摘要
探索城市建设与低碳经济发展之间的互动规律对实现区域高质量可持续发展有着重要意义。基于此,本文以长株潭城市群为研究区,综合运用脱钩发展模型和灰色关联度等方法分析城市紧凑度和碳排放强度两者之间的互动关系及驱动因素。结果表明:(1)2005~2017年长株潭城市群UC指数以及各类功能紧凑度的耦合协调度总体呈上升趋势,但各市区仍存有较大提升空间;(2)研究期长株潭城市群CEI值呈逐年下降趋势,且各市区CEI值变化速率略有差异;总体来看大致可划分为高碳排放(2005~2007年)、持续减排(2008~2011年)和低碳优化(2011~2017年)3个阶段;(3)长株潭城市群UC和CEI多数年份处于强脱钩关系,少数年份表现为衰退脱钩及其他状态,各市区历年的脱钩状态和程度略有差异;(4)长株潭城市群UC和CEI的脱钩状态与各驱动因素的时空关联度表现不尽相同;整体来看,影响程度由弱到强依次表现为政府参与<科技创新<人口素质<城镇化水平<产业结构。未来城市建设过程中应注重各运行系统的耦合协调,在重视高品质城市开发的同时亦需结合自身资源禀赋创新打造城市的低碳发展模式。
Exploring the law of interaction between urban construction and low-carbon economic development is of great significance to achieving high-quality sustainable development in the region. Based on this, this paper takes the Changsha-Zhuzhou-Xiangtan urban agglomeration as the research area, comprehensively use the decoupling development model and gray correlation method to analyze the interactive relationship and driving factors between urban compactness and carbon emission intensity. The results show that:(1) From 2005 to 2017, the coupling compactness of the average compactness and various types of functional compactness of the Changsha-Zhuzhou-Xiangtan showed an overall upward trend, but the coupling coordination degree of each urban area still has a large room for improvement.(2) During the study period, the carbon emission intensity of Changsha-Zhuzhou-Xiangtan showed a year-on-year downward trend. The rate of change of carbon emission intensity varies slightly among the urban areas. In general, it can be roughly divided into three types: high carbon emissions stage(2005-2007), continuous emission reduction stage(2008-2011) and low-carbon optimization stage(2011-2017).(3) The average compactness and carbon emission intensity of the Changsha-Zhuzhou-Xiangtan urban agglomeration are in a strong decoupling relationship in most years. A few years are characterized by recession decoupling and other conditions. The decoupling status and degree of each urban area vary slightly over the years.(4) The temporal and spatial correlation characteristics of the decoupling state of UC and CEI in Changsha-Zhuzhou-Xiangtan urban agglomerations and the value of each drivers are different. On the whole, the degree of influence from weak to strong is government participation, technological innovation, population quality, urbanization level and industrial structure. We should pay more attention to the coupling and coordination of all operating systems in the process of urban construction in the future. And we should combine the re
