Abstract: With the development of human activities to the ocean and extending to areas beyond national jurisdiction, conflicts will inevitably arise between various resource development and utilization activities and ecological environmental protection. In order to solve the social, economic, and ecological problems caused by the conflict, marine spatial planning in areas beyond national jurisdiction has become an inevitable choice, but the current marine spatial planning in areas beyond national jurisdiction has practical problems such as imperfect legal support system, planning subject restrictions and insufficient methodological data support. This article sorts out the origin and development of marine spatial planning, summarized the types and ideas of different practice forms of spatial planning in areas within and beyond national jurisdiction, such as marine protected areas, ecologically or biologically significant areas, reference zones, and areas of particular environmental interest, analyzed the management model(global model, regional model, hybrid model) and possible classification system(resource development zones, resource utilization zones, and resource protection zones) of marine spatial planning in areas beyond national jurisdiction in the future, and put forward the direction of the next work such as improving the legal foundation, establishing coordination mechanisms, and building a comprehensive evaluation system for existing problems in order to promote international ecological environment protection and sustainable use of resources.
