Research on Coupling Coordination Evaluation of Sustainable Land Use and Economic Development: A Case Study of Guangdong Province, China

초록

Sustainable land use is an essential part of the regional natural ecosystem. Likewise, economic development is needed for national prosperity, societal progress, and the high living standards of people. However, some regions blindly pursue economic development and ignore sustainable land use, reducing the level of sustainable land use and hindering economic development. Hence, exploring the coupling coordination between sustainable land use and economic development is conducive to the overall economic development and land protection in any region. Hence, this study collected data on the land use and economic development in Guangdong Province, China for 2008 and 2019 and established the evaluation index system of sustainable land use and economic development for the province. Further, a coupling coordination model of sustainable land use and economic development was established to measure and analyze the level of coupling and coordination between sustainable land use and the land use subsystems, and economic development in the province, respectively. The results of the measurement and analysis were as follows. The sustainable land use and regional economic evaluation values of the province changed during 2018 - 2019. In addition, the respective coupling coordination levels of the two sustainable land use subsystems maintained an upward trend during the period. Meantime, the contribution of the overall development of the two subsystems to their respective coupling coordination degree had been increasing during the period. In particular, this coupling coordination degree had changed from a low to a good coupling coordination stage. Hence, the construction of environmental facilities should further be improved to realize the ecologically, economically, and socially sustainable development of land resources in the province. In particular, the province should promote the optimization of industrial structure and develop tertiary and high-tech industries to coordinate sustainable land use and economic development in the province.
