Hill collapsing and garden making water and soil conservation method

Abstract

The invention discloses a hill collapsing and garden making water and soil conservation method. The method includes steps of firstly, constructing a collapsed slope formed after hill collapsing into horizontal steps by a soil shifter; secondly, constructing ridging slopes with gentle gradients on the outer sides of the steps and manually punning the ridging slopes; thirdly, constructing high ridges on the edges of the horizontal steps on the inner sides of the ridging slopes; and fourthly, planting economic plants in the horizontal steps and finishing a hill collapsing comprehensive treatment process. The method effectively eliminates and reduces hill collapse phenomena caused by gravitational erosion, overcomes the shortcoming that a traditional hill collapsing slope is exposed, is obvious in water and soil conservation effect and abundant in hill collapsing slope landscape ecology, promotes development of hill collapsing ecological economy, has the advantages of high practicality, simplicity and obvious environmental protection effect, and is particularly suitable to be popularized and used in hill collapsing comprehensive treatment processes of vast red earth hilly areas.

Description

technical field [0001] The invention relates to a method for comprehensive treatment of collapsed hills, in particular to a method for water and soil conservation by utilizing collapsed hills for land reclamation. Background technique [0002] Collapsing hillside refers to the erosion phenomenon of hillside soil or rock weathering crust decomposing, collapsing and accumulating under the action of water force and gravity. It is a special form of gully erosion and mostly occurs in tropical and subtropical regions in southern my country. The harm caused by the collapse of hillock erosion is manifested in: destroying land resources, destroying basic farmland and other facilities, exacerbating natural disasters of flood, drought, and mudslides, deteriorating the local living environment, threatening the safety of people's lives and property, and causing serious ecological imbalance. According to incomplete statistics, since the founding of the People's Republic of China, the disa...

Problems solved by technology

In order to reduce the damage of gravity erosion and improve the surface landscape, scientists have carried out a series of research work, such as: building drainage channels on the upper slope of the collapsed hill to prevent the formation of confluence on the upper slope to scour the collapsed slope; drilling on the exposed slope of the collapsed hill Although afforestation, planting grass, and reducing soil erosion on the slope have all played a certain role in preventing and reducing soil erosion, all methods have not essentially slowed down the gravity erosion activity caused by the steep slope of the collapsing hillock. The phenomenon of slope collapse has not been fundamentally cured. At the same time, due to the hazards of drought in the dry season and landslides in the rainy season, it is still difficult to plant trees and grass on the slope of the collapse, and the unhealthy landscape of the exposed slope of the slope has not been significantly changed.
