Aims: There is a close relationship between biodiversity and ecosystem services. This study seeks to clarify the complex relationships and feedback mechanisms experienced between biodiversity and ecosystem services.

Method: Based on the spatial distribution pattern of species, this study utilized the MaxEnt model and Zonation software to evaluate the biodiversity of the Wujiang River Basin and applied the InVEST (integrated valuation of ecosystem services and tradeoffs) model to account for various ecosystem services. The study also used the random forest and partial dependence plot (PDP) machine learning models to analyze the relationship between biodiversity and ecosystem services in the Wujiang River Basin.

Results: The results showed that the biodiversity in the northeast of the Wujiang River Basin exhibited a distribution pattern of high, while in the southwest, the distribution pattern was low, with the downstream > midstream > upstream. In 2020, the Wujiang River Basin water supply was 810.57 mm/m2; the food supply was 735.08 kg/ha; carbon fixation was 134.00 Mg/ha; water conservation capacity was 227.98 mm/m2; soil conservation capacity was 401.30 t/ha, and the habitat quality was 0.68. Water supply, accounting for 66.24%, and water conservation, accounting for 44.72%, had relatively high contributions to biodiversity. Except for food supply, an ecosystem service that relies on human activities, all other ecosystem services positively correlated with biodiversity.

Conclusion: The study indicate that ecosystem services influenced strongly by climate and human activities drive changes in biodiversity, but biodiversity is a regulatory factor of some importance for ecosystem services that depend on biological functions.
