The 9th International Conference on Energy, Resources, Environment and Sustainable Development (ERESD 2022)

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 eco-environment is closely related and mutually dependent, and the coupling coordination pattern between LSD and eco-environment has a great significance to promote 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 Henan, using data from 2000-2018. The coupling coordination degree model was used to evaluate the coupling coordination relationship of spatial-temporal pattern and development type characteristics. Evaluate results show that there are regional gradient differences in the level of LSD and eco-environment, and the coupling coordination degree of LSD and eco-environment in Henan province was in the bare coordination and verge of imbalance at present. In addition, the symbiosis mechanism between LSD and the eco-environment was discussed. It is proposed that the symmetrical mutualism symbiosis mode is the harmonious state for the development of land space. Moreover, this study was suggested to implement a scientific and high-quality development path of land space, reasonably coordinate the social, economic, and eco-environment of Henan province, then promote regional sustainable development.
