The protected area plays an important role in maintaining ecological balance and realizing ecosystem service function. There are differences in the supply of main function of ecosystem services in different types of nature protected area. The legislative work of Act of Nature Conservation Areas is based on the typification of nature protection land in theory. And the corresponding planning and construction, operation management and other aspects of the system should be built. Therefore, based on the difference of ecosystem service function supply, the current overlapping and lack of systematic types of natural conservation areas can be transformed into four types:national parks, nature reserves, nature parks and small nature conservation areas. The legal system of "one basic law and four typed regulations" will be built. The governance of natural conservation areas can be strengthened by institutionalizing public law and private law system tools.
