| 摘 要： | 从灌区水资源角度出发,提出灌区"资源型"真实节水量估算方法,分析计算了青铜峡灌区综合节水措施作用下的取水节水量和资源型真实节水量.计算得出,青铜峡灌区取水节水量为13.23亿m3,"资源型"真实节水量为6.54亿m3,相当于灌区取水节水量的49.43%.结果表明:在节水条件下,衡量青铜峡灌区的节水效果宜采用"资源型"真实节水量,因为只有"资源型"真实节水量才是有意义的.

| Abstract: | The condition are considered for water resources of irrigation area in this paper,we suggests that the calculating method ＂resources-type＂ real water saving quantity for the irrigation area,in the measuring for comprehensive water saving,analysing and calculating irrigation draft water saving quantity and resources-type real water saving quantity.Calculation results show the Qingtongxia irrigation area the irrigation draft water saving quantity is 1.323 billion m3,the resources-type real water saving quantity is 0.654 billion m3,the ＂resources-type＂ real water saving quantity is irrigation draft water saving quantity 49.43 %.Effect of water saving should adopt resources-type real water saving quantity,because only ＂resources-type＂ real water saving quantity is real water saving. |
