新型城镇化背景下的土地利用空间差异研究——以甘肃省为例

Spatial Difference of Land Use under the Background of New Urbanization——A Case Study of Gansu Province

文章以甘肃省12个地级市、2个自治州为研究对象,从投入产出水平、区域关系的合理性、人地关系的融洽性、空间载荷程度四个方面来构建评价体系,用以评析城镇建设用地的节约集约利用水平。结果表明:甘肃省整体呈现出生态效益(1.9758)>经济效益(1.9109)>社会效益(1.7135)的基本特征,三者效益之间差异不大,城镇建设用地利用水平粗放、低效,多数地区仍处于轻度失调和濒临失调阶段;从空间相关性分析,甘肃省城镇建设用地耦合协调度在空间上随机分布,呈相互独立的状态,在空间上没有强极化效应,甘肃省区域发展不平衡,空间差异明显,中部最高,西部最低。

This paper takes12prefecture-level cities and2autonomous prefectures in Gansu Province as the research object,andconstructs the evaluation system from four aspects:input-output level,rationality of regional relations,harmony of human-landrelationship and spatial load,to assess the intensive level of urban construction land use.The results show that the ecological benefitlevel(1.9758)is higher than the economic benefit level(1.9109),while the social benefit level(1.7135)of Gansu urban constructionland intensive use is the lowest.The differences among three types of benefits are not significant.As a whole,the urban constructionland use in Gansu is extensive and inefficient,and most areas are still in mild imbalance or on the verge of imbalance.From spatialcorrelation analysis,the spatial distribution of urban construction land in Gansu is random,which is independent of each other,andthere is no strong polarization effect in space.The regional development of Gansu is not balanced,and the spatial difference is obvious.The central region is highest,while the west region is the lowest.
