Problems solved by technology

Although the treatment speed is fast, the species richness and diversity in the sample plot are promoted, and the plant coverage effect is intuitive, but the soil and rock background in the target treatment area are not deeply considered, which is likely to cause vegetation degradation, low sustainability, and biological invasion.

Embodiment 1

[0061] Embodiment 1: Take the ecological restoration project of the rocky slope of the DG Hydropower Station in Tibet as an example for illustration.

[0062] 1. Project overview:

[0063] The project is located in the Tibet DG Hydropower Station, in the transition zone on the southeastern edge of the Qinghai-Tibet Plateau, and in the middle reaches of the main stream of the Yarlung Zangbo River. The topography features typical high mountains and river valleys in the study area. The regional climate belongs to the plateau temperate monsoon semi-humid climate zone, with little rainfall and drought in winter and abundant precipitation in summer. According to meteorological statistics, the local annual average temperature, precipitation, evaporation and relative humidity are 9.2°C, 540.5mm, 2084.1mm and 51% respectively, and the maximum permafrost depth over the years is about 19cm. The main soil types in the project area are grassland soil, aeolian soil, coarse bone soil, etc.,...

Embodiment 2

[0076] Example 2: Ecological Restoration Project for Construction Hardened Slope of DG Hydropower Station in Tibet:

[0077] 1. Project overview:

[0078] The project area of ​​this project is the same as the work area where the first embodiment is located. The selected construction hardened slope is a square area with a slope of about 35°, a length of about 41m, a slope height of about 12m, and a total area of ​​about 500m 2 . The project started on May 23, 2018 and was completed on August 29, 2018. Two years after the implementation of the ecological restoration project for the hardened slope of the Tibet DG Hydropower Station, nitrate nitrogen, available phosphorus, and available Potassium levels are low and the vegetation appears malnourished.

Embodiment 3

[0090] Example 3: Taking the ecological restoration project of the soil-rock mixed slope of the DG Hydropower Station in Tibet as an example:

[0091] 1. Project overview: The project area of ​​this project is the same as that of Embodiment 1. The selected earth-rock mixed slope is a square area with a slope of about 46°, a length of about 22m, a slope height of about 18m, and a total area of ​​about 400m 2 . The project started on May 23, 2018 and was completed on August 29, 2018. Two years after the implementation of the soil-rock mixed slope ecological restoration project of the DG Hydropower Station in Tibet, the vegetation on the slope surface died and fell from time to time during the drought and rainless period.

Abstract

The invention discloses a dynamic evaluation, regulation and control method for ecological restoration benefits of an engineering disturbance slope in a high mountain area. A dynamic evaluation system for the ecological restoration benefits of the engineering disturbance slope in the high mountain area is constructed; a reasonable regulation and control scheme is formulated according to the evaluation result; and regulation and control are implemented to solve the real-time problems in ecological restoration of the target slope. According to the evaluation system, a hierarchical structure model for slope ecological restoration evaluation is established, an optimal evaluation index weight and an index evaluation standard are formulated, and comprehensive evaluation is performed on slope ecological restoration benefits according to the evaluation index weight and the index evaluation standard. And through circular evaluation and regulation, optimization of a slope ecological system is achieved. According to the method, the difference and regional characteristics of the high mountain area are fully considered, a real-time quantitative and qualitative evaluation and scientific regulation and control scheme is provided for the ecological restoration benefits of the engineering disturbance slope in the high mountain area, and the scientific theory of the engineering disturbance slope vegetation restoration technology can be improved.

Description

technical field [0001] The invention relates to the field of slope ecological restoration, in particular to a dynamic evaluation and control method for ecological restoration benefits of engineering disturbance slopes in alpine areas. Background technique [0002] Southwest China, including Qinghai-Tibet Plateau, Yunnan-Guizhou Plateau and other high mountain areas, is rich in hydropower resources, creating favorable conditions for comprehensive development of hydropower projects. However, as a key ecologically fragile area, a large number of engineering disturbances will destroy the original slope ecosystem, such as soil erosion, vegetation degradation, water and soil conservation and stability decline. Unlike earthquake landslides, which can promote the evolution of slope topography as part of the self-regulation of mountains, engineering construction will leave permanent scars on slope ecosystems in alpine regions. Ecological restoration of engineering disturbed slopes i...
