摘要
城市用地规模扩大是城市化的重要标志之一。县域城市具有衔接大城市与广大农村的重要功能,研究其用地规模空间分异规律对于理解城市地理过程具有重要的意义。该研究在Arc GIS10.0平台支持下,提取湖北省2010年各县市县城面积及县域总面积数据,结合各县市的社会经济等信息,利用GIS手动分级法对全湖北省各县域城市的空间分异特征和规律进行研究。结果表明:湖北省各县域城市土地城市化空间分异和经济发展水平的空间分异相协调,即区域内土地城市化发展存在很大的不平衡性,以武汉市为中心,在长江沿岸平原区和重要铁路沿线县城面积与县域面积占比都较大,在经济边缘地带的鄂西和边远山区县城面积与县域面积占比都很小,而鄂中大部分县市占比比较大,鄂北和鄂南地区县市占比处于居中位置。
Urban land scale is one of the important symbol of urbanization. County city has a significant function of big cities and vast rural cohesion. Research the spatial and differential laws of the land use scale is of great importance to understanding urban geography process. With arcgis10. 0 platform support,the extraction of 2010 counties of Hubei Province city area of the county and the county a total area of the data,combined with various information such as the social economy,using GIS manual classification method on the spatial differentiation characteristics and regularity of each county city in Hubei Province were studied. Research shows that： the county,Hubei Province urbanization space differentiation of urban land and the coordinated economic development level of spatial differentiation. The area of land urbanization development there is a big imbalance,taking Wuhan as the center,in the plains and important town along the railway area along the river and the county area are larger than,on the edge of the economic zone of western HUBEI and remote mountain town area and the county area proportion are small,but EZHONG accounts for most of the counties and cities than is bigger,north Ordos and area counties and cities of the center position,the research reveals the counties of Hubei Province,the spatial differentiation characteristics of urbanization.
