Based on the pilot ecosystem analysis of Qianjiangyuan National Park, the ecosystem services function value index system was determined; multiple methods such as market value method and shadow engineering method were used to evaluate the four major categories in the years 2005, 2010, 2015, and 2018 of the ecological services of Qianjiangyuan national park which are provision, regulation, culture, and support. Results show that the total value of the pilot ecosystem services in Qianjiangyuan national park had increased to 7430.11 × 10⁶ yuan, 9128.41 × 10⁶ yuan, 12,718.38 × 10⁶ yuan, and 15,539.99 × 10⁶ yuan for each category respectively. The regulation category has always been the core ecosystem services function in the national park, accounting for more than 40% of the value of the total services. The increase in the value of ecosystem services in the park was due to the implementation of ecological measures such as logging bans and people paying more attention to environmental protection.
