摘要
渠道输水效率、渠系输水效率、渠系配水效率和渠系水利用效率是渠系水资源利用效率的四个重要指标。造成渠系工程输水损失主要有渠道渗水及管理不当两大因素。重庆开县灌区实例分析表明,完善的渠道工程、搞好渠系维修护理、采用先进的设备以及科学严密的管理,可大大提高渠系水资源利用效率。
Channel water delivery efficiency,canal water delivery efficiency,canal water distribution efficiency and canal water utilization efficiency are four important indicators of canal water resource utilization efficiency.Factors result in the water delivery loss of canal engineering mainly include water seepage in channels and improper management.According to the instance analysis on the irrigation areas in Kai country,to improve channel engineering,to do well in maintenance and management on canal,to apply advanced equipment and manage scientifically and strictly would greatly improve the utilization efficiency of canal water resource.
