摘要
根据灌溉水利用系数首尾测算法的有关概念和计算原理,测算了浙江省峡口灌区的灌溉水利用系数。计算结果表明该方法的测算成果比较符合峡口灌区的实际,并且具有概念清晰、计算简便、计算资料相对较容易获得等特点。该方法在灌区的具体运用,为灌区今后进行经常性灌溉用水效率评价提供了很好的思路。
According to the concept and calculation theory of front-rear method, the irrigation efficiency of Xiakou irrigation district, which is located in Zhejiang province of China, is evaluated in this paper. The evaluation result of the method is well accorded with the actuality of Xiakou irrigation district, and the method has several advantages including clear concept, convenient calculation process and easiness in obtaining computing data. Practical application of this method in irrigation district provides good reference for the future usual evaluation of irrigation efficiency in irrigation district.
