摘　　要：使用AquaCrop模型与WOFOST模型对哈尔滨地区春小麦生长进行模拟,以春小麦的地上生物量和产量及生育期土壤体积含水量为指标,对比分析两个模型的模拟精度。结果表明:使用经过校正的两个模型均能够较为准确地模拟哈尔滨地区春小麦的生长发育情况及产量形成,观测值与模拟值一致性较好,误差均在合理范围内。在非正常年际AquaCrop模型模拟结果与实测结果偏差较大,说明该模型适合于正常年景的作物生长模拟,WOFOST模型适应性更强。在对2011年土壤水分含量的模拟中,两个模型观测值与模拟值总体趋势相同,误差均在合理范围内。总体来说,经过修正和校准后的AquaCrop模型与WOFOST模型均适合寒地春小麦的模拟研究。The main object of the study was analyzing the accuracy of the two models AquaCrop and WOFOST which were used for simulating the growth of spring wheat in Harbin based on biomass, yield and soil volume moisture content. The results indicated that the spring wheat growth and yield formation could be simulated accurately with the two optimized models. What＇s more, the values of observation and simulation value were closer and the error was creditable. The simulation results of AquaCrop model exhibit more difference with the measured results in abnormal year which revealed that the model was suitable for the crop growth in normal year while the WOFOST model showed more adaptability. The observation values of soil moisture content in 2011 were consistent with the total trend in the two models used in the research, also the error was creditable. In general, the optimized models AquaCrop and WOFOST were suitable for the cold spring wheat simulation research.
