水量订单制度下黄河下游灌区水资源实时分配模型及管理软件开发

The management system for real time allocation of the irrigation water resources in the lower reaches of the Yellow River according to the present water rules

针对黄河下游引黄灌区水量订单随意性大、水资源利用率低的问题,本文紧密结合当前调度管理制度,基于实时灌溉预报与模糊聚类理论,提出了黄河下游灌区水资源实时分配管理模型,模型包括考虑土壤墒情、雨水资源及天气情况影响的作物需水预测模型和灌区实时水量订单模型两部分内容。在典型灌区,进行了模型的应用,并开发了相应的水资源管理软件;应用结果的合理性表明了模型的正确性,该模型可广泛用于黄河下游灌区的用水管理和调度。

Aimed at the liberty of water order and the low water use efficiency,with close linking to the management rules of the Yellow River water and based on real-time irrigation forecast and the fuzzy cluster theory,a management system is developed for allocation of the irrigation water resources in the lower reaches of the Yellow River,including crops water demands sub-model and real-time water order sub-model.The factors of soil moisture,rainfall and weather types are thought of in the crops water requirement sub-model.The management systems and the software are used in Qucun irrigation area,and the results are reasonable.The system can be used to improve the water use efficiency and give suggestions to the operators.
