摘要
通过对抚州市1998年、2008年和2018年的TM/ETM^+遥感影像的数据处理,动态监测了城市建成区的扩张。根据自组织的分形理论,用网格法研究了其空间发展的分形特征及演化,结果发现抚州城市具有分形性质,抚州市正步入一个快速发展的时期,同时城市形态分维正偏离城市理想状态。这些研究结果可为抚州市的总体和短期规划提供参考。
The extension of Fuzhou built-up area is monitored dynamically by the data processing of Landsat TM/ETM^+ images,which are obtained from 1998,2008 and 2018.Based on the fractal theory of self-organization,the situation that Fuzhou has the fractal feature and is stepping into a rapid growth period is worked out through the analysis of the urban fractal character and evolution by grid method.At the same time,the urban fractal dimension is straying from the urban ideal situation.According to those research results,it has a great benefit for Fuzhou city overall and short-term planning.
