洞庭湖生态经济区乡村人—地—业耦合协调度时空分异

Rural Population-Land-Industry in Dongting Lake Eco-economic Zone:Spatial-temporal Differentiation of the Coupling Coordination Degree

乡村是由人口、土地、产业等核心要素有机组合而形成的复杂巨系统。为了探究乡村人—地—业之间的互动关系,本研究基于洞庭湖生态经济区县域面板数据,选取“人口—土地—产业”乡村发展三要素,通过构建耦合协调度评价指标体系,运用耦合协调度模型深度刻画洞庭湖生态经济区乡村人—地—业耦合协调发展的空间分异特征。结果表明,洞庭湖生态经济区乡村人口、土地、产业各子系统发展水平总体呈现差异较大、不均衡的特点;大部分县域乡村人—地—业发展处于协调耦合阶段,形成以洞庭湖生态经济区东部岳阳市发达区域为核心并以圈层的形式逐渐向外扩散的空间格局,呈整体水平逐年上升的趋势;耦合协调度呈现勉强协调、初级协调、中级协调和良好协调4个类型,乡村人—地—业耦合协调度在整体上呈现出由初级协调向中度协调发展的逐年上升特征。

The rural area is a complex and giant system formed by the organic combination of core elements such as population, land and industry. In order to explore the interaction between rural population, land and industry, this paper used these three elements of rural development to construct the evaluation index system of the coupling coordination degree based on the county panel data of the Dongting Lake Eco-economic Zone.Then, the paper adopted the coupling coordination degree model to deeply portray the spatial-temporal differentiation of the coupling coordination of rural population-land-industry in Dongting Lake Eco-economic Zone. Results showed that the development of the subsystems with rural population, land and industry in the Dongting Lake Eco-economic Zone was generally very different and unbalanced;the development of rural population-land-industry in most counties was in the stage of coupling coordination, forming a spatial pattern centered on the developed area of Yueyang City in the east of Dongting Lake Eco-economic Zone and gradually spreading outward in the form of circles, which showed an overall upward trend year by year. The coupling coordination degree had four types: bare coordination, primary coordination, intermediate coordination and good coordination. The rural population-land-industry coupling coordination degree as a whole showed the characteristics of increasing from primary coordination to intermediate coordination in the study area.
