区域建设用地集约利用与城镇化的协调性评价

Coordination Evaluation of Regional Intensive Construction Land Use and Urbanization

城镇化是社会经济发展的必然产物,处于不同城镇化水平下的城市,其区域建设用地集约度也有所差异,两者耦合协调才能促进社会经济发展。以2001年、2005年和2009年为评价年期,基于河北省唐山市各地区1999—2009年社会经济和区域建设用地数据,引进耦合协调度"城镇化—区域建设用地集约利用"系统来有效度量不同城市的协调性,最后利用空间自相关表征这种耦合协调度的时空特征。研究表明:(1)研究区的耦合协调发展性稳步提高,多数地区的耦合协调度呈现先降低再升高的螺旋趋势,耦合协调类型从低度向高度协调类发展;(2)同步协调类随时间增加,呈现出从低度向高度同步协调发展,但是也存在一些不稳定和迟钝发展的地区;(3)耦合协调度的空间聚集效应越来越明显,表现为中心城区高高空间聚集,东南部沿海地区乐亭县和滦南县低低空间聚集。

Urbanization is the inevitable product of socio-economic development.Different levels of urbanization reflect different regional construction land intensive degrees.Only by coordinated development of them can socio-economic development to be promoted.Based on the socio-economic and regional construction land data from 1999 to 2009 in Tangshan,Hebei province,the year of 2001,2005 and 2009 is selected as the evaluation period.The coupling coordination degree is employed to measure the coordination of ＇urbanization-intensive regional construction land＇ system in different cities.At last,we used spatial autocorrelation analysis to reflect spatiotemporal characteristics of the coupling coordination degrees.The results indicate that：（1） coupling coordination improves steadily,most areas present spiral trend of coupling coordination degrees,and their types are from low to high class;（2） synchronous coordination classes are becoming more and more,indicating low to high synchronization.But there are some unstable and slow development regions;（3） coupling coordination degrees effect more obvious spatial aggregation.Central city shows high spatial aggregation,while the southeast coastal areas like Leting county and Luannan county show low special gathering.
