摘要
研究目的:探究关中城市群土地集约利用与碳排放关系,梳理二者演化特征。研究方法:脱钩分析,面板数据模型构建。研究结果:(1)2000—2014年关中城市群土地集约利用水平与碳排放水平均呈上升趋势,城市间差异明显;(2)关中城市群整体土地集约利用与碳排放尚未脱钩;(3)关中城市群土地利用集约度与碳排放强度曲线呈现倒N型。当土地利用集约度达到临界值后,碳排放强度将会逐步递减,并趋于平稳。研究结论:关中城市群土地集约利用与碳排放尚未脱钩且土地利用集约度未达到临界值,土地低碳集约利用还有待进一步优化。
The purpose of this paper is to study the relationship between intensive land-use and carbon emission, and then to figure out the evolution characteristics. Decoupling analysis and panel data model were used in this paper.The results show that： 1）during 2000 to 2004, the average levels of intensive land-use and carbon emission in Guanzhong urban agglomeration increased and the gaps among cities were significant; 2）the intensive land-use and carbon emission of Guanzhong urban agglomeration have not decoupled yet; 3）in Guanzhong urban agglomeration, an inverted N-type EKC curve of the relationship between the intensive land-use and carbon emissions emerged. When the landuse intensity reached the threshold, carbon emissions gradually diminished and then tend to moderate. In conclusion, the intensive land-use and carbon emission of Guanzhong urban agglomeration are neither decoupled nor reached the threshold. Hence, low carbon intensive land-use remains to be further optimized.
