in the research of land use change. There are some remarkable advantages using GIS in the land use change. It can integrate all land use information in one system, such as original land use maps, images, statistical data, and land attribute data. Furthermore, the spatial data can be analyzed in the system environment in order to produce information of regional land use change. At last, the spatial change, distribution can be printed with the mapping function of GIS. As the shortage of many analysis functions, the integration of GIS with user models is the main developing direction.
