Ecological protection red line（EPRL）system is an important policy instrument to promote the development of ecological civilization in China. Specifically，the boundary management of EPRL is of great concern. The concept of EPRL has a close relationship with the existing theories such as systematic conservation planning，system dynamics，landscape ecology，sustainable development and green economy. From the practical point of view，the existing work focuses on the provincal EPRL rather than regional（watershed）EPRL. Furthermore，the planning of EPRL is of great concern while the management of EPRL is less important. The conflict between EPRL and other plans is a new problem，and the authority responsible for EPRL management is not clearly specified. It is proposed to further improve the legal system，institutional arrangement and implementation of the EPRL system，aiming to effectively promote the boundary management of EPRL in China.
