摘要
以海安市夏秋季农田灌溉情况为例,采用首尾测算分析法测算不同作物种类、不同灌溉条件的毛灌溉用水量和净灌溉用水量,进而反映出海安市夏秋季农田灌溉水有效利用系数整体水平,为海安市农田水利工程建设和管理提供评价依据。
Taking the farmland irrigation in summer and autumn of Hai’an city as an example, the gross irrigation water consumption and net irrigation water consumption of different crops and irrigation conditions are calculated by the head tail calculation analysis method, which reflects the overall level of the effective utilization coefficient of farmland irrigation water in summer and autumn of Hai’an City, and provides the evaluation basis for the construction and management of farmland water conservancy projects in Hai’an city.
