基于水分驱动的AquaCrop模型及其研究进展

介绍了AquaCrop模型的原理及基本参数，从模型的校验与应用两方面阐述了该模型的研究进展。指出目前仍缺乏实测数据验证AquaCrop模型对蒸发及蒸腾的模拟效果；AquaCrop模型在严重水分及盐分胁迫下模拟结果精度较差；已开展的模拟研究地域范围窄；由于缺少更复杂的生理子模块，AquaCrop模型不能很好解释水分胁迫对光合产物向籽粒运输分配过程的影响。为了提高模型的模拟精度并进一步延伸模型的应用范围，应完善模型水分及盐胁迫模块，并在较广范围内获取丰富的实测数据对模型开展进一步的校验研究。

AquaCrop model based on water-driven principle and its research progress

The theory, parameters and characteristics of AquaCrop model were introduced and its research progress was reviewed from the viewpoints of validation and application of the model. It was pointed that: the measured data of evaporation and transpiration were still lacked for the validation of simulating results of AquaCrop model; the performance of AquaCrop model was poor under severe water and salt stress conditions; The locations for model study were not diverse; Because of lacking of the move complicated plant physiological submodel, AquaCrop model was not able to account for water stress impact on biomass partitioning into yield. In order to increase the accuracy degree of AquaCrop model and extend its application range, it is necessary to get abundant data measured for diverse locations and perfect the module of water and salt stress.
