摘要
介绍了参考作物腾发量和实际作物腾发量的实时预报及修正方法 ,结合陡山灌区实际资料 ,分别针对主要旱作物和水稻建立了实时灌溉预报模型 ,并对模型各参数进行了率定 ,特别针对参考作物腾发量预报模型中 A0 的确定进行了分析 ,给出了更合理的 A0 取值方法。基于可视化语言开发灌溉配水实时决策支持系统 ,该系统界面友好 ,操作简单 ,实用性强 ,利于推广。
Methods of real time forecasting and amending daily reference evapotranspiration and actual crop evapotranspiration were introduced. The real time irrigation forecasting method and models were presented and the parameters in these models were calibrated based on data investigated in Doushan Irrigation Scheme. Especially, the methods for determine parameter A 0 in model of predicting daily reference evapotranspiration was further discussed and a new method was suggested in order to improve forecasting precision. A decision support system, which has friend interface and is easy to apply, for real time irrigation water allocation was also developed in this paper.
