Abstract: The guaranteeing of natural ecological security boundaries is a new development goal proposed by the Fifth Plenary Session of the 19th Central Committee of the Communist Party of China, and it is an important direction for ecological conservation in the future. However, current research about natural ecological security boundaries does not provide sufficient theoretical support for ecological conservation and restoration. Based on environmental management practices, the concept of natural ecological security boundaries has been analyzed and their meaning has been described from two perspectives, namely boundaries of spatial distribution and environmental management. The challenges faced when attempting to guarantee natural ecological security boundaries, including those related to ecosystem quality, the ecological space estate, and supervision capacity construction has also been described. Based on the analysis, further research focus on natural ecological security boundaries are recommend, which include the strengthening of basic theoretical exploration, optimizing of territory planning, and designing of ecological restoration systems. In addition, future management of natural ecological security could be advanced by the strengthening of top-level design, improving of the legal protection system, and coordinating of demands for ecological conservation and economic development.

Key words: ecological conservation, ecological security, boundary, environmental management
