The study of the constitutional principles of the functioning of the mechanism of administrative and legal regulation in the sphere of ensuring the ecological security of Ukraine is an urgent scientific problem, the solution of which can provide clear guidelines for its reform and improvement. The article analyzes the role and significance of the Constitution of Ukraine as the Fundamental Law in the aspect of ensuring the functioning of a holistic mechanism of administrative and legal regulation in the sphere of ensuring the ecological security of Ukraine. At the same time, the fact is stated that the Constitution of Ukraine laid the basic principles for the formation of such a mechanism in the sphere of ensuring ecological security as the leading type of national security of Ukraine. It is also noted that the Law of Ukraine “On Environmental Protection” was adopted before the Constitution of Ukraine came into force, but it was after the adoption of the Fundamental Law of Ukraine that the process of amending this Law and its gradual modification was significantly intensified. Such modification, in particular, concerned the formation at the legislative level of the status of subjects of power that carry out public administration in the field of ensuring environmental security. It is proved that since the Constitution of Ukraine at the time of its adoption was a progressive document that significantly outpaced the fundamental provisions that existed within the national legal system before the adoption of the Constitution of Ukraine, it is the Fundamental Law that should be the basis for reforming the mechanism of administrative and legal regulation in the field of ensuring the environmental security of Ukraine as a type of national security. All this made it possible to accelerate the processes of appropriate reform, relying on such constitutional values as stability, security and balance, which in the modern world serve as the foundation for the development of statehood, social progress and guaranteeing the vital interests of every person. Thus, today the Constitution of Ukraine as the Basic Law has laid a solid foundation in the system of regulating a wide range of various social relations. Among them, issues related to ecology, ecological balance and ecological safety occupy a leading place. Moreover, the Constitution forms such principles comprehensively, starting from the preamble and including all its other provisions. For example, the preamble of the Constitution of Ukraine, having a direct correlation with other provisions of the Basic Law, forms a significant basis for improving the mechanism of administrative and legal regulation in the field of ensuring the ecological safety of Ukraine.
