农田灌溉雨水集蓄系统设计研究

Study on the designing of the rainwater harvesting irrigation system

在分析雨水集蓄系统基本原理和计算方法的基础上,构建了包括降水序列分析子系统、集水量分析计算子系统、蓄水设施优化设计子系统、灌溉水量优化分配模型子系统和经济模型的农田灌溉雨水集蓄系统,并以陕西省礼泉县北部丘陵区为例,采用该系统对大田作物(小麦、玉米)雨水集蓄灌溉利用问题进行了分析,结果证明该系统具有一定的实用性。

The design of the rainwater harvesting system for irrigation has been developed.The system includes the analyzing subsystem of the sequential precipitation,calculating subsystem of harvested rainwater amount,optimizing subsystem of the runoff storing engineering,optimizing model subsystem of crop irrigation system and economic model.The application of the system for field crops (wheat,corn) in North Liquan,Shaanxi is summarized.The results indicate the system is practical.
