Xülasə:
Adaptive water management in China’s North China Plain is hamstrung by chronic groundwater overdraft and increasingly volatile monsoon rainfall. Most assessments, however, still treat farmer behavior and hydrologic dynamics in isolation. This study develops a new socio-hydrological framework that couples a variable-infiltration capacity model with MODFLOW-NWT (VIC–MODFLOW) and a micro-founded discrete-choice behavioral module. The behavioral component is calibrated on a 1,204-household survey across 36 irrigation districts using random-utility estimation and prospect-theory loss aversion parameters. Reservoirs are co-optimized with a multi-objective rule curve that balances supply reliability and ecological flows. Downscaled CMIP6 projections (SSP2–4.5 and SSP5–8.5, 2025–2045) drive the coupled system to evaluate irrigation, crop choice, and pumping responses under water-pricing, efficiency, and quota policies. The integrated model reproduces observed dynamics credibly: monthly streamflow NSE = 0.72, groundwater head RMSE = 1.31 m, and out-of-sample hit rate for irrigation decisions = 78%. Five headline findings emerge. First, absent new policy, mean annual groundwater storage declines by 10.6 ± 2.4 km3 by the 2040 s, with dry-year losses concentrated in Hebei piedmont cones. Second, warmer summers (+0.9 to +1.6 °C) increase crop evapotranspiration by 3–6%, raising peak-season pumping by 11% despite a − 3% change in mean precipitation. Third, a 20% on-farm efficiency upgrade combined with tiered volumetric pricing reduces agricultural withdrawals by 17% (95% CI: 13–21%) while maintaining net farm income through input savings. Fourth, endogenous crop switching shifts 12% of wheat area toward maize and peanuts, cutting blue-water demand by 8% and stabilizing yields in heat-stress years. Fifth, adaptive reservoir rules recover 0.7 km3 yr1 of environmental flows to downstream rivers without compromising municipal reliability. These results demonstrate that pairing targeted efficiency incentives with progressive volumetric pricing and adaptive reservoir operation can curb groundwater depletion while safeguarding farmer livelihoods and ecological flows.
