基于GIS的武汉市滨湖土地利用演化研究

GIS-based Research into Evolution of Wuhan City's Lakeside Land Use

武汉市因多湖多水而闻名,城中湖数量居全国首位。武汉市滨湖区作为湖陆链接的重要生态区域,不仅承载整座城市的历史文化脉络,同时也是城市重要的经济增长区域。在人地矛盾日益突出的大背景下,多年来,由于人多地少的原因导致武汉市滨湖土地利用性质发生着巨大改变。运用GIS数据提取方法,针对武汉市不同历史年份滨湖区湖泊边界的用地性质演化情况进行分析,得出武汉市滨湖土地利用的演化特征与内在驱动机制。为改善武汉市滨湖土地利用与开发结构调整提供数据基础,为探索武汉市高速城市化进程中滨湖土地利用的未来发展趋势提供第一手数据依据。

Wuhan has long been known for its abundant lakes and waters, and it has the most number of intra-city lakes in China. Wuhan＇s lakesides, which are important ecological areas for linking lakes and land, not only carry Wuhan＇s historical and cultural contexts but also Wuhan＇s key economic growth areas. Under the background of increasingly prominent conflicts between people and land, land shortage and increasing population in Wuhan cause huge changes in Wuhan＇s lakeside land use. This article uses GIS data extraction and analysis, analyzes the evolution of the land use along Wuhan＇s lake boundaries in different years, and seeks to identity the characteristics and inner drive mechanisms for evolution in Wuhan＇s lakeside land use. This article provides data base for improving land use and for adjusting development modes of Wuhan＇s lakeside areas, and presents first-hand data reference for exploring future trends in Wuhan＇s lakeside land use during Wuhan＇s high-speed urbanization.
