我国不少水库存在着泥沙淤积问题。水库泥沙淤积不但降低了水库的工程效益,当淤积向上游发展时,还会引起水库上游地区的自然和社会环境的变劣,这就是水库末端泥沙淤积引起的沙害,称之为水库末端的沙害,这是一种环境影响。本文就我国某些水库末端泥沙淤积引起的沙害作简略介绍和分析。 Many reservoirs in our country exist sediment deposition problems. Reservoir sedimentation not only reduces the engineering benefits of reservoirs, but also leads to the deterioration of the natural and social environment in the upper reaches of the reservoir when siltation is developed upstream. This is the sand damage caused by siltation at the end of the reservoir, which is called reservoir The end of the sand damage, this is an environmental impact. This paper gives a brief introduction and analysis of sand damage caused by sediment deposition in some reservoirs in our country.
