Leakage is important in groundwater cycle research and water resource management, the key to construct spatial distribution of aquitard. Influenced by natural anthropogenic factors, density boreholes restricts accuracy aquitard structure. This paper explores K-Nearest Neighbor (KNN) method multi-layer structure hinterland Songnen Plain, Northeast China, with limited boreholes, compare it Inverse Distance Weight (IDW) Ordinary Kriging (OK) methods evaluate leakage. The KNN needs first identify eigenvalue-k each layer, which used enhance trainset obtain testset a larger amount sample data enhanced, make prediction 3-dimensional more accurate than IDW OK. aquitrad obtained different from OK, thickness difference 3.53%-54.00%, area 2.28%-23.91%, leakage can be up 24.51%. also has high degree identification edges, help prevention pollution. results provide guidance for balance analysis, borehole engineering design, resources management exploitation.
