摘要
文章应用GIS空间分析技术并采用综合指数法、变异系数法、重心转移分析等方法研究了淮海经济区土地集约利用水平的时空变化与分异,结果表明:(1)2000—2015年研究区20个城市土地集约利用水平均有不同程度的增长;(2)从时空分布来看,研究区土地集约利用水平分化程度呈现逐年增大的趋势,位于区域东部及北部江苏和山东下辖城市土地集约利用水平增长速度快于西部及南部城市;(3)2000—2015年研究区城市土地集约利用水平重心多数年份位于徐州,迁移方向向东向北;(4)2000—2011年研究区土地集约利用水平变异系数整体呈现出增大的趋势,2012—2015年变异系数差距虽未增加,但依然较大;(5)土地集约利用水平一定程度上反映了经济发展的水平,经济发展水平具有时间的滞后性。
This paper uses GIS spatial analysis technology and uses the methods of comprehensive index,coefficient of variation and gravity transfer to study the temporal and spatial variation and differentiation of land intensive use level in Huaihai economic zone.The results show that:(1)From 2000 to 2015,the level of land intensive use in 20 urban areas in the study area has increased to varying degrees;(2)From the perspective of time and space distribution,the degree of land intensive use level in the study area has increased year by year,located in the eastern and northern parts of the region,Jiangsu and Shandong cities.The level of land intensive use is growing faster than that of the western and southern cities;(3)From 2000 to 2015,the focus of urban land intensive use level in the study area is located in Xuzhou in most years,and the migration direction is east to north;(4)From 2000 to 2011,the overall coefficient of variation of intensive use showed an increasing trend in the study area.Although the coefficient of variation from 2012 to 2015 has not increased,it is still large;(5)The level of land intensive use reflects the level of economic development to a certain extent,and the level of economic development has the lag of time.
