Taking Cangzhou City, a pilot city for heavy chemical industry in the Beijing-Tianjin-Hebei region, as the research object, time series data from 2010 to 2024 were selected. Based on the unique local resource endowment, a comprehensive evaluation system covering 15 indicators from four subsystems of carbon reduction, pollution control, green expansion, and economic growth was constructed. Entropy method, coupled coordination, and obstacle-degree model were used for quantitative calculation. The results showed that the comprehensive development level of Cangzhou City continued to improve during the research period, but the development pace of the four subsystems was unbalanced. The growth of green expansion relying on canal afforestation and saline-alkali tolerant wheat planting was the most prominent, and the carbon reduction link was the long-term core constraint for coordinated development. The coupling degree of the system continued to increase, but the coupling coordination was always below 0.5, and it was in a mild imbalance stage for a long time, showing the characteristics of "high coupling, low coordination". The progress of CCUS promotion, the scale of saline alkali land and canal greening, and the energy consumption per unit of GDP are the main limiting factors. Based on the shortcomings of local development, practical measures are proposed from three aspects: expanding carbon capture projects, improving the quality of characteristic ecological spaces, and perfecting diversified collaborative governance. This can provide empirical reference for similar heavy chemical industrial cities to coordinate ecological governance and industrial green transformation. |
