| 为探讨城镇化与国土空间生态修复之间的耦合情况，以2007—2017年具有“老、少、边、山、穷”特点的广西、云南、贵州三个省份为研究对象，从“人、土、经、社”和“山、水、林、田、环”构建城镇化系统与国土空间生态修复系统评价指标体系，运用耦合协调模型、灰色关联模型探究区域城镇化与国土空间生态修复耦合协调时空分异特征及其驱动因素。结果表明，“老、少、边、山、穷”整体区域的国土空间生态修复水平2007—2015年高于城镇化水平，2015—2017年低于城镇化水平，且二者之间的差距呈扩大趋势。区内城镇化系统与国土空间生态修复系统的整体差异程度趋于扩大，且后者内部差异程度高于前者。城镇化系统与国土空间生态修复系统的耦合协调关系由轻度失调转变为初级耦合协调，区域整体耦合协调水平高于各省份，虽然耦合协调状况有所改善但仍然相对偏低，未形成良性互动机制。两系统各因素之间的关联度较高，且开展国土空间生态修复对促进城镇化发展的驱动力较高。研究表明，“老、少、边、山、穷”区域应统筹规划，基于边际分析理论，可将城镇化提高程度视为边际收益，将国土空间生态修复成本提升程度视为边际成本，以耦合协调度为约束，形成互为驱动的良性机制，实现二者的可持续发展。 |

| To better understand the coupling coordination mechanism between urbanization and territorial spatial ecological restoration, a typical study was conducted in three provinces with "revolutionary-minority-border-montanic-poverty" characteristics. This study constructed a coupling coordination system by which the relationship between urbanization and territorial spatial ecological restoration could be determined after which the coupling coordination and grey correlation models, were used to explore the spatiotemporal differentiation characteristics and driving factors of urbanization and ecological restoration. The results showed the level of territorial spatial ecological restoration throughout the "revolutionary-minority-border-montanic-poverty" region was higher than the level of urbanization before 2015 and was lower than that after 2015. The gap between these two categories was widening. The overall difference in the degree of urbanization and territorial spatial ecological restoration systems showed an increasing trend, and the degree of internal difference of the latter was higher than that of the former. The coupling coordination relationship between urbanization and territorial spatial ecological restoration systems had changed from slightly irregular to primary coordination, and the overall coupling coordination level of the regions was higher than that of the each provinces. Although the coupling coordination level had improved, it was still relatively low and did not result in the formation of a favorable mutual relationship. There was strong correlation among the indexes of the two systems; therefore, ensuring good territorial spatial ecological governance was a strong driving force for promoting the development of urbanization. The development of the "revolutionary-minority-border-montanic-poverty" region should be planned in a holistic manner. According to the theory of marginal analysis, the degree of improvement in urbanization should be regarded as a marginal benefit, the degree of improvement in territorial spatial ecological restoration should be regarded as a marginal cost, and the degree of coupling coordination should be taken as constraint with which to form a benign mechanism driven by the former two factors in order to ensure sustainable development. |
