【摘要】：论文基于耕地保护、建设用地集约利用和城镇化的交互耦合机制,以陕西省为例,通过构建耦合协调模型,分别从时空两个维度对其耕地保护、建设用地集约利用和城镇化的耦合协调关系进行研究。结果表明:1)从时间序列上看,2005—2014年陕西省耕地保护、建设用地集约利用和城镇化整体耦合协调度呈上升趋势,由中度耦合协调发展为高度耦合协调(0.549~0.800)。耦合度方面,以2009年为界,耕地保护、建设用地集约利用和城镇化两两及整体耦合度呈先升后降的倒"U"型;协调指数方面,以2007和2009年为拐点分为3个变化阶段,其中耕地保护和城镇化协调指数T2、建设用地集约利用和城镇化协调指数T3以及三系统总协调指数T总体呈上升趋势,而耕地保护和建设用地集约利用协调指数T1下降幅度大于上升幅度。2)从空间序列上看,2014年陕西省耕地保护、建设用地集约利用和城镇化耦合协调呈现"西北高、东南低"的特征。
[Abstract]:Based on the interactive coupling mechanism of cultivated land protection, intensive use of construction land and urbanization, this paper takes Shaanxi Province as an example, and constructs a coupling coordination model to protect cultivated land from two dimensions of time and space. The coupling and coordination relationship between intensive utilization of construction land and urbanization was studied. The result shows that the cultivated land protection in Shaanxi Province from 2005 to 2014 is viewed from time series. The overall coupling and coordination degree of intensive utilization of construction land and urbanization is on the rise, from moderate coupling and coordination to highly coupled coordination 0.549 0.800. In terms of coupling degree, the boundary is 2009. Cultivated land protection, intensive use of construction land and urbanization and the overall coupling degree of the first rise and then decline of the inverted "U" type; In terms of coordination index, the inflection point of 2007 and 2009 is divided into three stages, among which the coordinated index T2 of cultivated land protection and urbanization. The coordination index T _ 3 of intensive utilization and urbanization of construction land and the total coordination index T of the three systems are on the rise as a whole. In 2014, cultivated land protection in Shaanxi Province was protected in 2014. The decrease of T1 was larger than that of increase. 2) in spatial sequence, the cultivated land protection in Shaanxi Province in 2014. The coupling of intensive utilization and urbanization of construction land presents the characteristics of "northwest high and southeast low".

【正文快照】： 作为中国共产党第十八次全国代表大会的重要议题,新型城镇化和土地问题引起了广泛关注。理想的城镇化进程应该与土地利用协调发展,与耕地保护和建设用地集约利用之间形成一种动态的要素交换关系。然而,由于我国城镇化建设过快和土地制度改革滞后[1],城市扩张以外延式发展为主,
