基于遥感和GIS的东营市城市扩展分析

Analysis of the Urban Expansion of Dongying City Based on Remote Sensing and GIS

随着工业化的迅速发展,城市化进程加速,土地利用中的矛盾日趋紧张。本文以山东省东营市为例,利用1988年至2003年间的多时相卫星遥感影像等资料,利用GIS空间分析技术,对东营市近20年来城区扩展的时序特征和空间特征进行了深入的探讨。结果表明,东营市扩展很快,2003年的城市面积是1988年的4倍多。东营市的快速经济发展决定着城市扩展的空间方位和速度。

With the rapid development of industrialization, the process of urbanization is speeded up, which makes the contradiction in land - use more serious. This paper studied the case of Dongying City, the features of its expansion was analyzed. The multi - temporal satellite images from 1988 to 2003 were processed, tempo- ral and spatial features of Dongying City during the past 20 years were analyzed using spatial analysis techniques of GIS. The result revealed that the speed of urban expansion in Dongying city was very quick. The urban area in 2003 was more than 4 times of that in 1988. The result also showed that the main driving force of urban expansion is the high - speed economic development of Dongying city.
