摘　　要：针对目前灌区灌溉预报存在的问题,考虑灌区土壤水分和影响土壤水分变化的因子的空间变异性以及预报的实时性,提出了灌区实时灌溉预报模型。以江苏省某灌区为例,对灌区实时灌溉预报模型进行了验证。结果表明,预报精度和应用性得到了较好的统一。Aiming at the existing problem of current irrigation forecasting, a real-time forecast model of irrigation schedule in irrigation districts was established, which considered spatial variation of soils moisture and its affecting factors. The model has been tested in an irrigation district of Jiangsu province, and the result showed that the model could provide both high precision and good practicability.
