Abstract
The long-term strategy of Blue Economy aims to release the potential of marine resources through the sustainable development of the production system of marine products and renewable marine resources. As one of the most dynamic areas for the development of blue economy, the coastal zone is also a zone with strong interaction between land and sea. It is a complex nonlinear system with the most intensive space development and utilization, the most prominent pressure on resources and environment, and the most concentrated contradictions. This study uses the system dynamics method to establish the marine model and the coastal model, calculates and analyzes the sustainable development of the ocean and coastal zone system through the coupling of the land and the ocean model, focuses on the development of marine renewable energy, aquaculture, fisheries, marine pollution, marine engineering and other industries, as well as the development and utilization of marine resources, and studies the interaction between various factors. Better promote the development of marine blue economy through system coupling and coordinated development.
