摘　　要：在气候变化和人类活动的双重影响下,造成北方水资源短缺日趋严重。做为北方地区重要的粮油生产基地的北方井渠结合灌区,也暴露出灌溉保证率偏低、田间节水体系不完善、水资源联合调度体制不健全、区域水资源平衡恶化加剧等现象,对灌区节水改造工程建设与管理水平进一步提升的不利影响日益显现。随着政府对农田水利建设投资逐步加大,客观上需要开展工程建设标准和综合节水配套措施的研究与探索,提出一套具有前瞻性的工程建设标准和配套节水措施。结合有关课题实践与研究成果,提出了一套适合于北方类似灌区节水改造工程建设标准和配套节水措施实施模式,对促进井渠结合灌区节水改造工程建设与运行管理具有重要的参考价值。Based on relevant practices and researches, by summarizing and analyzing relevant field test data, we proposed a main construction of implementation technical indicators of water saving in agronomy, engineering and management in the process of developing agricultural water saving in the well and canal irrigation district of northern China. Combined with the major problems in the provincial irrigation ending canal rebuilding project, we set up a set of project construction criteria and building modes for the similar northern irriga- tion districts, and explored and analyzed the improvement of field water distribution construction standards and the integrated water-saving measures, to promote the water-saving rebuilding work and benefit the project construction and management.
