摘要
通过划分灌溉区监测典型村庄的灌溉面积、亩均灌水量、灌溉次数的典型点法和划分埋深分区测定不同埋深区电水转换系数的电水转换法,分别对试验区沧县2012年农业灌溉用水量进行了计算。分析了两种计量方法的优点与不足,在实际应用中如两种方法能有效结合,即农业灌溉地表水用水量的计量采用典型点法,地下水用水量的计量采用电水转化法,其计量结果更接近实际。
The typical point method is monitored irrigation area, average irrigation amount per mu and number of irrigation in typical village of different irrigation area. The electric water transformation method measured electric water transformation coefficient of different buried depth division. Using this two methods calculated the agricultural irrigation water consumption in 2012 of Cangxian experimental area, and analyzed the advantages and disadvantages of the two methods, if the typical point method measured surface water consumption, and electric water transformation method measured underground water consumption in the agricultural irrigation, the combination of two methods in practical application can make the measure result more closer to the actual.
