decline in some places [4]. The groundwater level of Jiamusi City needs to be repaired immediately [5]. The calculation and evaluation of groundwater resources form the data support and premise for putting forward the restoration plan, so this paper evaluates the groundwater resources in the Jiamusi area under this background. In recent years, there have been a lot of studies on groundwater resources at home and abroad. [PERSON] [6] used the soil water balance and chloride ion mass balance methods to estimate groundwater recharge in Ethiopia's Akaki Basin. Based on the study results, [PERSON] said the maximum recharge value of the basin can be represented by the average recharge value determined by the soil water balance method and the chloride ion mass balance method. In addition, [PERSON] [7] used the same method to estimate the recharge of the Alcalozo aquifer system in Spain and conducted an uncertainty analysis of the results of both methods. [PERSON] et al. evaluated groundwater recharge in Minnesota using the unsaturated zone water balance, groundwater dating, groundwater table fluctuation methods, and regional regression recharge model (RRR). They then compared and evaluated the charges obtained using the different methods. [PERSON] et al. combined the soil water balance model with the groundwater table fluctuation method to strengthen and verify the evaluation results of groundwater recharge in the upper Danube basin. [PERSON] et al. [8] selected groundwater recharge evaluation methods, such as the water balance, saturation zone Darcy's law, and groundwater level fluctuation methods, according to the actual situation of the study area and estimated the average annual groundwater recharge rate in Ordos Plain, Inner Mongolia. Although a large number of studies have produced a large number of results, they have all been derived using traditional formulas. Because the field investigation is time-consuming and laborious, and the problems, such as a lack of monitoring points in the steep and changeable terrain, are difficult to solve, the evaluation results are relatively biased. Therefore, this study selected Jiamusi City as the research object [9] and used the SWAT model and remote sensing water balance method to simulate groundwater resources in this area [10; 11].
