墨西哥90%,日本68%,前苏联50%,美国44%,波兰16%,德国10%,英国4%。据1993年资料,中国农业用水占总用水量的74.3%,中国农业用水在总用水中所占比重很大,而其 喷灌 (河北省玉田县供祸)中绝大部分又用于农田灌溉。因此,节约农业用水,特别是农田灌溉用水,对于中国这样一个水资源相当贫乏的国家来说,有着重要意义。节约农业与农田灌溉用水的途径有:①调整农业结构和作物布局,使水土资源优化利用,达到节水、增产、增收目的;②广辟水源,并尽可能做到一水多用,充分利用;③采用渠道防渗、管(带)输水等措施,减少输水损失(参见彩图插页第33页);④平整土地,改进传统的地面灌水技术;推行小畦灌溉、细流沟灌,避免串灌串排的淹灌;⑤积极推广喷灌、滴灌、微喷灌、渗灌等先进、节水灌溉技术和相应的制度;⑥采用蓄水保墒耕作、田面覆盖保水等节水农业措施。 (窦以松)nongye yongshui农业用水(agncultu司water use)农、林、牧、副、渔业等部门和乡镇、农场企事业单位以及农村居民生产与生活用水的总称。1975年,全世界工农业和城市生活用水量约3万亿立隆 水中养鱼方米,其中农业用水为2.1万亿立方米,占70%。目前,世界农业用水每年以2.3%的速度递增。各国农业用水占总用水量的比重,随地区气候条件和工业化程度不同而异:印度叩%,
