Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of the prior art, such as incomplete effect, poor ecology, low repair rate, and short validity period, for the ecological restoration of slope vegetation in high-altitude areas, and provides a method for ecological restoration of slope vegetation, through the law of community succession. Slope vegetation treatment has achieved good ecology, high restoration rate, and stable succession direction after restoration, and it is not easy to rebound the treatment effect

Embodiment 1

[0036] The slope vegetation ecological restoration method includes the following steps:

[0037] Step 1. Carry out stepped slope cutting to form several platforms and slopes. On the platform, set a brick wall with the same width as the slope and facing the slope. The depth of the brick wall embedded in the ground is 500-800mm. The height is 800-1000mm, the thickness is 300-500mm, and the brick wall is plastered with C25 cement;

[0038] Step 2, filling the planting substrate between the brick wall and the slope facing it to form a planting groove, and planting shrubs and / or trees in the planting groove;

[0039] Step 3, mixing foreign soil, low-alkalinity cement, water-retaining agent, herb seeds and / or shrub seeds and water to make a concrete mixture, and spraying the concrete mixture on the slope; this implementation In an example, the weight ratio of each component is guest soil: low-alkalinity cement: water-retaining agent: herb seeds and / or shrub seeds: water=50:3:2:1:40...

Embodiment 2

[0044] The difference between this example and Example 1 is that due to the serious soil erosion of the slope, there are basically no microorganisms in the soil in some abandoned slopes, the land is very barren, and the plants planted by spraying will appear after a period of production. Withering phenomenon, by testing the soil of several such slopes, it is found that the soil fertility in these areas is very low, and the content of microorganisms and organic matter is relatively small. The following steps are followed:

[0045] Step A, opening several first grouting holes with a depth of 1.5m to 4m on the slope;

[0046] Step B. Mix organic matter, microorganisms, fertilizers, water-retaining agents, adhesives, soil and water into a sticky paste, and pour it into the first grouting hole through a grouting pump; in this embodiment, the weight ratio of each component is Organic matter: fertilizer: water retaining agent: binder:, soil: water = 1:12:8:6:54:41;

[0047] Step C,...

Embodiment 3

[0050] The difference between this embodiment and implementation 2 is that there are more heavy metal ions in some soils. The existence of heavy metal ions will not only affect the normal growth of plants, but also if heavy metal ions enter the domestic water, it will also affect the area. The health of residents is affected, so the degradation of heavy metal ions is also very important in the slope treatment process, so the present embodiment also includes the following steps:

[0051] Step D: Open several second grouting holes on the platform and part of the slope between the brick wall and the slope facing it, the depth of the second grouting holes is 2m-6m; Insert a thin tube made of biodegradable plastic into the grouting hole; several permeable holes are provided on the side wall of the thin tube; the degradable plastic is PBS in this embodiment;

[0052] Step E, select municipal sludge from a nearby city, add water with heterotrophic bacteria, stir and mix to form a sti...

Abstract

The invention discloses an ecological restoration method for slope vegetation. The method includes: step one, performing stepped slope cutting to form a plurality of platforms and slopes, and settingbrick walls as wide as the slopes and facing the slopes on the platforms, wherein the embedding depth of the brick walls is 500-800mm, the aboveground height is 800-1000mm, the thickness is 300-500mm,and the brick walls are provided with C25 cement plaster; step two, filling planting media between the brick walls and the opposite slopes to form planting grooves, and planting bushes and/or macrophanerophytes in the planting grooves; step three, mixing new soil, low-alkalinity cement, a water retaining agent and herbaceous seeds and/or bush seeds with water to obtain a concrete mixture, and spraying the concrete mixture to the slopes. By slope management according to the law of community succession, high ecological effects and high restoration rate in slope management are realized, the succession direction is stable after restoration, and less proneness to rebounding of management effects is realized.

Description

technical field [0001] The invention relates to an ecological system restoration method, in particular to a slope vegetation ecological restoration method. Background technique [0002] Vegetation has many benefits such as absorbing carbon dioxide, releasing oxygen, conserving water, protecting fresh water resources, protecting soil, and preventing soil erosion. Vegetation coverage will have a relatively important impact on the local ecological environment. As the country attaches great importance to environmental issues, it is vigorously developing afforestation, protecting cultivated land according to local conditions, linking increases and decreases, and ecological restoration of slope vegetation. [0003] Aiming at the ecological restoration of slope vegetation, various studies have been carried out at home and abroad, mainly focusing on slope protection, vegetation greening, soil matrix improvement, soil heavy metal pollution, etc., and proposed slope stability devices,...
