The productivity of northeast spring wheat under climate change condition was predicted using AquaCrop crop model that was verified based on the measured data.The results showed that there was a better simulation effect on the biomass with the coefficient of determination(R~2)between the simulated and measured values being 0.957~0.997.In the early grain filling stage,the difference between simulated and measured grain accumulations was not obvious.The sensitivity of the AquaCrop model for water was greater than the temperature.Spring wheat productivity increased with the increase of CO_2concentration. AquaCrop model is feasible for spring wheat productivity simulation.
