宁夏惠农渠灌域供水现状及节水潜力分析

An Analysis of Current Situation of Water Supply in Ningxia Huinong Canal Irrigation Area and Water-saving Potential

宁夏惠农渠灌域由于渠道砌护率低、输水损失大,致使渠道水利用系数偏低。通过对惠农渠现状工程运行情况及灌溉用水结构、用水量等的调查,从多方面分析灌域渠道砌护后的节水潜力,并对灌溉用水提出建议,为灌域的用水管理提供技术依据。

Due to a low lining rate and a large water conveyance loss in the Ningxia Huinong canal irrigation area, the canal＆#39;s water use coefficient is low. Based on an investigation on the present situation of the canal＆#39;s operation, irrigation water use structure and water consumption, the water-saving potential after the lining of the canals in the irrigation area are analyzed from various aspects. Some suggestions about the irrigation water use are put forward to provide a technological support for the water use management in the irrigation area.
