Quantitative Study on City Size Distribution in Jiangsu Province Based on Remote Sensing

MOU Feng-yun et al(College of River Sea,Chongqing Traffic University,Chongqing 400074)  
Based on the remote sensing images of 1979,1985,1995 and 2000,the built-up area of the 13 prefecture-level cities of Jiangsu Province were obtained.Based on these data,the urban primary indexes,fractal dimension and Gini coefficient were used to study the city size distribution and variation.The results indicated that rank-size law of 13 cities was approved based on urban land-use,which referred to city size,and the coefficient of determination(R2) were all more than 0.884.The primary city in Jiangsu Province developed very quickly,large-scale urban developed rapidly;city-size distribution was scattered,but there was weak central tendency.According to the analysis of fractal dimension D and the unbalanced index,we can draw the conclusion that the distribution of land size was uneven and the trend enhanced gradually,but the increasing speed reduced gradually.The rank-size distribution curve of Jiangsu built-up areas presented a parallel evolution manner.These results can provided a scientific basis for predicting the 13 cities built-up areas and urban land-scale systems in the future development of Jiangsu Province.
