| 摘 要： | 赣榆县作为东部沿海城市城镇化发展尤为突出。本文选取1987年、2000年和2009年3期Landsat TM/ETM遥感影像作为主要数据源,利用ArcGIS软件数字化功能对城镇建成区进行提取,并将3期提取结果进行叠加分析,通过城镇扩展面积比重、城镇扩展指数、城镇用地扩展强度指数、城市紧凑度指数和城市用地分形维数模型对城镇扩展动态特征进行分析。

| Abstract: | Ganyu County as the development of urbanization in the eastern coastal city is particularly prominent.Three Landsat TM/ETM(1987,2000 and 2009)remote sensing images were selected as the primary data source,urban built-up areas were extracted by digital functions of using ArcGIS software,and overlay analysis was finished by 3 periods to extract the results,and the dynamic characteristics of urban expansion were analyzed by the area proportion of urban expansion,index of urban expansion,intensity index of urban expansion,index of urban compact and the fractal dimension model of urban land. |
