Identification and Optimization of Uncoordinated Coupling of Ecology-Urbanization-Tourism Based on Gray System Theory: A Case Study of Chongqing

Abstract

Abstract: [Objective] The development of each system of ecological environment, urbanization and tourism is crucial to the coordinated and sustainable socioeconomic development, and it is important to clarify the relationship and current situation among the three systems for the future development of Chongqing city. [Methods] Based on the gray system theory, the ecological environment, urbanization and tourism systems in Chongqing were studied from the perspective of non-coordinated coupling. The coordinated development of ecological environment, urbanization and tourism in Chongqing was explored by constructing gray correlation model and non-coordinated coupling model. [Results] ① The correlation degree of each indicator within the system of ecological environment, urbanization and tourism is above 0.5, with each indicator having a strong influence on the development of ecological environment, urbanization and tourism. The inter-system correlations are all above 0.65, which are at high or very high correlation levels, with the systems being closely linked and influence each other. ② The ecological environment, urbanization and tourism development levels all show an overall increase during 2000-2019, but the ecological environment is influenced by tourism and urbanization, showing large fluctuations. ③ The non-coordinated coupling degree of ecological environment, urbanization and tourism decreased from 0.7304 in 2000 to 0.0751 in 2019, and the non-coordinated coupling degree is gradually weakening, and the level of coordinated development among systems is getting better. [Conclusion] The relationship between the three systems of ecological environment, urbanization and tourism in Chongqing is close and the level of non-coordination is low. In the process of future urbanization and tourism development, more attention should be paid to ecological environment restoration to achieve coordinated and sustainable development among the systems.

Key words: grey system theory, tourism, urbanization, ecology, non-coordinated coupling
