Ecological restoration method of bare rock engineering wound-surface vegetation

Abstract

The invention relates to a method for ecologically restoring vegetation on the bare rock engineering wound surface, which belongs to the technical field of vegetation ecological restoration. A similarly natural mode is used to accelerate the restoration of the vegetation ecological environment and landscape. The method comprises the following steps: firstly carrying out the pretreatment on the bare rock engineering wound surface, and retaining the definite natural unevenness and fissure degree of the actual slope line (4) of the bare rock within the range from the low level control line (2) to the high level control line (3) of a designed slope line (1) under the preconditions of keeping a stable rock slope base and removing dangerous and floating stones; and by adhering to the concept ofartificial guidance and natural selection, adjusting measures to the local conditions according to the geological, geomorphic and climatic conditions and different target vegetations, and adopting different processes and slurries with different components to carry out the spray sowing on the rock slope. The method has low cost and high efficiency, facilitates the retention of soil and plant seed sources, and completes at one pass the vegetation restoration which needs years of accumulation and multiple superposition of the natural force. The vegetation ecological restoration is similar to thenature, but is far quicker than the nature. The prosperous period or declining period of a single species mutation can never appear. The method is particularly suitable for the large-area application, achieves the landscape and ecological effects in the near term, the medium term and the long term, and has practical and long term significance.

Description

technical field [0001] The invention belongs to the technical field of vegetation ecological restoration, and relates to a method for ecological restoration of exposed rock engineering wound vegetation. Background technique [0002] In the prior art, the ecological restoration of exposed rock engineering wounds mostly follows the combination of engineering technology and landscaping technology. Technical measures, after leveling, or constructing grooves, holes, or fixing boxes, bowls, or building brackets, anchor piles to hang nets, and then spraying base material soil on gentle slopes to form a considerable thickness of base material layer, generally more than 5cm thick The substrate layer contains soil, water, fertilizer, water-retaining agent and a large amount of adhesive materials, and then the surface layer containing plant seeds, soil, adhesive, fertilizer, water-retaining agent, water and other components is sprayed on the substrate layer , and carry out timely arti...

[0002] In the prior art, the ecological restoration of exposed rock engineering wounds mostly follows the combination of engineering technology and landscaping technology. Technical measures, after leveling, or constructing grooves, holes, or fixing boxes, bowls, or building brackets, anchor piles to hang nets, and then spraying base material soil on gentle slopes to form a considerable thickness of base material layer, generally more than 5cm thick The substrate layer contains soil, water, fertilizer, water-retaining agent and a large amount of adhesive materials, and then the surface layer containing plant seeds, soil, adhesive, fertilizer, water-retaining agent, water and other components is sprayed on the substrate layer , and carry out timely artificial maintenance, including covering the surface layer and establishing a sprinkler irrigation maintenance system, but too many artificial slope engineering leveling, stabilization auxiliary measures and plant growth auxiliary measures are not only costly, but also contain a large amount of water in the base material layer. Adhesive materials are not conducive to the development and growth of plant roots, so the ecological restoration state of vegetation, especially the long-term state, is very unsatisfactory, and it is very easy to have a single species mutation in the abundance or decline period, and it lacks a sense of convergence with the surrounding original environment, so it is not suitable for Especially for wide application on large areas
