解译了厦门市1986~2007年6个时间点的遥感影像,提取建设用地斑块,借助ArcGIS9.0空间分析模块和空间统计功能,进行缓冲区分析。通过绘制建设用地类型扩展量曲线图,分析波峰-波谷时空变化,结合同期自然和人文因素的变化,揭示建设用地扩展的驱动力。结果表明:① 自然因素和人文背景影响城镇用地扩展的基本格局;② 社会经济实力积累推动建设用地空间分布的演变;③ 城市化和工业化相互作用快速推动建设用地的扩展;④ 政策因素多层次地影响建设用地的时空变化。

After interpreted 6 periods of RS images from 1986 to 2007, this article extracted built-up land patches from them, got the area-weighed center for buffer analysis and generated curves of built-up land in Xiamen by the ArcGIS9.0 spatial analysis and spatial statistic model. Then, it analyzed the curves, which the peaks and troughs were changed by the spatiotemporal change. According to what had been done above, the driving forces of built-up land dynamics change were discussed, combined by the changes of physical and human factors in the same period. The results suggested that: firstly, physical and human backgrounds affected the basic spatial pattern of built-up land growth; secondly, the accumulation of socio-economy development impeled the evolution of built-up land growth distribution; thirdly, the interaction between urbanization and industrialization promoted the extension of built-up land rapidly. At last, administrative policies influenced built-up land spatio-temporal change on different spatial levels.
