摘　　要：从水稻田水量平衡公式出发,推导出水稻灌溉用水预测公式,利用历史实测灌溉用水及同期降雨资料率定有关参数,根据降雨预测灌溉用水量。公式适用于种植结构不明的灌区。The irrigation water forecasting models of rice is presented in the paper based on water balance equation in rice farmland. The parameters are calibrated using historical irrigation water supply and rainfall data, then irrigation water demand of rice is calculated to forecast practical irrigation water amount according to predicted rainfall in the irrigation area. The presented formula can be used for irrigation area, where crop constitution is not clearly.
