Method for afforestation and slope protection on slope of terrace

Abstract

The invention discloses a method for afforestation and slope protection on the slope of a terrace. The method comprises the following steps of: building a terrace ridge slope with slower gradient on the outer side of the terrace, after manual tamping, building a high edge ridge on the outer edge of the terrace at the inner side of the ridge slope, and finally planting trees and grasses on the outer slope surface of the terrace ridge slope to finish the afforestation and slope protection process on the outer slope of the terrace. The method disclosed by the invention can be used for effectively eliminating and reducing the ridge collapse phenomenon caused by gravity erosion and overcoming the damage on original soil structure stability caused by spring freeze thawing expansion and rainy season dry and wet expansion, has a remarkable improvement effect, eliminates the bare state of the traditional terrace ridge slope by utilizing the characteristic that nutrient constituents in soil of the soil ridge slope are enriched and cultivating multiple drought-enduring forests and grasses and enriches the landscape ecological structure of the terrace ridge slope. The method disclosed by the invention has the advantages of strong practicability and simple method and is especially suitable for being popularized and used on terraces on arid regions or semi-arid regions.

Description

technical field [0001] The invention relates to a method for slope protection, in particular to a method for afforestation and slope protection on the outer slope of terraced fields. Background technique [0002] Reconstruction of sloping land into terraced fields is one of the main technologies for soil and water conservation in mountainous areas. Traditional terraced fields have steep ridges and are difficult to use. The gravity erosion caused by them is the main reason for the collapse of ridges and the destruction of terraced fields. In the 1990s, machine-repaired terraced fields were promoted on a large scale in the Loess Plateau of my country. Due to the fragmentation of the surface landscape and the increase in field width, the field width increased from 4-5m during manual construction to more than 14m, and the surface soil was directly pushed to the terraced fields. Ridges are rammed at the edges, and terraced fields are generally designed and constructed with a slope...

AI Technical Summary

Problems solved by technology

Although the research on planting trees and grasses on the ridges is very active, all ridge-protecting plants are planted on the edge of the terraced fields inside the ridges. This only slows down the gravity erosion of the ridges, and does not fundamentally solve the artificial ridge slope. After the increase, the problem of increased gravity erosion activity will be brought about, and the unfavorable landscape of exposed slopes will still remain unchanged.
