Abstract:

Based on fourperiod TM remote sensing data and GIS spatial analysis methods, the paper described the pattern in urban landuse growth with the analysis of its mechanism in Qinhuai River Basin over last 20 years. Spatial and temporal differences were found in urban landuse growth: growth turning point occurred in the year 1994 and 2000 respectively; growth hot poles and hot belts were detected in the spatial difference; temporal differences were observed in urban landuse growth as a consequence of economical and social development; a relativity coefficient was found high between urban landuse growth ratio and urbanization, GDP, and Development Area. The above dynamics included the development area building, investment growth in 1992 and the administration replacement from county to district in 2000. Urban landuse growth pattern evoluted from economical and social development carriers' changes, and the Development Area was the primary source of urban landuse growth in 1992; Dongshan New Urban District and University City became spatial growth core and new spatial form; and airport and highway networks served as guidance for urban landuse spatial pattern.
