灌溉水利用系数
efficiency of irrigation water
gUan灌溉gaishui liyong水利用系数XIShU(effieieney of irrigationwater)灌入田间的有效水量与渠首引进的水量之比,常以符号刀。表示,其计算公式如下: _琳,八八。刀臼二~二二;一入1、jU为 叽式中琳为进入田间的有效总水量;叽为从渠首引进的总水量。 灌溉水利用系数是评价灌溉渠系的工程状况和管理水平的一个重要指标,它既反映了灌区各级渠道的渗漏损失,义反映了在管理过程中无益的水量损失,如日灌夜排;因过量引水或不合理的配水所引起的渠尾泄水;渠道跑水;田面跑水和深层渗漏等。 为了提高灌溉水利用系数,主要的措施是进行渠道衬砌,减少渗漏;加强用水管理,实行计划用水,防止水量浪费和无益废泄。(谢安周)
