摘　　要：低压管道输水灌溉适应性强,不受地形限制,施工安装方便,便于群众掌握,可解决零散地块灌溉问题,适合当前农业生产责任制形式,因此目前低压管道输水灌溉面积在节水灌溉面积中占的比例最大。所用管材又是该灌溉系统的重要组成部分,投资比重一般约占工程总投资的70%~80%,直接影响工程的造价。如何进行工程设计、降低投资成为关键。通过对不同的机井位置、地块形状情况下的田间工程费用比较,最终确定费用现值最小的机井位置、地块形状。Low pressure pipe irrigation has strong adaptability,which is not restricted by terrain and the installation is convenient,so it is easy to master by the masses,and the problem of scattered land irrigation can be solved.It is suitable for the current agricultural production responsibility system,so the low pressure pipeline irrigation area occupies the largest percentage in the water-saving irrigation area.The pipe is an important part of the irrigation system,whose proportion of investment generally accounts for about 70% ~ 80% of the total project investment,so it directly affects the project cost.To reduce project investment by optimized design has become the key issue.Through comparison of field engineering cost of different shaft position and block shape,the lowest-cost shaft position and block shape is finally determined.
