对三义寨引黄渠首闸引水渠道淤积造成的农业经济损失、地下水资源过度开发、水体污染严重等负面影响进行了分析,提出了渠首闸泥沙治理措施:①建设黄河滩区引黄沉沙供清工程;②引渠口设立鱼嘴或拦沙堰阻沙分沙;③渠系输沙减淤;④浑水灌溉、输沙入田。同时,对泥沙综合利用的前景、作用和发展方向进行了分析。

Comprehensive Treatment of the Yellow River Sanyizhai Sluice Gate Sediment

This paper analyzed on the negative effects,such as agricultural economic loss,excessive exploitation of groundwater resources,serious water pollution caused by the sediment depositing at the head of the Yellow River Sanyizhai sluice gate and puts forward control schemes: ①construct diversion project for sedimentation in the Yellow River flood plain;②build sand trap at the mouth of inlet channel to retain and divert sediment;③transport sendiment and reduce silt in canal system;④irrigate with muddy water and transport sediment into the fields.At the same time,the prospect,function and development direction of comprehensive utilization of sediment are analyzed too.
