Embodiment 1

[0041] Such as figure 1 As shown, a kind of silt-hanging ecological bag provided by the present invention in the river bank water and land crisscross zone is specifically illustrated, comprising the ecological bag body 1 of the three-layer structure of the geotextile, the vegetation seed layer and the fiber protection film, and the two parts of the ecological bag body 1 The end and the center are provided with fixed connection buckles 2, and the ecological bag body 1 is U-shaped. The ecological bag body is made of 1 polypropylene man-made fiber. It has the key characteristics of water and soil conservation such as filtration, water permeability and soil impermeability, UV resistance, aging resistance, acid and alkali resistance, and plant friendliness. Eco bags usually have a lifespan of 120 years. The ecological bag body 1 has the following advantages: good moisture resistance, since the raw material of the ecological bag body 1 does not absorb moisture, the bag will not be...

Embodiment 2

[0043] Such as figure 2 As shown, an improvement is made on the basis of Example 1. The ecological bag body 1 is U-shaped, and the bottom 5 of the U-shaped is provided with an outwardly extending water diversion flange 7, and the water diversion flange 7 The central position of both sides is provided with arc-shaped indentation 8, and other structures are the same as in embodiment 1.

Embodiment 3

[0045] Improved on the basis of Example 2, such as image 3 As shown, a water distribution pipe 9 is provided on both sides of the water distribution flange 7, and the water distribution pipe 9 includes a bell-shaped water inlet 6 and a water outlet 3, and a water inlet 6 and a water outlet 3 are provided between the water inlet 6 and the water outlet 3. There is a bottleneck 4 that gradually shrinks inward, and other structures are the same as in Embodiment 2.

[0046] The invention provides an ecological restoration method using silt ecological bags hanging on the river bank water-land staggered zone, the ecological restoration method includes the treatment method of the high-water level water-land staggered zone and the treatment method of the constant water level water-land staggered zone, and the high-water level water-land staggered zone The governance method of the belt includes the following steps:

[0047] Step 1) From March to April every year, on the ground of the hi...

Abstract

The invention relates to the technical field of riparian vegetation restoration and greening, in particular to an ecological restoration method for performing warping on ecological bags in a riparianwater and land ecotone by using the ecological bags. According to the ecological restoration method, the ecological bags have effects of blocking and scour prevention, can protect plants to survive inthe rainy season under the situation of water impact, and achieve the effect of ecological restoration; the ecological bags can also intercept silts brought by the partial water flow to achieve the effect of soil and water conservation; the ecological bags and the planted plants can play a warping role, thereby promoting natural restoration and growth of vegetations; the plants absorb many harmful elements in a water body in the flood season, thereby eliminating pollution, purifying the water quality, improving the quality of the water body, and restoring the ecological function of the waterbody; after the plants grow up, the water and land ecotone can also have good ornamental value in the dry season. The ecological restoration method has the advantages that the survival rate and preservation rate of vegetation planting in the water and land ecotone can be increased, and the method provided for the vegetation restoration of the water and land ecotone is simple and convenient, can beimplemented in a large area, and is low in cost.

Description

technical field [0001] The invention relates to the technical field of river bank vegetation restoration and greening, in particular to an ecological restoration method for hanging silt ecological bags on the river bank water and land crisscross zone and utilizing the ecological bags. Background technique [0002] In the prior art, the ecotone of water and land refers to the two sides of the junction of river water and land until the influence of river water disappears. With the construction of large-scale water conservancy projects, more and more people pay attention to the ecotone due to its own characteristics. The Lijiang River is a natural water-land ecotone, which is an area where seasonal changes in water level cause the land on the shore of the water body to be submerged and exposed in a corresponding rhythm. Generally, it is submerged in water during the wet season, and leaves the water to form land in the dry season. Due to the damage to the ecological environment...
