Taking Zhongtian Tianchi Nature Reserve as the research area and according to the ecological service value data of different terrestrial ecosystems in China developed by Xie Hedian and other related data, combining with the actual situation of the nature reserve and the field investigation results, the ecological service function of Zhongchi Tianchi Nature Reserve The value of a comprehensive assessment. The results showed that the total ecosystem service value provided by Zhongtian Tianchi Nature Reserve was 58.4536 million yuan per year, accounting for 61.95% of the county’s total forest output value and 0.43% of the county’s GDP. In the annual ecological service value , Accounting for 18.31% of the total, followed by climate control accounting for 14.46%, biodiversity conservation accounting for 14.18%, water conservation accounting for 13.93%, gas regulation accounting for 12.33%, raw material production accounting for 10.04%, waste treatment 9.15%, 4.94% of entertainment culture and 2.66% of food production. Among the different types of ecosystem in the nature reserve, forest ecosystems and farmland ecosystems contributed most to the total ecosystem service value, accounting for 82.45% and 15.34% respectively.
