[Objective] We explored the spatiotemporal evolution pattern and driving factors of ecosystem service coupling coordination between supply and demand in the Jinsha River cascade hydropower project reservoir area, and provided decision-making supports for ecological management of hydropower project reservoir area. [Methods] Based on the data of land uses, population, GDP, NDVI and precipitation in the Jinsha River Cascade hydropower project reservoir area, market value method, coupled coordination degree model and geographically weighted regression model were used to study ecosystem service coupling coordination degree between supply and demand and its driving factors. [Results] The value of ecosystem service in the reservoir area reached 91.7 billion yuan in 2019, and the total value of ecosystem service increased by 680 million yuan during the study period. The spatial distribution of coupling coordination degree between ecosystem service supply and demand in the reservoir area was relatively stable. The regions of extreme maladjustment and severe maladjustment mainly distributed on the north bank of Jinsha River, while the regions of grudging coordination and good coordination mainly distributed on the south bank of Jinsha River. Vegetation cover had a positive driving effect on the coupling coordination degree between ecosystem service supply and demand in the Jinsha River Reservoir Area, population and relief amplitude had the negative driving effect, precipitation had the positive driving relationship to the north of the reservoir area, while the rest of the reservoir areas showed the negative driving effect. [Conclusions] This research showed that the spatial distribution of the coupling coordination degree was high in the south and low in the north and was affected by multiple factors. In the future, it is necessary to strengthen the study of ecosystem services in the reservoir area of hydropower projects.
