The evaluation of ecosystem service functions is a hot issue across the world as it is related to human well ̄being. Water conservation function has become one of the most important service functions and plays a key role in ensuring regional ecological security and sustainable development. Based on the InVEST modelꎬ this study quantitatively evaluated the water conservation function of Heilongjiang Province from 2000 to 2020. We analyzed the dominant influencing factors of the spatial differentiation characteristics of water conservation function changes in the past two decades through geographical detectorꎬ and combined geographically weighted regression to capture the spatial variation of the driving factors. The results showed that: (1) the average water conservation amount of the province increased from 13.81 mm / m to 20.29 mm / m from 2000 to 2020ꎬ and the total water conservation amount increased by 46.92%. (2) Climate change was the main driver of
