近几年来,由于各方面的原因,黄河下游河道淤积加重,排洪能力迅速降低,严重威胁堤防安全,1975年淮河出现特大暴雨,黄河下游防洪问题的严重性,更显得突出。为了防止洪水灾害,并利用水沙资源,在处理洪水的同时,透必须处理泥沙,使黄河下游河道淤积有所减缓,使水沙资源能为工农业生产服务。1969年治黄会议上确定了“拦、排、放”相结合的处理黄河洪水、泥沙的综合措施。利用黄河下游两岸背河盐碱沙荒及低产地
In recent years, due to various reasons, siltation of the lower reaches of the Yellow River increased siltation, flood control capacity rapidly reduced, a serious threat to dike safety, heavy rainfall in the Huaihe River in 1975, the seriousness of flood control in the lower reaches of the Yellow River, even more prominent. In order to prevent flood disasters and make use of water and sediment resources, we must handle sediment while dealing with the flood so that siltation in the lower reaches of the Yellow River will be slowed down so that water and sand resources can serve industrial and agricultural production. In 1969, the Yellow River Conference established a comprehensive measure of handling floods and sediments in the Yellow River combining “blocking, discharging and releasing”. Use of the lower reaches of the Yellow River back to the river salinization desert and low production areas
