| 摘 要： | 我国已经进入快速城市化阶段,及时掌握城市空间动态扩展信息对于城市规划、城市建设、管理及决策具有重要的现实意义。本文以无锡市1991年和2001年Landsat TM遥感影像为数据源,提取建成区信息,并引入位序-规模分布理论进行城市扩展的模拟研究。结果表明无锡市东部、东南部和西部大幅度地向外扩展,建成区面积增加了52.4km2。位序规模分布模拟表明主城区城市用地斑块不断膨胀,平均斑块面积增大,大量碎小斑块被吸收和合并,模拟结果与建成区斑块的实际扩展变化比较吻合。

| Abstract: | China has already stepped into a rapid development period of urbanization process.Instantly obtaining the dynamic growing information of urban space is important to urban planning,urban construction,management and decission.Two Landsat TM remote sensing images of Wuxi city in 1991 and 2001 were used in this paper.The information of the buit-uparea was extracted from the classified images and Pareto-Zipf theory was introduced in order to study the simulation of urban expansion.The results showed that the rem... |
