基于GIS对南疆区域城市化综合水平的差异与城市组团发展研究

Study on Difference of Urbanization Comprehensive Level and Urban Agglomeration's Development in Southern Xinjiang Region Base on GIS

建立了南疆城市化综合水平指标体系,通过熵值法确定了各个指标的权重,并进行了排序。计算出2008年南疆地区42个县市的人口城市化水平、经济城市化水平、社会城市化水平和城市化综合水平,从地州和南疆角度进行了比较。把南疆地区城市化综合水平划分为四个等级,分析了不同等级所在县市的城市化发展的差异性,并用ArcGIS软件实现了空间上差异的图形化。根据陆大道提出的"点轴"理论原理,结合南疆地区城市发展的客观事实,提出以库尔勒市为中心的"库尔勒组团",以库车为中心的"库-拜组团",以阿克苏市为中心的"阿克苏组团",以喀什市为中心的"喀什组团",以和田市为中心的"和田组团"城市组团发展模式。

Index factor system of urbanization comprehensive level in southern Xinjiang was established, quotient of each appraise index factor was definited by entropy method, and order between each index was pursued. Population urbanization level.ecological urbanization level, social urbanization level and urbanization comprehensive level of 42 cities in southern Xinjiang in 2008 year was calculated , difference from prefecture and southern Xinjiang was studied. Urbanization comprehensive level in southern Xinjiang was divided four classes, difference of urbanization development of cities in different class was analyzed, and spatially difference graphical was achieved by ArcGIS software. On the basis of point--axis theory was putted forward by Lu da--dao, combining the objective fact of urban development, putting forward ＂Korla group＂center around Korla City, ＂ku--bai group＂ center around Kuqa County, ＂Aksu group＂ center around Aksu City,＂Kashgar group＂center around Kashgar City, ＂Hotan group＂ center around Hotan City urban group development model.
