Spatial-Temporal Variance of Coupling Relationship between Population Modernization and Eco-Environment in Beijing-Tianjin-Hebei

Abstract

Steady population growth promotes economic and societal progress, and the symbiotic coordination between the ecological environment and the local population is the necessary requirement for realizing sustainability. We used population modernization and ecological environment data of the Beijing-Tianjin-Hebei from 2005 to 2016 to construct two index systems. We used the variation coefficient method, the coupling degree model, and a geographical detector to analyze the coordination degree of population modernization and the ecological environment. The results showed that: (1) From 2005 to 2016, the coupling degree was stable at a high level, the degree of coordination increased, and the growth rate decreased; (2) From the perspective of spatial distribution, the types of good harmony and high harmony were located in the middle, eastern, and western regions. The adjacent disorder and moderate disorder regions were distributed in the north and south sides; (3) Through influence detection, we found the main factors that influenced the spatial distribution of coordination degree were the natural population growth rate, health technicians/10,000 people, etc. These factors had some characteristics of space-time heterogeneity. Such results can contribute to the understanding of characteristics of population-environment development in different regions, promoting sustainable development of regional environment in Beijing-Tianjin-Hebei.

Quantitative Analysis of the Coupling Coordination Degree Between Urbanization and Eco-environment in Mongolia

“…Index system for urbanization and the eco-environment assessment The relevant research results are thoroughly taken into account when establish the index system to better assess the coupling coordination degree between urbanization and the eco-environment in Mongolia (Ding et al, 2015;Li et al, 2019;Yao et al, 2019). Urbanization is a comprehensive development process of various aspects.…”

The Coordinated Relationship between Investment Potential and Economic Development and Its Driving Mechanism: A Case Study of the African Region

“…where M i is the evaluation index; w i is the weight. For more details on the operational steps, refer to Li et al and Li et al [18,19]. The CCDM evaluates the degree of correlation between two or more systems and is often used in research on urbanization, ecologicalization, population growth, and innovation capacity building.…”

Dynamic Analysis of the Coupling Coordination Relationship between Urbanization and Water Resource Security and Its Obstacle Factor

“…A way to distinguish the importance of these indicators in each system is to assign them different weights. The variation coefficient method is based on the information contained in the index data to evaluate the importance of difference indexes, which is a method of objectively calculating weights [39,40]. The variation coefficient method believes that when the variation degree of the indicator is greater, the ability of the indicator to distinguish different evaluated objects should then be stronger, and the weight should be larger [41].…”
