Functional zoning is a key step for the integrated planning and scientific management of a national park. Selecting the Three-River-Source National Park (TNP) as the study area, this paper establishes an evaluation system including 13 evaluation indexes which are classified into four categories, namely: ecosystem services; potential distribution of key species habitats; ecological sensitivity; and ecological resilience through the comprehensive analysis on the regional eco-environmental features in the study area. The results of the comprehensive analysis, combined with the functions and requirements of management of national parks, indicate that TNP is divided into the first-level zone (the core conservation area, the ecological restoration area and the traditional utilization area) with definite targets of space management and the second-level zone with implementation of control measures. This method of functional zoning lays a solid foundation for the scientific planning of TNP; moreover, our study provides new insights into other national parks’ functional zoning.
