Abstract: The Minshan area of the giant panda national park is the area with the largest number of giant pandas and local populations. Based on the land use data of three periods 2000, 2010, and 2020, the improved equivalent factor method was used to measure the regional ecosystem service value of and analyze the characteristics of temporal and spatial evolution. The results showed that from 2000 to 2020, the total regional ecosystem service value continued to rise. Affected by the Wenchuan earthquake,the growth rate slowed down from 2000 to 2010. Through natural restoration and artificial protection, especially the implementation of the pilot work of the giant panda national park system, the growth rate increased from 2010 to 2020. In terms of spatial distribution, the value of ecosystem services showed an overall pattern of high in the east and low in the west. The ecological protection of the Minshan area of the Giant Panda National Park had achieved remarkable results. The ecological environment service functions had been continuously improved, and the ecosystem service value had continued to increase.
