In the context of building the rule of law in China and a beautiful China in the new era, bringing the Chinese-style modernization of harmonious coexistence between man and nature into the track of the rule of law has the basic guarantee function and strategic support function for taking the path of Chinese-style modernization and building a socialist modern power in an all-round way. The construction of Chinese-style modernization of harmonious coexistence between man and nature on the rule of law track demonstrates the ecologically good laws and good governance combining formal rule of law and substantive rule of law. It also embodies the pursuit of harmonious development values of coexistence and co-prosperity between man and nature and creates a new form of human ecological rule of law civilization that embodies the complementary effects of socialist ecological civilization and rule of law civilization with Chinese characteristics. The Chinese-style modernization is guided, standardized and guaranteed by the rule of law for the harmonious coexistence between man and nature, and its main objectives are to build a complete norm system, an efficient implementation system, a strict supervision system and a strong guarantee system of the rule of law. The construction of this rule of law system is a complex project. While significant progress has been made, there are still many challenges and issues to address. For example, the system and completeness of ecological environment legislation is not enough, and its coordination with the constitution, other departmental laws and inner-Party ecological civilization regulations is not enough; The eco-environmental law enforcement system has not yet reached the goal of benign and efficient construction, and the eco-environmental justice system has not really formed a rational and systematic "green justice" system. Problems are also reflected in the poor working mechanism of ecological environmental protection supervision between central and provincial level and the lack of joint efforts between national supervision and social supervision. In the field of ecological legal guarantee system construction, the political and organizational guarantee, the team and talent guarantee, and the material condition guarantee need to be improved and optimized. In order to continue making progress, it is necessary to adopt a problem-oriented approach, maintain and strengthen Party leadership, establish a mechanism for top-down and bottom-up interaction, utilize a systemic and coordinated methodology of rule of law, and focus on key areas such as filling gaps in ecological and environmental legislation, improving the enforcement of ecological and environmental laws, advancing specialized environmental and resource judicial proceedings, and increasing publicity and education of the ecological and environmental rule of law. It is also necessary to build a Chinese indigenous legal knowledge system that promotes harmonious coexistence between man and nature and to consistently adhere to higher standards and stricter requirements in advancing the Chinese-style modernization of harmonious coexistence between man and nature on the track of the rule of law.
