- [目的]探索“三生”空间适宜性之间的耦合协调关系,明确国土空间发展的主要矛盾和影响因素,为促进长株潭地区“三生”空间协调发展提供科学依据。[方法]基于长株潭地区发展现状,构建“三生”空间适宜性评价指标体系,分别评价生产、生活、生态空间的适宜性,并采用耦合协调度模型基于三类适宜性的空间分布分析耦合协调性,探索“三生”空间适宜性之间的作用关系。[结果]2000—2020年生产空间面积先减后增、生活空间面积加速递增、生态空间面积加速递减,大量农业生产空间和林地生态空间转化为工业生产空间和城市生活空间。“三生”空间适宜性呈现出由市区向外扩散的“生活—生产—生态”圈层空间格局特征,生产空间适宜性北高南低、中高外低,生活空间适宜性呈现“一片八核多点”分布特征,生态空间适宜性东高西低、南高北低。基于适宜性的“三生”空间格局中,生产、生活和生态空间分别占国土面积的34.36%,19.55%和46.09%,其与“三生”空间现状差异明显,突出生态保护的重点区域。研究区整体处于基本协调水平,高度协调、基本协调、临界失调和失调区域面积分别占国土面积的56.29%,36.65%,6.91%和0.16%。“三生”空间适宜性耦合协调度空间分异明显,反映出不同的国土空间发展矛盾,需采取针对性措施促进“三生”空间协调发展。[结论]“三生”空间适宜性之间呈现生态空间与生产或生活空间不协调、生产和生活空间较协调的特点,生态空间与生产空间之间、生态空间与生活空间之间适宜性的不协调是长株潭地区国土空间发展的主要矛盾,地形地貌是影响“三生”空间适宜性耦合协调度的根本因素。
- Abstract:
- [Objective]The aims of this study are to explore the coupling and coordinated relationship between the suitability of production-living-ecological space, to clarify the main contradictions and influencing factors of the development of territorial space, and to provide scientific basis for promoting the coordinated development of production-living-ecological space in Changsha-Zhuzhou-Xiangtan area. [Methods]Based on the development status of Changsha-Xiangtan area, the evaluation index system of spatial suitability of production-living-ecologyl space was constructed to evaluate the suitability of production, living and ecology space, respectively. The coupling coordination degree model was used to analyze the spatial distribution based on the three types of suitability to explore the relationship between the spatial suitability. [Results]The area of production space was first reduced and then increased, the area of living space increased rapidly, and the area of ecological space decreased rapidly. From 2000 to 2020, a large number of agricultural production space and forest land ecological space transformed into industrial production space and urban living space. The spatial suitability of production-living-ecology space presented the spatial pattern characteristics of of ‘life-production-ecology' circle layer, which spreaded from Changsha-Zhuzhou-Xiangtan urban area. The suitability of production space was high in north and low in south, high inside and low outside. The suitability of the living space presented the characteristics of ‘one piece, eight cores and multiple points'. The suitability of ecological space was high in east and low in west, high in south and low in north. In the production-living-ecology space pattern based on suitability, production, living and ecology space accounted for 34.36%, 19.55% and 46.09% of the land area, respectively. It was obviously different from the spatial situation of production-living-ecology space, highlighting the key areas of ecological protection. The research area was at a relative coordination level. High coordination, basic coordination, critical imbalance and imbalance areas accounted for 56.29%, 36.65%, 6.91% and 0.16% of the land area, respectively. The spatial differentiation of the spatial suitability of production-living-ecology space was obvious, reflecting the different development contradictions of territorial space development, so targeted measures should be taken to promote the coordinated development of production-living-ecological space. [Conclusion]The spatial suitability of production-living-ecology space presented the characteristics of the disharmony between ecological space and production or living space, and the relativecoordination between production and living space. The incompatibility between ecological space and production space and between ecological space and living space is the main contradictions in the development of territorial space in Changsha-Zhuzhou-Xiangtan area. Topography is the fundamental factor affecting the coupling and coordination of the spatial suitability of the production-living-ecological space.
