Productive-Living-Ecological Function Evaluation and Coupling Coordination Degree Analysis in Ecological Corridor of Yangtze-Huaihe River
Journal Title: Bulletin of Soil and Water Conservation - Year 2023, Vol 43, Issue 2
Abstract
[Objective] The temporal and spatial characteristics and coupling coordination relationship of the productive-living-ecological function of land space for the ecological corridor of the Yangtze-Huaihe River were studied in order to provide a scientific reference for the future high-level development. [Methods] According to the factors affecting the productive-living-ecological function, an evaluation index system was constructed. The function was evaluated by the entropy method, and the coupling coordination degree model was used to analyze the coupling coordination. [Results] ① From 2010 to 2020, the score of the land space function in the ecological corridor of the Yangtze-Huaihe River increased rapidly from low level to high level. With the rapid growth of the production function, the living function exhibited a pattern of growth-decline-growth, and the ecological function exhibited a pattern of decline-recovery. The spatial distribution of the function was relatively balanced. ② The coupling index and the development index indicated rapid and sustained growth, and the coupling index growth rate was relatively fast. ③ The coupling coordination degree showed a rapid growth trend over time. It has developed from basic coordination and mild coordination to high coordination and higher coordination. Spatially, it has developed from a certain differentiation to a more balanced state. [Conclusion] From 2010 to 2020, the productive-living-ecological function of the Yangtze-Huaihe River ecological corridor increased rapidly, and the degree of coupling and coordination of the function evolved from mild coordination to high coordination. The cities in the area have developed from having large functional differences to exhibiting symbiotic integration and orderly development. The main factors affecting the function are the living function and ecological function indicators, indicating gradual improvement in the quality of life functions and the level of ecological functions. It will still be necessary to maintain a high-level development path so as to reach the stage of high coupling-advanced development-high coordination in the future.
