Abstract: According to the theory of functional separation of powers,internal supervision of power is an important aspect of achieving the effectiveness of power.The internal supervision mechanism of ecological and environmental administrative power is an important part of the operation of national public power in the construction of ecological civilization.This institutional mechanism is currently mainly regulated by the partys internal regulations and institutional system,and lacks unified and clear legal provisions.The shortcomings in the rule of law are reflected in the need to improve institutional design,construct a mechanism system,and supplement normative basis.The legislative improvement and mechanism construction of internal monitoring of ecological and environmental administrative power should be realized through codification.At the technical level of legislation,with the goal of implementing the national environmental protection obligations stipulated in the Constitution,and through the guidance of the theory of functional decentralisation,the internal supervision mechanism of ecological and environmental administrative power should be taken as a safeguard system for the implementation of the local governments responsibility for ecological and environmental protection under the environmental code,and the specific rules should be uniformly constructed in the General Provisions.

Key words: compilation of the ecological environment code, functional separation of powers, national environmental protection obligations, internal supervision of power, administrative ecological and environmental regulation
