This paper constructs a comprehensive evalua‐tion index system and uses the coupled coordination degree model to measure the coordinated development level of China’ s forest resources-economy-environment system. The results show that, across 2006‒2020, the level of coupled coordinated development of China’ s forest resources-economy-environment composite system fluctuates in an upward trend, thus gradually developing from an initial imbalance to a high degree of coordi‐nation;the level of coordinated development of each subsystem of the forest resources, economy, and environ‐ment also shows an upward trend. The factors influencing the coordinated development of the forest resource economy-environment system are, in order, the government’ s financial capacity, market environment, scien‐tific and technological innovation capacity, level of economic development, and strength of policy implemen‐tation. Therefore, this paper proposes some measures to improve the coordinated development.展开更多

Using the p...Collaborative governance between ecological environment and climate change is a novel signature in China's policy agenda. However, such coordination remains understudied, especially at the local level. Using the principal component analysis, entropy evaluation methods, and the Coupling Coordination Degree Model (CCDM), we evaluated the level of coordination between carbon and air quality mitigation from 34 low-carbon pilot cities in China. We also illustrated the mechanism and policy formation that leads to different coupling patterns at the local level using three case studies. We found that most pilot cities perform a medium level of coupling coordination between low carbon development and air quality. The result reveals that most low-carbon pilot cities score relatively well in low-carbon development. Further, there is a significant cleavage in air quality between cities in the North and those in the South, indicating pilot cities in the South coordinate better than those in the North. In particular, pilot programs in the Southwest and Southeast coastal region perform well in collaborative governance, while the Beijing−Tianjin−Hebei region is rated poorly because of the gap between air quality and low carbon development. Also, we found that the same low-carbon policy might have heterogeneous effects on different air pollutants and across different regions. The local government should adopt low-carbon development policies that address local level specific environmental and economic conditions to maximize their air pollution mitigation benefits.展开更多

This paper constructs a "Size-Density-Morphology" urban ecological resilience evaluation system, uses a coupling coordination degree model to measure the degree of coupling coordination between urbanization and ecological resilience in the Pearl River Delta from 2000 to 2015, and conducts an in-depth discussion on its spatiotemporal characteristics. The results show the following.(1) From 2000 to 2015, the urbanization level of cities in the study area generally increased while the level of ecological resilience declined. The coupling coordination degree between the two systems decreased from basic coordination to basic imbalance.(2) In terms of spatial distribution, the coupling coordination degree between urbanization and ecological resilience of cities presented a circular pattern that centered on the cities at the estuary of the Pearl River and increased toward the periphery.(3) Ecological resilience sub-systems played variable roles in the coupling coordination between urbanization and ecological resilience. Specifically, size resilience mainly played a reverse blocking role;the influence of morphology resilience was generally positive and continued to increase over time;the effect of density resilience was positive and continued to decline and further became negative after falling below zero. The main pathways for achieving coordinated and sustainable development of future urbanization and ecological resilience in the Pearl River Delta include: leading the coordinated development of regions with new urbanization, improving ecological resilience by strictly observing the three areas and three lines, adapting to ecological carrying capacity, and rationally arranging urban green spaces.展开更多
