摘要
以陕西省观测资料为基础,运用首尾测算法,测算了陕西省2006—2013年的灌溉水利用系数,对陕西省灌溉水利用系数变化规律进行了初步分析,并对测算结果进行了分析与评价,结果表明陕西省灌溉水利用系数在逐年提高。
Based on the observation data of Shaanxi province, the objective of this research is to measure and calculate of irrigation water use efficiency in Shaanxi province and the related problems arising from this process. Research results showed that head-end method is suitable for Shaanxi irrigated area, irrigation water use efficiency was increased year by year.
