Abstract:

Coordinated promotion of ecological security and economic transformation is a necessary condition for coal-resource depleted cities to realize sustainable development. This paper takes 16 CRECs in China as an example, and constructs evaluation systems of ecological security and economic transformation through multivariate data. The evaluation values of two systems were calculated based on the entropy weight Topsis modeling. Using the coupled coordination model, the coordination for two systems was analyzed. The transfer probability matrix for coordinated states is explored based on Markov chains. Finally, through the use of Pearson correlation analysis, the primary factors influencing coupled coordination were determined. The results of the study show that: (1) The spatial and temporal variability in ecological security are more obvious, the overall city's economic transformation development is relatively smooth, the development trend of coordination is more strongly correlated with ecological security, and the raising of ecological security degree is a prerequisite for the enhancement of coordination; (2) the coordinated development is relatively stable, and the level of coupled coordination will ultimately converge to a state between high and medium coordination is unlikely to show a significant decline; (3) Pearson correlation analysis shows that the Natural population growth rate, Science and Technology Expenditures as a Percentage of Fiscal Expenditures, Investment in environmental infrastructure, Economic density, Road area per capita are the main factors influencing the development of coordinated.
