A method and irrigation system suitable for ecological management of cliff sections in karst rocky mountainous areas

Abstract

The invention discloses a method and irrigation system suitable for ecological governance of cliff fracture surfaces in karst stony mountain areas. The method includes the steps of 1, manufacturing plant growing grooves, preparing pulling anchors, setting the installation positions according to the palisades tendency, placing the grooves in a staggered mode, and after grooves are formed in palisades and anchoring plates are installed on the palisades, constructing and fixing the plant growing grooves, wherein each plant growing groove comprises a water groove and a soil medium groove which areseparated from each other; 2, sequentially filling the plant growing grooves with supporting granules, separation nets and soil mediums blended with soil, fertilizer, water-retaining agents and seeds; 3, building an irrigation facility on the top of a cliff, and carrying out irrigation with the cooperation of the plant growing grooves. The whole devices involve a main irrigation water pipe, the pulling anchors, rock hillslopes, drainage water pipes, the anchoring plates, plants, outer walls, water groove baffles, a soil layer, the separation nets, the soil medium grooves, a water supply layer, the supporting granules, the water grooves, clapboards, segments of the main irrigation water pipe, the plant growing grooves and a water collecting gutter. According to the method and irrigation system suitable for the ecological governance of the cliff fracture surfaces in the karst stony mountain areas, the problem that ecological governance is difficult to achieve on fracture surfaces of stony mountains with high gradient is solved, the vegetation recovery effect can be achieved fast, management and maintenance are simple and economical, and the governance effect can be maintained for along time.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, especially the vegetation restoration technology under the conditions of large slopes and cliffs in the karst rocky mountain environment, and more specifically relates to a method for ecological management of cliff sections in karst rocky mountainous areas. Irrigation system for ecological management of cliff sections in karst rocky mountains. The present invention can be applied to the construction of corridor projects (roads, railways, water conservancy projects, oil and gas pipelines, etc.) in rocky mountainous areas, the construction of forest parks, the management of landslides, natural sections, and the recovery of mine landscapes and ecological environments for high-slope cliff sections. of vegetation restoration. Background technique [0002] Karst landform is a general term for the surface and underground forms formed by the dissolution of soluble rocks (mostly limestone)...

AI Technical Summary

Problems solved by technology

However, most of these methods are suitable for the restoration of low-to-medium slopes, and cannot be well applied to high-slope restoration areas such as cliff sections, especially cliff sections in rocky mountainous areas that lack soil, and are even more difficult to apply

The main reasons are: (1) The placement and fixation of restoration facilities for high-slope cliff sections has not been considered. When the slope is too steep, vegetation belts, foreign soil, grids, and lattice beams cannot be fixed on cliffs and cliffs by traditional methods; ( 2) The rocky mountain environment lacks soil, and climbing plants lack site conditions; (3) It is difficult to store water in the cliff section, and the water resources required for vegetation restoration are scarce; (4) It is difficult for traditional methods to hold soil, vegetation belts, and guest Soil and other soil resources are easy to lose, and cause soil erosion and water and fertilizer loss, resulting in environmental problems
