The Three-River regions，as a crucial water source conservation area in China，plays a crucial role in maintaining the regional hydrological and climatic stability through its extensive highland wetlands. Considering the competitive interaction between soil moisture anomalies and precipitation feedback mechanisms under differ‐ ent environmental conditions，this study conducted control and sensitivity experiments based on the WRF meteo‐ rological model，combined with the CTP-HIlow framework and CAPE index，to assess the precipitation response under soil moisture anomaly conditions. The study preliminarily analyzes the impact characteristics and feedback mechanisms of soil moisture anomalies on regional weather，particularly precipitation processes. Specifically， based on transient simplified evaporation experiments and inversion methods，the WRF simulation incorporated hydrological measurement data from multiple soil samples collected within the study area. The results show that the hydraulic properties of wetland soils significantly influence surface thermal properties and energy distribu‐ tion. The soil hydraulic parameters obtained using the simplified evaporation method significantly improved the model’s simulation of latent heat flux，sensible heat flux，surface temperature，2-meter air temperature，and 2- meter specific humidity. Soil moisture anomalies have a significant impact on short-term precipitation processes. Under conditions of soil moisture anomalies，both CAPE and CTP values significantly increase，while HIlow val‐ ues decrease，accompanied by an increase in atmospheric instability and water vapor content，leading to a clear positive feedback response in precipitation. In contrast，under dry anomaly conditions，CAPE and CTP values slightly decrease，while HIlow values increase，accompanied by reduced atmospheric instability and decreased wa‐ ter vapor content，with precipitation showing no clear feedback to soil moisture. The hydraulic characteristics of wetland soils，through regulating surface energy distribution and water vapor flux，significantly affect precipita‐ tion processes at both local and regional scales. Especially under soil moisture anomaly conditions，the hydrologi‐ cal regulation effect of wetland soils plays a crucial role in precipitation feedback mechanisms，further highlight‐ ing their key position in maintaining regional hydrological and climatic stability.
