城市扩展及其驱动力遥感分析--以厦门市为例

以厦门市为例,利用遥感专题信息提取和空间叠加分析技术研究城市空间扩展,着重分析了厦门市从1989年到2000年11年间各区城市扩展的面积、速度和方向、城市扩展侵占周围用地的情况以及城市扩展的驱动力。分析表明,厦门市的城市空间扩展速度较快,2000年城市用地规模比1989年扩大了近2倍,城市用地扩展主要是侵占周围的耕地。厦门市经济的快速发展、外商投资的不断注入以及多山临海的地理环境决定着城市扩展的速度和方向,是城市空间扩展的主要驱动力。

URBAN EXPANSION AND ITS DRIVING FORCE ANALYSIS USING REMOTE SENSED DATA--A CASE OF XIAMEN CITY

The study on the urban expansion and the driving forces of Xiamen city in SE China during the 11-year study period from 1989-2000 was carried out using the remote sensing thematic information extraction and spatial overlay technique. The area,rate and direction of the urban expansion during the study period in the respective region of Xiamen city were obtained. Moreover, the proportion of the land use occupied by the urban and the driving forces of the urban expansion were also analyzed. The result revealed that the speed of urban expansion in Xiamen city was quick and the urban area in 2000 was almost twice more than that in 1989. The arable land around the urban was main occupied land use type due to the urban expansion. The study also showed that the main driving forces causing urban expansion included the high-speed development of economic of Xiamen city, the foreign continual investment and the mountainous topographical environment.
