Abstract: In recent years,the generalization of environmental public interest and the alienation of administrative power have become two major challenges to the construction of administrative rule of law in national parks in China.The multiplicity of the value of national parks and the uncertainty of decision-making guidance of administrative organs are the important reasons for the ineffective administrative protection of environmental public interests.In order to reverse this dilemma,it is necessary to establish the guiding position of Xi Jinping thought of ecological civilization and the principle of balance of interests at the top level of design,and scientifically define the connotation and extension of environmental public interest.At the level of system guarantee,we should,in accordance with the requirements of systematic governance,straighten out the administrative supervision system,strengthen the cooperative governance between departments and regions,improve the planning management system,and improve the supervision system of the rule of law,optimize the procuratorial public interest litigation and the central ecological environment protection supervision system,so as to create a new pattern of coordination and coexistence of environmental public interests and other legitimate interests under the guidance of legislation.

Key words: national park legislation, administrative protection, environmental public interest, balance of interests
