| 英文摘要 | Evapotranspiration (ET) is a critical component of agricultural water use and global climate systems. While the Y-SEBAL model, an improved SEBAL model based on the nonlinear relationship between net radiation flux and sensible heat flux, offers innovative capabilities for remote sensing-based ET quantification, its physical drivers and regional scalability across heterogeneous landscapes remain inadequately characterized. This study evaluates the performance of Y-SEBAL across China through multi-scale validation, a comparative analysis with widely available ET models (PML_V2 and MOD16), and mechanistic evaluation of its surface energy partitioning framework. Validation utilizing eddy covariance measurements from nine representative flux sites demonstrated strong agreement (average R = 0.78, average centered root mean square deviation (CRMSD) = 0.96 mm & sdot;d(-1)). At the national-scale, Y-SEBAL performed best in grassland ecosystems (R = 0.81) and plateau temperate semi-arid zones but systematically overestimated ET in the Qinghai-Tibet Plateau. Frequency distribution analysis ranked model performance as Y-SEBAL > MOD16 > PML_V2 in peak ET representation. Y-SEBAL's simplified stomatal resistance parameterization and strong coupling of surface energy components enhance turbulent heat fluxes under water-limited conditions, providing superior performance in water-constrained environments but introducing uncertainty in heterogeneous underlying surfaces. The framework advances ET quantification in transitional climate zones while highlighting trade-offs between process representation and regional scalability. |
