[Coupling Coordination Between Ecological Environment and High-quality Development in Hebei Province]

Exploring the ecological environment and high-quality development of Hebei Province has great significance， and the degree of coupling and coordination among the two has guiding significance for promoting the integrated development of Beijing-Tianjin-Hebei and realizing the harmonious coexistence of humans and nature. Combining the advantages of "3S" technology and traditional technology， this study constructed an objective， systematic， and comprehensive ecological environment quality index system and a high-quality development index system from the perspective of new development concepts and realized evaluation of ecological environment quality and high-quality development by a comprehensive index method. Cold-hot spot analysis was used to analyze the spatial distribution pattern of ecological environment quality， and local spatial autocorrelation was used to analyze the spatial correlation characteristics of high-quality development. The coupling coordination degree model and geographic detector were used to measure the spatial correlation characteristics of the ecological environment quality and high-quality development quantitatively. The results of the study follow： ① There are obvious differences in the ecological environment quality of Hebei Province. The relatively low ecological environment quality area is the most widely distributed， accounting for 44.69% of the total area， mainly in the central， southern， and eastern plains. All levels of ecological environment quality show spatial aggregation characteristics. ② There are only three levels of high-quality development， namely， relatively high， medium， and relatively low. The relatively low level has the widest distribution， accounting for 53.04% of the total area， and is mainly distributed in parts of Chengde City， Zhangjiakou City， Xingtai City， and Cangzhou City. The main types of aggregation in the high-quality development area are high-high type and low-low type. ③ The interaction between ecological environment quality and high-quality development is significant， most of the regions are in the stage of coordinated development， and the interaction synergy between the two systems and the factors within the systems is significant. The ecological environment factor is the dominant factor for promoting the coordinated development of ecological environment quality and high-quality development. The research results provide decision-making reference for realizing the modernization of ecological civilization construction， high-quality development， and harmonious coexistence between humans and nature.
