Example Embodiment

[0086] Example 1

[0087] As attached figure 1 As shown, a construction method for bank ecological slope protection includes the following steps:

[0088] ①Using the sand slope on the east side of the Xiyong River in Shenzhen as the experimental base, the slope protection area is determined. The slope protection area is determined to be the lower limit line of the slope protection at 0.75 meters above the elevation of the Yellow Sea. The slope protection area is extended to The top of the embankment.

[0089] ②Lay the planting bed, as attached Figure 2~4 As shown, in the slope protection area, use wooden stakes to fix a reed fence made of wheat straw or straw rope. The width of the reed fence is 1 meter, and the gap between adjacent reed poles is 15 mm; then the reed fence is drenched After penetration, cover a layer of mixed soil of sand and clay with a thickness of 2 cm to 3 cm and a mass ratio of 1: (2 to 4).

[0090] According to the time of local tide flooding, the number of fl...

Abstract

The invention belongs to the technical field of ecological restoration, and especially relates to a construction method of embankment ecological slope protection. Through the combination with embankment rising tide and the growth characteristics of plants, different plant communities can be constructed on sea sand dam slopes with different elevations according to tide conditions and plant growth characteristics so as to adapt different submergence depths, frequency and duration of submergence time of seawater; and through the combinations and matching of the plants, compatible, layered and stable plant communities can be constructed. Thus, ecological restoration targets of preventing wind, fixing sand and protecting embankment can be achieved, coastal saline alkali soil can be improved, and the effects of acting as embankment landscape can be realized; and the construction method has significant ecological significance.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a construction method for embankment ecological slope protection. Background technique [0002] In the southeastern coastal area of ​​my country, there are a large number of tidal rivers connected to the sea. Most of the embankments are formed by the accumulation of sea sand, and the coastal embankments are also formed by the accumulation of sea sand. Coastal sand embankments and chaochao river embankments are affected by perennial tide movement, wind and wave blowing, typhoon erosion, and man-made damage, resulting in the structure of most coastal embankments and coastal sand dams in my country being extremely unstable and seriously damaged. Gradually lost. Especially on both sides of the river that is connected to the sea, due to the ebb and flow of sea water and the artificial excavation of fish ponds, it is easier to form banks with sea sand on the ...
