| 摘要: |
| 为评估AquaCrop模型在黑龙港流域模拟冬小麦-夏玉米水分利用与作物产量的适用性，根据田间试验数据和FAO提供的参数值，对AquaCrop模型进行模型非保守性参数的本地化校准和验证。结果表明，AquaCrop模拟冬小麦冠层覆盖值和实测值的归一化均方根误差（NRMSE）为15.90%，模拟产量与实测产量之间的NRMSE为4.23%；模拟夏玉米冠层覆盖值和产量值与相应实测值之间的NRMSE分别为11.59%和11.69%。本研究校准所得参数对黑龙港流域典型站点有较好的适应性，校验后的AquaCrop可以用于黑龙港流域冬小麦-夏玉米水分管理、产量潜力等相关研究。 |

| Abstract: |
| In order to verify the applicability of AquaCrop model for simulating water use and crop yield of winter wheat-summer maize in the Heilonggang River Valley,both the field test data and parameter values provided by FAO were input into the model to calibrate and verify non-conservative parameters.Results showed that the normalized root mean square error(NRMSE)of winter wheat canopy coverage between simulated value and measurement was 15.90%,the NRMSE between simulated yield and measured yield was 4.23%.For summer maize,the NRMSE of canopy coverage and yield between simulated values and measurements were respectively 11.59% and 11.69% indicating that the parameters obtained by calibration had better adaptability to Wuqiao County.In conclusion,the developed AquaCrop model could be applied to study the relationship between water management and yield of winter wheat-summer maize in the Heilonggang River Valley. |
