Understanding and quantifying the dynamic features of local ecosystem services (ESs) integrating diverse assessment results form crucial foundations for regional ES management. However, existing methods objectively evaluating multiple ESs remain limited. Consequently, this research evaluates four key based on InVEST RUSLE models in Central Yunnan Province (CYP)-from 2000 to 2020: water yield (WY), carbon storage (CS), habitat quality (HQ), soil conservation (SC). It then constructs an Integrated Ecosystem Service Index (IESI) using principal component analysis (PCA). Additionally, study explores factors driving spatial divergence by employing optimal parameter-based geographical detector model (OPGD) at scale. The indicated that (1) IESI was effectively applied CYP could quantitatively comprehensively integrate ESs. (2) During period, showed increasing trends WY, HQ, SC, while CS a decreasing trend. (3) during period exhibited trend initially increasing. average values were 0.7338 2000, 0.6981 2005, 0.6947 2010, 0.6650 2015, 0.6992 2020. (4) A 4500 m × grid identified as scale detecting comprehensive service (CES) CYP, relief degree land surface (RDLS), slope, NDVI top three drivers q-values. This offers more scientific effective method CES. also provides analytical tool balancing use competition assessing effectiveness policy implementation.
