Abstract: With the promotion of the establishment of Marine national parks in China, the coordinated development of communities has become a key content. However, for a long time, the management of Marine protected natural areas in China is relatively extensive, and the national park community coordination concept emphasizes community co-management, but the community utilization is relatively excluded in practice. The coordinated development mechanism of Marine national parks in China needs to be further constructed. This article selects four cases of marine national parks in developed countries: Australia′s Great Barrier Reef National Park, Biscayne National Park in the United States, Pembrokeshire Coast National Park in the United Kingdom, and Japan′s Shiretoko National Park. It summarizes the characteristics of community-coordinated development in marine national parks from three aspects: community coordinated development goals, sustainable marine utilization management, and marine conservation and co-management. On this basis, the framework for reference for the coordinated development of Marine national parks in China is constructed, and suggestions on the coordinated development goals, paths and specific measures of communities are put forward.
