空间信息技术支持下的福州市城市用地扩张时空特征研究
|
摘要
城市化是社会发展和经济增长重要动力,遥感和地理信息系统技术(GIS)已成为监测、分析城市发展的重要手段.该文选择我国海西地区重要门户福州市为研究区,以2000年~2015年多期Landsat TM/ETM+影像为数据源,对福州市城市用地空间分布信息进行提取,分析了2000~年~2015年福州市城市用地扩张的时空特征;同时结合福州市2000年~2015年社会经济数据和人文数据,探讨了城市扩张的主要驱动因素.结果表明:在时间上,福州市城市用地扩张总体呈上升增长趋势,尤其是2010年以来城市用地扩张快速发展;在空间上,福州市城市用地扩张呈现向西偏北方向移动;在驱动力上,人口、经济的发展以及高程、坡度、灯光、到一般公路、学校、医院的距离是影响福州市城市用地扩张的重要因素.
Urbanization is an important driving force for social development and economic growth.Remote Sensing(RS)and geographic information system(GIS)technology have become important means of monitoring and analysis of urban development.In this paper Fuzhou City,which is an important gateway in the west of china,is chosen as the research area,and the Landsat TM/ETM+images of Fuzhou City in 2000~2015are taken as the data source.The spatial information of Fuzhou urban is extracted,and spatial characteristics of land expansion along with its driving factors are analyzed from2000 to 2015in Fuzhou city.At the same time,the driving factors of city are studied in combination of the social,economic and cultural data of Fuzhou city from 2000 to 2015.Results show that in time,Fuzhou urban land expansion exhibits an overall upward trend,especially since 2010,when urban land expansion develops rapidly.In space,Fuzhou city urban land expansion was moved westward in the space.For the driving force,the development of population and economy along with DEM,slop,light,road,school and hospital are important factors to affect the expansion of urban land of Fuzhou city.
