河北省建设用地扩张与经济增长的脱钩分析

利用2010—2015年河北省的相关数据，构建建设用地扩张与经济增长的脱钩模型，测算全省以及省域内138个县建设用地扩张与经济增长脱钩指数，借助探索性空间数据分析与GIS技术，研究脱钩指数空间集聚特征与空间分布格局规律，为进一步提升建设用地利用效率提供支撑。研究结果显示，2010—2015年全省建设用地扩张与经济增长的脱钩类型为扩张性复钩，脱钩指数为0.05～0.97；138个县建设用地扩张与经济增长的脱钩类型为扩张性复钩，脱钩指数为0.09～0.70。县域建设用地扩张与经济增长脱钩存在空间聚集规律，LISA 指数显示“高—高”关联(HH)主要分布在三河市、香河县、大厂回族自治县和邢台市东部4个县，“低—低”关联(LL)显著区，位于省域中南部地区的19个县。最后，在扩张性脱钩类型基础上将省域内138个县划分为3个级别。 

DECOUPLING ANALYSIS OF CONSTRUCTION LAND USE EXPANSION AND ECONOMIC GROWTH IN HEBEI PROVINCE

 This paper uses Hebei`s 2010—2015 related data to establish a decoupling model of construction land use expansion and economic growth, which is employed to estimate the decoupling index of the entire province and 138 counties within Hebei province by using ESDA and GIS, discusses its spatial concentrating features and distribution rules, providing references to improve construction land use efficiency. The decoupling index is 0.05-0.97 in the entire province from 2010—2015, implying an expansive decoupling, 0.09-0.70 in the 138 counties also implying an expansive decoupling. The spatial concentrating rule of decoupling between county construction land use expansion and economic growth shows that HH LISA index is mainly spreading in Sanhe, Xianghe and Dachang, and four counties in eastern Xingtai city, LL LISA in nineteen counties in central southern Hebei. The 138 counties are divided into three tiers based on the expansive decoupling types.
