以水稻为研究对象，利用涡动观测设备采集数据，采用Eddypro软件计算云南省楚雄州蜻蛉河灌区水稻各阶段的需水量并拟定该灌区水稻灌溉制度。结果表明：用涡动观测系统计算的水稻需水量与灌溉试验站试验资料接近，拟定的水稻灌溉定额与云南省《用水定额》标准十分接近。%Taking rice as the research object, using the data collected by the eddy observation equipment, water demand was calculated for Qingling River irrigation area of Chuxiong Prefecture in Yunnan Province with the aid of Eddypro software .And rice irrigation system was pro-posed for this irrigation area.Results indicate that water demand calculated by eddy observation equipment is close to the data of experiment station in this irrigation area, and the proposed irrigation quota is also very close to the water quota standard.
