Abstract: Administrative law enforcement is an important aspect of the legalized construction of local environment, but it faces many
difficulties in the process of implementation. In the Erhai Lake region, during the process of enforcing environmental laws, there are
problems such as unclear division of enforcement authorities, flawed basis for law enforcement, and lack of expertise in the law
enforcement teams. We should start with changing the concept of law enforcement, perfecting laws and regulations, integrating forces in
law enforcement, strengthening the building of professional groups, giving full play to public participation and social co-governance so
as to solve the problems in the protection of Erhai Lake.

Key words: protection of Erhai Lake, enforcement of environmental law, law enforcement authority, basis for law enforcement
