摘要
作物水分生产函数的确定是农业水资源优化配置的关键。该研究采用农业水文生态系统模型(Agro-Hydrological&Chemical and Crop systems simulator, AHC)与基因表达式编程(Gene Expression Programming, GEP)相结合的方法构建作物水分生产函数。以河套灌区3种主要作物(葵花、玉米、小麦)为研究对象,采用AHC模型模拟作物产量等,构建基于GEP算法的作物水分生产函数,探讨考虑盐分胁迫的作物水分生产函数构建的思路与方法。结果表明:1)作物模拟产量与地下水埋深、地下水矿化度和灌水量等因素有关。2)构建作物水分生产函数的最优输入因子组合为地下水埋深、灌溉量、蒸散发、地下水矿化度、土壤根层盐分对作物胁迫因子、土壤根层含水率。3)应用作物水分生产函数估算不同灌溉定额条件下作物产量(预测产量),并与AHC模型计算的产量(模拟产量)进行比较,玉米、葵花、小麦预测产量与模拟产量具有很好一致性,其决定系数分别是0.96、0.93、0.96,平均相对误差均小于5%,满足计算精度要求。因此,该研究所构建的作物水分生产函数可以较准确地估算盐分胁迫下作物产量,为农业节水与灌溉水高效利用提供科学参考。
