In this study, the surface water balance method was used to calculate the interaction between surface water and groundwater (SGW) in the Taoer River alluvial fan in Jilin Province, China, from 1956 to 2014. The automatic linear model was used to determine the key and non-key influencing factors, and correlation analysis was performed to evaluate their relationship with one another. River runoff and groundwater level were the key factors affecting the SGW interaction, and sand–gravel exposure in the fan was more conducive to SGW interaction. There was a positive correlation between runoff and SGW interaction, and the relationship between the groundwater and surface water levels was correlated and affected by groundwater exploitation and groundwater runoff. Groundwater exploitation and evaporation and precipitation indirectly influenced the SGW interaction by affecting the groundwater level and river runoff key factors, respectively, and were considered non-key factors.

本研究采用地表水平衡方法计算了1956年至2014年吉林省Tao尔河冲积扇中地表水与地下水之间的相互作用。使用自动线性模型来确定关键和非关键影响因素，并进行相关分析以评估它们之间的关系。河流径流和地下水位是影响SGW相互作用的关键因素，而风扇中的砂砾接触更有利于SGW相互作用。径流与SGW相互作用之间存在正相关关系，地下水与地表水位之间的关系与地下水开采和地下水径流相关并受其影响。
