A method for ecological restoration of gully and plateau slopes in the gully area of ​​the Loess Plateau in eastern Longdong

Abstract

The present invention relates to a method for ecological restoration of gullies and plateau slopes in the gully area of ​​the Loess Plateau in the east of Longdong. Combining with topographic maps, the slope landform, erosion degree, and groundwater distribution are analyzed to match the corresponding slope types and slopes. Types include: (1) large slopes with large area cut and fill areas; (2) large slopes that are developing and surrounding conditions do not allow large area cut and fill works; (3) large slopes with sliding Small-scale landslides with low risk of collapse, good overall stability, and areas where there is a risk of wedge-shaped sliding in landslides and unstable slopes; (4) small slopes with tension cracks at the rear edge of the slope; (5) not allowed (6) There are buildings and structures that need to be protected. On the basis of maximally protecting the original topography, landform and ecological base of the Loess Plateau, the present invention can realize point-to-point precise restoration for gully areas of the Longdong Loess Plateau with different topography and topography.

Description

technical field [0001] The invention relates to the technical field of ecological environment restoration, in particular to a method for ecological restoration of gullies and grassland protection slopes in the gully area of ​​the Loess Plateau in eastern Longdong. Background technique [0002] Longdong area is located in the central part of my country's Loess Plateau, and is one of the typical regions for the development of loess landforms in my country. This area is characterized by alternating plateaus and gullies, vertical and horizontal gullies, sparse vegetation, and loose soil. Soil erosion is serious. With the disturbance of human activities such as urban expansion, infrastructure construction, and oil and coal resource development, water and soil erosion in gully areas has intensified, gully heads continue to extend, plateau surfaces shrink year by year, and natural disasters such as landslides, landslides, and collapses often occur. It is imperative to protect the g...

AI Technical Summary

Problems solved by technology

[0003] So far, the rigid management methods such as horse trails and terraced fields have been commonly used in the gully area of ​​the Loess Plateau in the east of Longdong to protect the plateau slope, which has a low degree of integration with the ecological environment and has destroyed the original landform and ecological base of the Loess Plateau.
