National park combines the functions of natural ecosystem protection and education, recreation and other social cultural functions. It is one of the potential activity places for natural, experiential and curriculum study travel, while study travel provides a reference path for the realization of the educational and recreational value of the national park. Following the principles of independence, comprehensiveness, scientificity and operability, four factors including education value, recreation value, environmental conditions, and related facilities and services were selected to construct the study travel development suitability evaluation system for national park based on the analysis framework of internal value-external condition, and an empirical analysis is made with Qianjiangyuan National Park. The results show that the utilization of study travel in national park should firstly consider educational value, improve education, recreation and other related facilities and services while taking environmental conditions such as environmental carrying capacity and stakeholder attitudes into account, and finally consider the value of recreation. The study travel utilization in Qianjiangyuan National Park has good educational and recreational value bases, and the primary and secondary school students' study travel needs and stakeholders' support attitudes provide external condition guarantee, but facilities and services in education, transportation and safety need to be improved. The research results can provide planning and management guidance for the use of study travel in national parks and other venues.
