基于RS/GIS的珠海市城市空间扩展
Urban Spatial Expansion of Zhuhai City Based on RS/GIS
摘要
Abstract
Taking Zhuhai as an example, this paper employs the ArcGIS technology to investigate the urban expansion of the city with TM remote sensing images from 1973 to 2008. The results show that:(1) In the early period (1973-1988), the expansion land of enclave type accounted for 84.51%of the new urban area, that of the edge type 12.76%, and that of the filling type 2.71%; (2) The period from 1988 to 1998 was the phase of spreading urban development, and the period from 1998 to 2008 was the phase of edge expansion of urban development. The enclave diffusion began in Jinwan and Doumen districts and spread substantially along the traffic lines. In the whole city, the enclave expansion was of the main urban spatial expansion type, and the edge type and filling type expansion had much lower proportion; (3) Since the establishment of the SEZ of Zhuhai, policy factors have brought great influence on the spatial expansion of the city; economic development and the growth of population are considered to be the direct driving force of the expansion.关键词
