摘要

目的叶面积指数(leaf area index，LAI)作为生态系统水循环过程模拟研究的关键参数，其快速动态模拟可解决土壤水-汽-热-气耦合模型STEMMUS(simultaneous transfer of energy，mass and momentum in unsaturated soil)只能使用固定或实测LAI作为输入参数的局限性。方法将EPIC模型中的“植物叶面积发育子模块”与STEMMUS模型耦合，采用2019年和2020年子洲县山地苹果试验示范基地苹果生长条件下实测的果树蒸腾、土壤水分和土壤温度数据对模型进行率定与验证，以评估耦合模型在黄土高原的适用性。结果通过优化植物生长参数，耦合叶面积发育子模块后的STEMMUS模型对苹果树蒸腾耗水过程的模拟精度显著提高，率定年和验证年的归一化均方根误差(NRMSE)和平均绝对误差(MAE)分别从原模型的40.2%、61.9%和0.52、0.64 mm/d降低到耦合模型的30.0%、33.2%和0.42、0.38 mm/d。同时，耦合模型可较好地模拟苹果园的土壤水热动态过程，在率定期和验证期模拟土壤水分体积分数和土壤温度的NRMSE分别为1.4%~32.9%和2.9%~9.5%，MAE分别为0.13~4.26 cm3/cm3、0.34~1.49 ℃。结论模拟值与实测值吻合度较高，表明耦合模型可准确描述黄土高原苹果园果树叶面积动态生长和生态水文过程，研究结果可为黄土区果园生态水文过程的研究提供技术支撑。

Abstract

ObjectiveAs a key parameter in the simulation study of ecosystem water cycle process

rapid dynamic simulation of leaf area index (LAI) can solve the limitation that the coupled soil water-vapor-heat-air model STEMMUS (simultaneous transfer of energy

mass and momentum in unsaturated soil) can only use fixed or measured LAI as an input parameter.MethodsIn this study

the "plant leaf area development sub-module" in EPIC model was coupled with the STEMMUS model

and the model was calibrated and validated using the measured transpiration of apple trees

soil moisture and soil temperature data under the growth conditions of apple trees in the mountain apple experimental demonstration base of Zizhou County in 2019 and 2020

so as to evaluate the applicability of the coupled model on the Loess Plateau.ResultsBy optimizing the plant growth parameters

the coupled leaf area development sub-module of the STEMMUS model significantly improved the simulation accuracy of the transpiration and water consumption process of apple trees

with the normalized root mean square error (NRMSE) of the calibration and validation years decreasing from 40.2% and 61.9% in the Original model to 30.0% and 33.2% in the coupled model

respectively

and the mean absolute error (MAE) decreasing from 0.52 and 0.64 mm/d to 0.42 and 0.38 mm/d

respectively. Meanwhile

the coupled model could better simulate the soil hydrothermal dynamic processes in apple orchards

and the NRMSE of simulated soil water content and soil temperature during the calibrated period and validation period ranged from 1.4% to 32.9% and 2.9% to 9.5%

respectively

and the MAE ranged from 0.13 to 4.26 cm3/cm3 and 0.34 to 1.49 ℃

respectively.ConclusionThe high agreement between the simulated and measured values indicates that the coupled model can accurately describe the dynamic growth process of apple tree leaf area and the ecohydrological process of orchard on the Loess Plateau

and this study can provide technical support for the research of the ecohydrological process of orchard in loess area.
