Willow-leaf embankment habitat restoration method based on temporary nutrient storage
The invention discloses a willow-leaf embankment habitat restoration method based on temporary nutrient storage. The method comprises the following steps that S1, the form of a current sand embankment is sequentially transformed to form a willow-leaf-shaped sand embankment; S2, gabion edging is conducted on the two sides of the willow-leaf-shaped sand embankment, willow branches are cut in gabions, nutrients carried by incoming water are retained, and a willow-leaf embankment habitat is formed; S3, multi-layer reinforcement is conducted on the embankment head upstream slope face of the willow-leaf embankment habitat, and temporary nutrient storage is conducted; and S4, water retention and salt accumulation are conducted through the method from the step S1 to the step S3, and willow-leaf embankment habitat restoration is completed. According to the willow-leaf embankment habitat restoration method, the current sand embankment is ecologically transformed on site, different forms of temporary nutrient storage areas are formed, the growth foundation of aquatic vegetation is enhanced, the quality of habitats for activities such as foraging, resting and enemy avoiding of aquatic animals is improved, and finally different forms of willow-leaf embankment habitats in river channels are formed.
本发明公开了一种基于养分暂储的柳叶堤栖息地生境恢复方法，包括以下步骤：S1：对现状沙堤依次进行形态改造，形成柳叶状沙堤；S2：在柳叶状沙堤的两侧进行石笼镶边，在石笼中扦插柳枝，并滞留来水挟带的养分，形成柳叶堤栖息地；S3：在柳叶堤栖息地的堤首迎水坡面进行多层加固，并进行养分暂储；S4：使用步骤S1至S3所述的方法进行潴水聚盐，完成柳叶堤栖息地生境恢复。本发明的柳叶堤栖息地生境恢复方法将现状沙堤就地生态改造，形成不同形式的养分暂储区，强化水生植被的生长基础，改善水生动物觅食、憩息和避敌等活动的栖息地质量，最终形成不同形态的河道内柳叶堤栖息地。
