Species selection and configuration method for ecological restoration of damaged slopes in southwest mountainous area

Abstract

The invention relates to the technical field of ecological environment protection and ecological restoration, in particular to a species selection and configuration method for the ecological restoration of damaged slopes in a southwest mountainous area. The specific technical solution is as follows: the species selection and configuration method for the ecological restoration of the damaged slopescomprises the following steps: first analyzing the damage situation of the slopes in the southwest mountainous area, and dividing the slopes into different types according to the site conditions of the damaged slopes; then recording a species list of natural forests in undamaged areas around the different types of damaged slopes, and the slope vegetation which is naturally restored for many years; calculating important values of the species, and selecting a list of species suitable for different slope types; and then determining planting quantity and planting density of restored species according to the number of the species in the species list, and finally determining a species configuration solution of the ecological restoration of the slopes. The method solves the problems of single spray-seeding species, simple species planting model, low integration degree between restored slopes and surrounding natural forests, and the like in the existing ecological restoration of slopes.

Description

technical field [0001] The invention relates to the technical field of ecological environment protection and ecological restoration, in particular to a species selection and configuration method for ecological restoration of damaged slopes in southwest mountainous areas. Background technique [0002] With the development of highways, railways and other engineering construction and the occurrence of natural disasters, many exposed slopes have emerged in our country. These slopes not only affect the natural landscape and ecological environment, but also endanger the lives of local people. At present, the ecological restoration patents for these slopes mainly focus on the engineering devices for slope treatment and the construction methods to maintain their stability, such as the preparation method of grouting material, the embankment structure for soil consolidation, etc.; at the same time, there are some The invention focuses on the research and development of slope greening ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for species selection and configuration for ecological restoration of damaged slopes in southwest mountainous areas, specifically including species selection, planting and configuration schemes, to solve the problems existing in the ecological restoration of existing damaged slopes. The spraying species is single, the species planting mode is simple, and the integration of the restored slope with the surrounding natural forest is low.
