AquaCrop作物模型在黄土塬区夏玉米生产中的适用性评价
Applicable evaluation of crop model AquaCrop for summer maize production in Loess Plateau Region
摘要
Abstract
In order to evaluate its applicability of crop model AquaCrop in Loess Plateau Region,the model parame-ters were revised and validated based on the summer maize parameters recommended by Hsiao et al .The biomass in the maize growing season,the change procedure of evapotranspiration,harvest yield and aboveground biomass in 2003, 2004,2005,2007,2008 and 2010 in Changwu Region of the Shaanxi Province have been simulated,and carried out the comparison and analysis for the simulated with measured data .The results were showed that:In the six years,the adjust-ed determination coefficient Adj .R2 for simulated yield data and measured yield data was 0 .9270,the relative error was between -2 .479 to 1 1 .182 .The Adj .R2 for simulated and measured aboveground biomass was 0 .7842 .In this model, the effect of simulating yield was better than the aboveground biomass .In 2005 and 2008,the Adj .R2 for simulated and measured evapotranspiration were 0 .6229 and 0 .7973,respectively .Therefore,this model has a good simulation effect and important significance for the next optimal water management of summer maize in Loess Plateau Region .关键词
