Among the main parts of the marine environmental protection and governance, marine environmental protection NGO plays an irreplaceable role, mainly in the areas of publicity and education, practice activities, policy participation, public opinion and so on. However, according to the survey data, the marine environmental protection NGO started late in China, and there are still many factors that restrict the development of them. Prominently reflected as the system supply shortage, lack of social support and weak self-organization ability, etc. In order to promote the formation of multi governance pattern in marine environmental protection, it is necessary to optimize its institutional environment, improve the public awareness of marine environmental protection, and broaden the organizational construction path of the marine ENGO themselves.
