Research on the Interactive Coupling Relationship between Land Space Development and Eco-Environment from the Perspective of Symbiosis: A Practical Analysis of Henan, China

As a key issue in China's sustainable development, land space development (LSD) creates increasing pressure on the environment. Thus, a better understanding of the relationship between LSD and the eco-environment is necessary for Chinese policymakers to realize sustainable high-quality development. LSD and the eco-environment are closely related and mutually dependent, and the coupling coordination pattern between LSD and the eco-environment has great significance to promoting high-quality development and ecological civilization construction in the region. This study highlights the equilibrium between LSD and ecological protection and introduces symbiosis theory to measure the degree of coordinated and symbiotic development in the Henan province, using data from 2000-2018. The coupling coordination degree model was used to evaluate the coupling coordination relationship of spatial-temporal patterns and development type characteristics. The evaluated results show that there are regional gradient differences in the level of LSD and the eco-environment, and the coupling coordination degree of LSD and the eco-environment in the Henan province are in the bare coordination stage and on the verge of imbalance at present. In addition, the spatial correlation pattern between LSD and the eco-environment was discussed. It is proposed that there is a positive correlation between the coupling coordination degree of LSD and the eco-environment. Moreover, this study suggested implementing a scientific and high-quality development path of land space, reasonably coordinating the social, economic, and eco-environment of the Henan province, then promoting regional sustainable development.
