Recreation is an important cultural service function of ecosystems in the national parks. Assessment on recreation potential use of the national parks is the key to the synergistic enhancement of ecological protection and national recreation welfare. This paper constructed an index system in six dimensions with 25 indicators for evaluating the recreation utilization potential of Qianjiangyuan National Park in terms of recreation resource value, recreation landscape quality, recreation ecological environment, recreation utilization conditions, national park community and recreation utilization management, and carried out a multi-method integration of the Delphi method, analytic hierarchy process (AHP), questionnaire survey, semi-structured interview, remote sensing (RS), and geographic information system (GIS) for the national park recreation use potential evaluation research. The results showed that recreation use in the national parks can be evaluated in six dimensions: recreation resource value, recreation landscape quality, recreation ecological environment, recreation utilization conditions, national park community and recreation utilization management; the areas of the potential areas of recreation use I-IV in Qianjianggyuan National Park were 16.18 km², 53.44 km², 71.52 km² and 38.90 km² respectively, accounting for 8.99%, 29.68%, 39.72% and 21.61%. Among them, the relatively high potential Class III and IV areas were distributed in the form of bands and blocks in the Grand Canyon of Qianjiangyuan, Qixi Reservoir, Gaotiankeng-Kukeng-Huitai Mountain area, Dayuantou-Daheng ancient village area, i.e. the recreation display area and traditional use area where recreation resources were concentrated and ecological protection was effective. Class I and II areas with relatively low potential were mainly distributed in ecological conservation areas and traditional agricultural cultivation areas in He Tian Township and Su Zhuang Township. The results can provide theoretical support for the construction of the ecotourism suitable area in Qianjiangyuan National Park. It is suggested to optimize the recreation use environment through rational functional analysis, facility enhancement, landscape management, ecological monitoring, and space management; to develop eco-tourism products, eco-vacation tourism products, outdoor recreation tourism products, science popularization products, festival products, food tourism products, study tourism products and other recreational products for promoting the ecological protection and regional high-quality development of national parks; to guarantee community income and common prosperity in the national parks through the establishment of the franchise implementation program, the fair and orderly bidding and evaluation mechanism, and the completion of the franchise system; to establish and improve the adaptive management mechanism for recreation use in national parks in terms of completing the planning of recreation use in national parks, strengthening the input and usage and supervision mechanism of special funds for recreation use in national parks, enhancing the management of visitors, perfecting the community's participation in the mechanism of recreation use, and reinforcing the monitoring of ecological risks of recreation environments.
