The Yangtze River Basin serves as a vital ecological barrier in China, with its water conservation function playing critical role maintaining regional balance and resource security. This study takes the Minjiang (MRB) case study, employing fractal theory combination InVEST model SWAT-BiLSTM to conduct an in-depth analysis of spatiotemporal patterns conservation. research aims uncover relationship between dynamics watershed capacity ecosystem service functions, providing scientific basis for protection management. Firstly, is introduced quantify complexity spatial heterogeneity natural factors such terrain, vegetation, precipitation Basin. Using model, evaluates functions area, identifying key zones their variations. Additionally, employed simulate hydrological processes basin, particularly impact nonlinear meteorological variables on responses, aiming enhance accuracy reliability predictions. At annual scale, it achieved NSE R2 values 0.85 during calibration 0.90 validation. seasonal these increased 0.91 0.93, at monthly reached 0.94 0.93. showed low errors (RMSE, RSR, RB). findings indicate significant differences Basin, upper middle mountainous regions serving primary areas, whereas downstream plains exhibit relatively lower capacity. Precipitation, terrain slope, vegetation cover are identified main affecting changes having notable regulatory effect Fractal dimension reveals distinct structure which partially explains geographical distribution characteristics functions. Furthermore, simulation results based show increasingly climate change human activities frequent occurrence extreme events, particular, disrupts posing greater challenges Model validation demonstrates that SWAT integrated BiLSTM achieves high capturing complex processes, thereby better supporting decision-makers formulating management strategies.
