N2 - Water conservation is one of the most important ecosystem functions. This study uses the InVEST model to examine the water conservation function of the Qilian Mountain National Park (QMNP), an important water supply area in northwest China. We analyzed the spatiotemporal water conservation patterns of QMNP from 1988 to 2019. It showed that the water conservation capacity in QMNP has increased over the past 32 years, reaching a peak of 6.495×108 m3 in 2019. The area with an increased water conservation capacity is 12 times larger than the area with a reduced capacity. We also examined how climatic, land-use, vegetation coverage, and topographical factors influence water conservation functions. We found that precipitation is the main climatic factor in water conservation. The water conservation function also varies with land-cover type, with forests having the highest capacity, followed by grasslands. Lastly, topographical factors, including altitude and slope, also shape the spatial patterns of water conservation functions in QMNP.
