摘要
为进一步做好农田灌溉水有效利用系数测算分析工作,科学评价农田灌溉用水效率,本文以2019年温州市为例,共选择了26个样点灌区进行农田灌溉水有效利用系数计算,计算得出2019年温州市农田灌溉水有效利用系数,并与2018年系数进行了比较。结果表明,温州市2019年农田灌溉水有效利用系数为0.5948是科学合理的;通过提高灌区管理水平、加强高效节水和五小工程等农田水利设施建设,可提高温州市农田灌溉水有效利用系数。
In order to further calculate and analyze the effective utilization coefficient of farmland irrigation water and scientifically evaluate the efficiency of farmland irrigation water.In this paper,taking Wenzhou City in 2019 as an example,26 sampling irrigation districts were selected to calculate the effective utilization coefficient of farmland irrigation water,and the effective utilization coefficient of farmland irrigation water in Wenzhou City in 2019 was calculated and compared with that in 2018.The results show that the effective utilization coefficient of irrigation water in Wenzhou in 2019 is 0.5948,which is scientific and reasonable.The effective utilization coefficient of irrigation water in Wenzhou can be improved by improving the management level of irrigation districts and strengthening the construction of farmland water conservancy facilities such as efficient water saving and five small projects.
