摘要
针对南方多水源灌区灌溉用水量统计存在水源众多、灌区取用水系统结构复杂、灌区水资源功能多样等特点,该文提出在灌区供、用、排等主要水循环节点建设用水计量监测设施,进而结合灌区水循环模型和农业灌溉用水量分析统计模型分析来确定灌区农业用水量的方法,实现南方多水源灌区农业灌溉用水量直接量测与模型计算有机结合。
In view of the characteristics of irrigation water consumption statistics in multi-water source irrigation areas in South China,such as numerous water sources,complex structure of water intake system and various functions of water resources in irrigation areas,this paper proposes to build water measurement and monitoring facilities at the main water circulation nodes of irrigation areas,such as water supply,use and discharge,and then determine the agricultural water consumption in irrigation areas by combining the analysis of water circulation model and agricultural irrigation water consumption analysis and statistics model.The method realizes the organic combination of direct measurement and model calculation of agricultural irrigation water consumption in multi-source irrigation area of South China.
