- [目的]探析人口、经济和资源环境三者之间协调及发展水平状况,阐明各县耦合协调关系及影响因素,为主体功能区规划实施提供有力支撑。[方法]基于2010年、2015年、2020年滇中城市群的自然、经济及人文数据,从主体功能区视角建立人口-经济-资源环境耦合协调发展评价指标体系。运用序关系分析法(G1)与熵权法(EW)确定综合权重,通过耦合协调度模型度量各县耦合协调关系,定量分析了2010年、2015年、2020年滇中城市群人口-经济-资源环境耦合协调演变状况,探析其发展规律。[结果](1)3个时段内,研究区人口在县域尺度呈空间正相关关系,且空间聚集性逐渐增强,呈现西部低人口密度聚集和中部高人口密度聚集态势且常年稳定;(2)2010—2020年,人口、经济和资源环境三者之间的耦合协调度综合发展水平有微弱提升,严重失调的协调类型逐渐消除,濒临失调占比46.94%成为最主要的协调类型;(3)人口、经济和资源环境两两耦合协调分布不均,其中2020年人口-经济综合耦合协调指数最低为0.454 3,协调度水平时空分布与三系统协调评价结果吻合度是两两耦合协调评价中最高的,对人口-经济-资源环境耦合协调评价结果影响最大;(4)在主体功能区划实施前后,国家重点开发区两两耦合协调水平变化显著,人口-经济-资源环境整体耦合协调水平较低且有倒退趋势,省级重点开发区长期稳定可控;(5)研究区的人口、经济和资源环境三者之间存在较强的相互作用关系,但协调性在一定程度上处于制约状况。[结论]高耦合协调性主要依赖于人口对市县区经济的带动作用。重点开发区的有效实施必须抓好人口与经济协同发展,人口和经济协调是未来优化主体功能区的重点方向。
- Abstract:
- [Objective] The purpose is to explore the coordination and development level among population, economy, and resources environment, clarify the coupling coordination relationship and influencing factors among counties, and provide strong support for the implementation of the main functional zone planning. [Methods] Based on the natural, economic, and cultural data of the central Yunnan urban agglomeration in 2010, 2015, and 2020, an evaluation index system for population-economy-resource and environment coupling and coordinated development was established from the perspective of the main functional area. The comprehensive weights were determined using the order relationship analysis method(G1)and entropy weight method(EW), and the coupling and coordinated relationship of each county was measured through the coupling and coordinated scheduling model, quantitative analysis of the population economy resource environment coupling and coordinated evolution of the central Yunnan urban agglomeration in 2010, 2015, and 2020, and exploration of its development laws. [Results](1)In the three periods, the population of the study area showed a positive spatial correlation at the county scale, and the spatial aggregation gradually increased, showing a low population density concentration in the western region and a high population density concentration in the central region.(2)From 2010 to 2020, population-economy-resources and environment coupling coordination degree had been slightly improved, and the seriously unbalanced development of coordination was gradually eliminated, barely unbalanced development accounted for 46.94% and became the main type of coordination.(3)The degree of coupling coordination between the two systems unevenly distributed, and the lowest population-economy coupling coordination index was 0.454 3 in 2020, its spatial distribution of coordination degree was most similar to that of comprehensive evaluation, which had a great impact on three system comprehensive evaluation results.(4)Before and after the implementation of major function-oriented zoning, the coupling coordination level of national key development zones changed significantly, the overall coupling coordination level of population-economy-resource environment was low and had a retrograde trend, and provincial key development zones were stable and controllable for a long time.(5)The relationship between the three systems in the study area had strong interaction relationship, but coordination was restricted to a certain extent. [Conclusion] The high coupling coordination mainly relies on the driving effect of population on the economy of cities, counties, and districts. The effective implementation of key development zones must focus on the coordinated development of population and economy, and the coordination between population and economy is the key direction for optimizing the main functional areas in the future.
