摘要
基于聊城市1995～2015年两期遥感影像数据,利用监督分类方法对聊城市的绿地、人工建筑以及裸地面积进行统计,分析聊城市20年间的土地时空动态变化情况,进而分析聊城市20年间的城市扩张方向以及城市不同利用类型土地占地面积的时空变化趋势,结果表明,聊城市土地面积总量基本不变,绿地面积处于动态变化之中,不可利用土地面积减少,人工建筑面积增加.人口数量的增加及生产总值的提高一定程度上对聊城市的人工建筑占地面积的增加有影响.该文分析结果可对聊城市城市建筑群未来发展的方向的分析提供参考.
Based on the remote sensing image data of Liaocheng City from 1995 to 2015,using the supervised classification method,the green space,artificial buildings and bare land area of Liaocheng City,the spatial and temporal dynamics of land in Liaocheng City during the past 20 years,and Liaocheng 20 The direction of urban expansion during the year and the spatial and temporal trends of land use of different types of urban use are analyzed. The results show that the total land area of Liaocheng City is basically unchanged,the green area is in dynamic change,the land area that cannot be used is reduced,and the artificial building area is increased. The increase in the population and the increase in the GDP have affected the increase in the artificial floor space of Liaocheng. The results of this paper can provide a reference for the analysis of the future development of urban buildings in Liaocheng.
