- Abstract:
-
The expansion of Kuitun city was analyzed by using Landsat TM, ETM+ and ALOS/AVNIR-2 remote sensing images, and urban land use information was accesed and the urban expansion speed, expansion intensity index, fractal dimension and elastic coefficient was calculated. The results showed that urban expansion was more obvious. Urban land scale was expanding, and the increased urban area mainly originated from the grassland and unused land. The expansion intensity in the period of 1989—2000, 2000—2010 was 9.69% and 9.72%, respectively. The urban spatial pattern was changing from epithelial type to packing type. Elastic coefficient was less than 1.12, the population growth rate was higher than urban growth rate. The compact index was decreasing while the urban fractal index was increasing. It implied that the urban special configuration became more and more irregular and complex. According to the analysis result, the development of border areas was put forward, and coordination of the urban size with the population growth rate was proposed.
