摘　　要：通南高沙土区部分已建管道灌区因一次性投资成本太大及单位面积年耗电费用过高,影响了该项技术的推广应用。为解决管道灌溉发展中的技术难题,根据通南高沙土区特点,分别就3种不同面积的典型灌区进行管灌系统设计。以典型灌区装置效率、管网工程单位面积投资、单位面积年耗电费用为控制措施,提出管道灌区单机单泵适宜控制面积,该成果可为通南高沙土地区发展管道灌溉提供技术支撑。Due to the large one-time investment cost and the high annual power consumption per unit area in some established pipeline irrigation areas in the high sandy soil area of south Nantong City,the popularization and application of this technology were affected.In order to solve the technical problems in the development of pipeline irrigation,according to the characteristics of high sandy soil area in south Nantong City,the design of pipeline irrigation system in three typical irrigation areas with different areas was carried out.Taking installation efficiency of typical irrigation area,unit area investment of pipeline network engineering and annual power consumption per unit area as control measures,suitable control area of single machine and single pump in pipeline irrigation area was proposed,which could provide technical support for the development of pipeline irrigation in the high sandy soil area of south Nantong City.
