豫东平原引黄灌溉,大量泥沙随浇灌退水进入下游河道,加上本地区的水土流失,造成下游河床的严重淤积,降低了河道的防洪、排涝能力。本文以涡惠河为例,对豫东引黄灌溉引起的河道淤积的原因进行分析,并提出了防治措施。 Irrigation in the Yellow River in the eastern part of the Yellow River led to a large amount of sediment to flow back into the lower reaches of the river with irrigation and water loss and soil erosion in the region, resulting in serious siltation of the downstream riverbed and reducing flood control and drainage capacity. In this paper, the case of Xuanghu River was used to analyze the reason of river siltation caused by the Yellow River Irrigation in the East of Henan Province, and the prevention measures were put forward.
