Abstract: To clarify the interaction between land-use change and ecosystem service, the traditional ecosystem service valuation model was modified using the adjustment coefficients of biomass factor and socio-economic factor to evaluate ecosystem service value (ESV) of 24 towns in Anxi County from 1999 to 2019, aiming to understand the ecological response to land-use change. The results showed that ESV of 24 towns in Anxi County decreased gradually during the study period, with a decrease of 0.004 to 0.295 million yuan. Forestland and cultivated land made the largest contribution to ESV, followed by grassland and water bodies, whereas the contribution of other land types were negative. ESV could be increased by converting other land types into forestland, but be decreased by converting other land types into orchard land area (mainly tea plantation). The chemical fertilizer-monoculture management pattern of ratooning tea plantation reduced ESV, while the ecological cultivation of tea plantation could effectively improve soil microbial diversity and soil fertility, and finally enhance ESV.
