摘要
:在分析确定南方灌区灌溉水利用系数时 ,根据灌溉系统水量平衡原理 ,建立了田间水量平衡数学模型 ;利用灌区骨干水利工程和塘堰等水利设施供水量统计资料 ,并通过作物的灌溉定额 ,反推灌区渠系水利用系数和灌溉水利用系数 .
According to the water amount balance principle of irrigation system, a mathematical model of water amount balance in the field is established. The water efficiency of irrigation can be determined by calculating the crop irrigation quota on the theoretical plane and by making use of the water supply statistical data of main water conservancy projects and other water conservancy facilities.A new method for analyzing water efficiency of irrigation districts in \{China's\} southern region is suggested.
