Abstract:

Land-sea coordination is an important strategy for constructing a powerful marine country. It is of great significance to evaluate the coordinated development level of the coastal zone—the core area of land-sea coordination—to promote the sustainable development of such areas. Taking the coastal zone complex system of Wenzhou City as the research area and using data during 2010-2018, this study selected relevant evaluation indicators of the land and marine subsystems to build a comprehensive evaluation model of coastal zone complex system development level, and used the coupling coordination degree model, information entropy, and degree of sequence to evaluate the composite system coordinated development in the study area and explored the mechanism of influence of coastal zone exploitation on its coordinated development level. The results show that: 1) The overall development level of the land and marine subsystems showed an upward trend. The high value areas of the comprehensive development index of the land subsystem were concentrated in the main urban area of Wenzhou, while the low value areas were concentrated in the central and southern parts of the city, and the development gap between the districts and counties increased. The internal coordination of the land and marine subsystems has gradually increased and reached a good coordination state. The coupling degree of the coastal zone composite system is close to or up to 1, which indicates a benign resonance coupling state, and the coupling coordination degree also keeps improving and reaches a good coordination state. 2) In the study period, the information entropy of the coastal zone complex system gradually decreased, and the degree of sequence kept rising, with a positive trend of coordinated development. 3) The mechanism of influence of coastal zone development on the coordinated development level of coastal zone complex system is mainly manifested in four aspects: improving the transportation and utilization capacity of land and marine energy resources, changing land and marine ecological environment, promoting land and sea industrial agglomeration and strengthening subsystem association, and promoting land and sea social and cultural development.
