Jiamusi is situated in Heilongjiang Province, China, the center of Sanjiang Plain. The 1980s’ overplanting paddy fields resulted a decrease groundwater levels, scarcity resources, and frequent earth collapses. Examining safeguarding resources this region has emerged as crucial subject. In light this, paper uses remote sensing water balance method SWAT distributed hydrological model to calculate area. It also conducts scientific experiments by examining various factors, including rainfall, degree supply, soil type, land use. measured monthly runoff City’s Tongjiang Fuyuan hydrology stations was utilized establish parameters for model. A preliminary assessment distribution features shallow area conducted using two methodologies mentioned above, following results are reached: (1) Hydrological Station both had good modeling results, with R2 NS values 0.81, 0.77, 0.75, respectively. (2) works well assessing resources. Between 2010 2016 (two preheating years), Jiamusi’s average recharge 61.03 × 108 m3, recoverable amount 27.4 m3. (3) Based on balancing approach, exploitable quantity between 2008 23.94 while 53.2 (4) metropolitan core phreatic reservoir reserves, which progressively decline northeast southeast directions. falls southwest center. Songhua River’s main stream near City least volume reserves layer, area’s converge northwest, where surface makes up majority
