农业灌溉节水潜力估算研究在我国当前水资源匮乏的现状下理论意义与实践意义显著,基于当前已有的灌溉节水潜力计算理论,文章提出了农业灌区毛节水量与净节水量的区分与计算,并以灌区实际为例,分别估算了节水灌溉率提高30%和50%两种工况下的毛节水量与净节水量,结果表明,节水措施实施后灌区毛节水量增加所带来的节水潜力显著,但是立足于净节水量角度的节水潜力提升不明显,这也为下一步研究指明了方向。
Under the current situation of water scarcity in our country, the theoretical significance and practical significance are significant. Based on the current theory of calculating the potential of irrigation water saving, the paper puts forward the distinction between gross water saving and net water saving in agricultural irrigation districts Calculated and actual irrigation area as an example, respectively, estimated water saving irrigation rate increased by 30% and 50% under two conditions of gross and net water saving, the results show that the implementation of water saving measures to increase the gross water saving The potential for water saving is significant, but the improvement of water saving potential based on the net water saving is not obvious, which also points out the direction for further research.
