Abstract

The invention discloses an ecological restoration method for engineering side slope treatment in alpine and high-altitude areas, and belongs to the field of ecological restoration engineering. Construction is carried out on surfaces of an exposed side slope by using a special engineering material; the special engineering material consists of a temperature regulation and control layer, a cold-resistant and drought-resistant matrix layer, a root-promotion soil moisture-preservation matrix layer and a slope surface improvement matrix layer. The slope surface improvement matrix layer is laid at the bottom of a matrix material; the root-promotion soil moisture-preservation matrix layer is arranged on the slope surface improvement matrix layer; the cold-resistant and drought-resistant matrix layer is arranged on the root-promotion soil moisture-preservation matrix layer; and the temperature regulation and control layer is arranged on the cold-resistant and drought-resistant matrix layer. According to the invention, construction soil, various solid wastes, natural mineral slag, microbial agents and a macromolecular modifier and the like are used as raw materials, and the functional designof different matrix layers is carried out, so that the ecological restoration method is suitable for severe environment conditions with cold climate, high ultraviolet radiation intensity, large temperature difference of day and night, strong temperature change and severe drought stress in alpine and high-altitude areas, and the ecological restoration effect of engineering side slope treatment inalpine and high-altitude areas is effectively improved.

Description

technical field [0001] The invention belongs to ecological restoration engineering, in particular to an ecological restoration method used in high-cold and high-altitude regions. Background technique [0002] The balance between engineering construction and environmental protection is a major issue of sustainable development and a requirement for building a resource-saving and environment-friendly harmonious society. The exposed slope is one of the geological environments formed in various major construction projects, which can not only cause geological disasters such as soil erosion and mountain collapse, but also produce ecological problems such as ecosystem fragmentation, ecological balance imbalance, and biodiversity reduction. It is urgent to carry out ecological reconstruction through engineering means and biological measures, restore biodiversity, and establish a stable, functional and self-sustaining ecosystem. [0003] When carrying out engineering construction in ...
