堤防新上的土方,虽然经过夯实、碾压,但由于没有林草植物保护措施,在近年没有完全沉实的情况下,堤防的水土流失现象是比较严重的。降水和冰雪融化所产生的径流、通过面蚀把土运送到堤下,通过沟蚀把土冲推到堤外。为了减少和避免堤防的水土流失,一定要从防御出发,采取工程措施与生物措施相结合的战术,可 Although new earthwork on the embankment has been rammed and rolled, due to the absence of grass and plant protection measures, the phenomenon of soil and water loss in dikes is rather serious in the absence of complete solidification in recent years. Runoff from precipitation and melting of snow and ice will be transported to the embankment by surface erosion and will be pushed outside the embankment by gully erosion. In order to reduce and avoid the soil and water loss of embankments, we must proceed from the defense and adopt the tactics of combining engineering measures with biological measures.
