摘  要:
稻田节水工程技术中,明渠输水、管道输水是目前比较主要的节水工程技术措施,较土渠输水速度快,防渗效果好,能够较有效地减少输水过程中的水量损失,提高水利用效率。通过选择杭嘉湖平原河网区典型水稻灌区,利用静水法和首尾法,分别针对灌区内明渠和暗管进行输水效率对比试验,基于试验成果,分析评价平原河网区不同节水工程技术对灌区输水效率的影响。

摘  要:
Open channel and subsurface pipe water conveyance are major water-saving engineering measures with the feature of fast and effective anti-seepage,which can be more effective in reducing water losses in the conveyance process and improving utilization of water.In this paper,conveyance efficiency comparison test on open channel and subsurface pipe is carried out,respectively,in typical rice irrigation area of Hangjiahu plain by using hydrostatic method and end-begin method.Based on the results,the impact of different water-saving engineering technology on conveyance efficiency in irrigation district are further analyzed and evaluated.
