Abstract: The purpose of establishing the national wetland park supervision system is to emphasize the effective supervision of the park's next development direction, construction content and management measures after the completion of the acceptance of the national wetland park, and highlight the continuity and standardization of the management of the wetland park. At present,China's post-event supervision in ecological environmental protection and nature reserve construction and management is still in the exploration stage, but has formed part of the experience through specific practice exploration. This paper analyzes the supervision and management system of domestic ecological protection such as central environmental protection inspectors,regional environmental protection inspectors, "green shield" special actions and the current regulatory means such as national parks, nature reserves, scenic spots, geoparks, forest parks, etc., and compares with the supervision methods of wetland parks in China. From strengthening planning guidance, innovating supervision technology, improving the institutional system,strengthening supervision and law enforcement, improving supporting norms, and strengthening effectiveness evaluation, this paper puts forward reference suggestion for the supervision system of national wetland parks.
