摘要:

研究陕西省新型城镇化与生态环境耦合关系及情景预测,对陕西省新型城镇化与生态环境耦合协调具有重要的参考意义。以陕西省为研究区域,将社会面板数据与遥感数据结合,构建新型城镇化与生态环境评价指标体系,采用耦合协调度模型分析陕西省2010-2020年新型城镇化与生态环境耦合关系,运用空间自相关模型探究陕西省新型城镇化与生态环境耦合协调的空间分异规律,创新性地利用系统动力学模型探究陕西省新型城镇化与生态环境耦合协调水平的最佳发展路径。结果表明,1)陕西省耦合协调度在2010-2020年呈上升态势,经历了由濒临失调向中级耦合协调的发展过程;2020年,西安耦合协调度最高,为0.771,商洛耦合协调度最低,为0.571;新型城镇化滞后是制约新型城镇化与生态环境同步发展的重要原因。2)2010-2020年,全局Moran’s I指数由−0.204变为−0.369,p值为0.076,耦合协调度在全局自相关上存在较显著的空间负相关关系;局部空间自相关呈离散分布态势,其中HL型地区以西安、铜川为代表,LH型地区以商洛、渭南、汉中为代表。3)协同发展型是陕西省最优的发展方案。当常住人口增长率控制在0.006,GDP增长率控制在0.055,建成区增长率控制在0.062,一般财政支出控制在0.320,用水率减少率控制在−0.025,维持现有耕地规模,环保支出系数提升至0.043时,在此情景下到2025年耦合协调度将为0.883。

Abstract:

New urbanization and the ecological environment are two systems that affect each other. If not coordinated, they can cause a series of ecological and environmental problems. Research on the coupling relationship between new urbanization and the eco-environment in Shaanxi Province and scenario prediction has important reference significance for the coupling coordination between these factors. Using Shaanxi Province as the study area, social panel data and remote sensing data were combined to establish an evaluation index system for new urbanization and the ecological environment. The coupling coordination degree model was used to analyze the coupling relationship between new urbanization and the ecological environment in Shaanxi Province from 2010 to 2020, and the spatial autocorrelation model was used to explore the spatial differentiation law of the coupling coordination between these factors. This study innovatively uses a system dynamics model to explore the optimal development path of the coupling coordination level between new urbanization and the ecological environment in Shaanxi Province. The results showed that 1) the coupling coordination degree of Shaanxi Province is on the rise from 2010 to 2020, and it has experienced a development process from near imbalance to intermediate coupling coordination. In 2020, Xi’an had the highest coupling coordination degree (0.771), and Shangluo had the lowest coupling coordination degree (0.571). The lag in new urbanization is an important factor restricting the synchronous development of new urbanization and the ecological environment. 2) From 2010 to 2020, the global Moran’s I index changed from −0.204 to 0.369, and the coupling coordination degree had a significant negative spatial correlation with global autocorrelation. Local spatial autocorrelation showed a discrete distribution trend, in which the HL-type region was represented by Xi’an and Tongchuan, and the LH-type region was represented by Shangluo, Weinan, and Hanzhong. 3) Collaborative development is the best development plan for the Shaanxi Province. When the growth rate of permanent resident population is controlled at 0.006, the GDP growth rate is controlled at 0.055, the growth rate of built-up area is controlled at 0.062, the general fiscal expenditure is controlled at 0.320, the reduction rate of water consumption is controlled at −0.025, the current cultivated land scale is maintained, and the environmental protection expenditure coefficient is increased to 0.043, In this scenario, the coupling coordination degree will be 0.883 by 2025. The research results provide a reference for the coordination between new urbanization and the ecological environment in Shaanxi Province and other cities.
