Urban Land-use Pattern Dynamics of Metropolis Fringe Area: a Case Study of Nanjing City

Based on four-period TM remote sensing data and GIS spatial analysis methods,the paper describes urban land-use pattern dynamics of Nanjing city during recent 20 years.Urban land-use growth turnings occur in the year 1994,2000;growth spatial differences show growth hot poles and hot belts.Urban land-use growth temporal differences are the results of economical and social development process and dynamics evolution: regressive analysis finds that relativity coefficient between urban land-use growth ratio and urbanization,GDP,and Development Area is very high.Development Area is the primary source of urban land-use growth in 1992;Dong-shan New Urban District and University City become spatial growth core and new spatial form;Airport and highway networks give guidance for urban land-use spatial pattern.
