The Integrated Valuation of Ecosystem Services and Trade-Offs (InVEST) model with the distributed hydrological Soil Water Assessment Tool (SWAT) were implemented. SWAT quantifies visualizes water production groundwater reserves in Mudanjiang River Basin, employing runoff modulus method to calculate recharge basin. This study aims assess model’s applicability cold basins subsequently analyze distribution characteristics, reserves, exploitable volume. It serves as a reference for judicious allocation resources preservation local aquatic ecosystem. indicates following: (1) Utilizing monthly data from Mudan hydrologic station, simulation calibration conducted, yielding determination coefficient (R2) 0.75 Nash–Sutcliffe efficiency (NS) 0.77, thereby satisfying fundamental scientific research criteria. yield predicted by InVEST aligns closely bulletin region. (2) module indicate that average annual during period was 6.725 billion m3, an depth 148 mm. In 2018, characterized ample supply, output at its peak, 242 2014, recorded merely 16 (3) Throughout period, flow 4.2 whereas reserve 24.13 (108 m3·a−1). 2013, maximum 38.42 m3·a−1), while minimum 2014 2.36 suggesting region predominantly experiencing sustainable exploitation. (4) mean is 0.28 L/(s·km2), peak 15.4 m3·a−1) 2013 lowest just 3.2 2011.
