Abstract:: The spatio-temporal changes and trade-offs of ecosystem service value, and the correlation between ecosystem service value and human activity intensity in forested counties were explored in order to promote ecological civilisation construction in forested counties in the future. It will provide a basis for the development and implementation of ecological protection and ecological restoration policies. The spatio-temporal changes of ecosystem service value in Cili County were analysed using the revised ecosystem service value estimation model. Correlation analysis and bivariate spatial autocorrelation analysis were used to estimate the trade-off and synergy between ecosystem services and human activity intensity, respectively. The results showed that:(1)In the Cili County, total ecosystem services increased. The contribution of forest to ecosystem service value was relatively high in the land use.(2)The region with the higher service value was mainly situated on the eastern, central, northwest and southern areas, whereas that of the lower service value was in the mideast; the service value in the central, southern and northwestern region obviously increased.(3)A synergetic relationship was dominant in Cili County and the ecosystem service value was negatively correlated with human activity intensity. In the past 40 years, Cili County has achieved a win-win situation of economic development and ecological protection. In the future, the ecological protection should focus on the ecological quality of forest land.
