The Applicability and Application of AquaCrop Model
摘要
Abstract
AquaCrop model driven by water is a new crop simulated model recommend by FAO. In order to evaluate its applicability in North China , this irrigation experiment for summer maize was conducted in two successive year (2009-2010) in Daxing station in north china plain, of which, the measured date in 2010 was used to calibrate the crop parameters, and the other was used to test it. Then the OTA method was a-dopted to analyze sensitivities of the model parameter. The validation results showed that the AquaCrop model could preferably simulate the yield, biomass and the dynamic changes of canopy cover and soil moisture of summer maize. The relative error of simulated yield and biomass is 0%～15. 6%. For simulated the process of canopy cover and soil moisture, the minimum correlation coefficient of determination were 0. 657, 0. 959, the maximum of root mean square error 5. 837%, 1. 873 m3/m3 and the minimum model efficiency was 0. 670, 0. 956 respectively. The results of the sensitivity analysis showed that the day to CCx, the start date of canopy senescence, field capacity, wilting moisture content ,initial moisture content a-mong all of model parameters had the most significant influence on the simulation result, the sensitivity degree was 0. 161 4～0. 398 2. It marked the good applicability and the broad development prospects of AquaCrop model in this area.关键词
