摘　　要：尊村引黄灌区是山西省一座大型多级提水灌溉工程。由于所引黄河水的泥沙含量较高,导致灌渠泥沙淤积问题十分严重,影响到了渠道的正常运行。为了掌握灌区渠道水沙分布规律,缓解渠道淤积问题,在尊村二干渠设立7个观测面开展泥沙含量与粒径级配观测和分析。研究结果可为灌区管理和节水减沙工作提供参考依据。Zuncun Irrigated Area of Yellow River Diversion Project is a large multistage project for irrigation in Shanxi Province. Because of the sediment concentration of the Yellow River is higher, the sedimentation problem of irrigation canal is ver}^ serious, affecting the normal op-eration of the canal. In order to grasp the irrigation canal of distribution regularity of water and sediment and ease the aggradation of canal, seven obsen？ation surfaces in Zuncun secondar}^ trunk ditch was set up to monitor water and sediment in this study. The study results can pro-vide a basis for irrigation district management and water-saving and sediment reduction.
