Since ancient times,there are two modes and paths of environmental governance in China. One is the environmental governance policy implication in the context of environmental history; the two is the demand of environmental governance system in the context of environmental ethics. From the perspective of the current judicial dimension of China's environmental governance,there are some problems such as the difficulty to coordinate the promotion of environmental policies,and the problem of the renewal and perfection of the environmental justice system. The implementation of the Opinions on Accelerating the Construction of the Ecological Civilization provides guidance for the policy coordination and system optimization of China's environmental governance. Policy coordination of the environmental governance needs to follow the basic principles of environmental protection beyond. The requirement for the main body is to understand the environmental legal policies,and the specific operation is the criminal policy analysis of environmental governance and the overcome of some obstacles. The realization of the legal policies of environmental governance is an environmental law system project,and it needs to realize the optimization and upgrading of the related system of environmental management. This system optimization is based on the guiding principle of the core value of ecological integrity,from the two systems of environmental entities and environmental procedures,to integrate the existing management technology and practice. In the aspect of entity,the realization of environmental governance laws and policies requires the improvement and perfection of the linking mechanism between relevant laws and regulations. In the aspect of procedure,we should emphasize on environmental justice studies and corresponding classification of procedure guarantee mechanism.
