The paper use the GIS methods to creating the basic spatial information database, and processing the polygon data by overlapping analyst, the linear data by network analysis, the statistic data by join analysis, the evaluate data by superaddition analysis, and these methods make the data collection, organization and analyst more easier, and the thematic map make the result more intuitionistic.
