| 摘 要： | 我国灌区妈水的利用率低，水浪费严重，这是农业节水主要潜力之所在。灌区应以开发利用浅层地下水为基础，引地表水作补充，采取井渠结合地表水地下水联合运用的灌溉方式，合理调控利用当地水资源。在靠井灌溉没有渠灌水源的地区，要拦蓄降雨径流及汛后河水回补地下源。在有条件开发地下水的河水灌区，要井渠并用，优化调度水资源。在灌溉管理上，要按农业用水量控制灌溉水量。建议按流域和灌区工发利用和管理水资源，在河水灌区积极

| Abstract: | Great potential lies in improvement of irrigation efficiency in China because of low irrigation efficiency at the time. Irrigation districts should adopt the combination of well and canal irrigation, taking the exploitation and utilization of shallow groundwater as the basis and diverting surface water as the supplement. The irrigation water consumption should be regulated according to the agricultural water demand. It is recommended to develop, utilize and manage water resources according to catchment and irrigation district. |
