摘　　要：在AquaCrop作物模型数据库组建的基础上,应用该模型对东北春小麦冠层生长进行模拟。结果表明,除2010年呼玛地区模拟值低于实测值外,其余年份和地点的模拟值均高于实测值,IoA在0.726~0.995之间,模拟值与实测值的一致性较为理想;AquaCrop模型能较好反映正常年份下春麦生育活动,模型模拟情况与各地观测到的冠层发育情况较为一致。但对极端气候下的春麦冠层发育的模拟效果较为一般。在以后的研究中,需进一步对气象参数做出修正,以更好地应用于小麦的生产和预测。The results indicated that the simulated values of the rest of the year were generally higher than the measured values in addition to the Huma region.The consistency of simulated values and measured values was ideal,which IoA was 0.726to 0.995.The simulated and measured values of other region have reached a consistent in canopy development,and the AquaCrop model can reflect spring wheat reproductive activities in average years.But the development of spring wheat canopy was general under extreme weather,which was a problem to improve in AquaCrop.In order to better use in producing and forecasting the wheat,we need to make a further correction to the meteorological parameters in the future research.
