摘　　要：在高邮灌区节水改造作中统筹考虑灌区生态建设,并将其贯穿于灌区的规划、设计、施工与管理全过程。通过渠道的生态衬砌,集水期灌制度的构建,稻田与明沟湿地系统的联合以及灌区的活水畅水工程,提出一套适合南方灌区的生态节水减污、层层截污、活水净污的工程模式,产生了良好的节水减污效果,可为具有相似问题的南方丰水灌区节水防污改造提供支撑。In the construction practice of water-saving projects in Gaoyou Irrigation District ,ecological construction was considered . This idea was applied to the process of planning ,designing ,construction and management of the irrigation district .Ecological lining techniques were applied to irrigation channel lining .Scheduled irrigation management with centralized water supply was applied to water supply management .Field efficient water and nitrogen management ,and ecological ditch and pond system were together used for drainage and non-point pollution mitigation .The gate and the tunnel were constructed to improve the hydrodynamic conditions in channels ,ditches and rivers ,to enhance their water self-purification capacity .This engineering mode was tested effectively in impro‐ving water use efficiency and reducing non-point pollution ,and are expected to have a good function in irrigation districts with similar conditions in South China .

关 键 词：生态灌区 生态衬砌 节水工程 农田面源污染
