Abstract:The Kunming-Montreal Global Biodiversity Framework adopted by the United Nations Convention on Biological Diversity (CBD) at the Conference of Parties (COP15) has set a series of targets, including protecting at least 30% of the oceans by 2030 worldwide. In China, how to build a marine ecological civilization in synergy with the targets has become an important issue. This study analyzes the necessity of accelerating the construction of marine protected areas in China from the perspectives of adapting to international trends, fulfilling the responsibilities of international conventions, safeguarding maritime rights and interests, and implementing the maritime power and strategy. The feasibility is discussed from the aspects of national financial support, policy support and marine comprehensive strength support. It summarized and sorted out the problems in the construction of marine protected areas in China, including small scale, slow development and the large gap between domestic and international communities, the concept of marine management by land-based thinking, and the lack of land-sea classification, the imperfect management system, the backward technical standards and so on. With a problem-oriented approach, this study puts forward some countermeasures and suggestions to improve the management system of marine protected areas in China, optimize and integrate offshore protected areas, promote the construction of the South China Sea National Park, and focus on global marine protection and governance.
