Description

Construction method suitable for vegetation restoration of bare rock slope
Technical Field
The invention relates to a comprehensive treatment technology for mine ecological environment, in particular to a construction method suitable for revegetation of bare rock slopes.
Background
China is a mountainous country, the area of mountainous regions accounts for about 70% of the whole territorial area, and the expansion of urban geographic space is objectively restricted. In recent years, along with the rapid urbanization process of China, the paradox of man and earth is intensified, and a series of ecological environment problems are associated. The urban expansion in mountain areas inevitably involves the excavation of mountain bodies, so that exposed rock slopes are formed, the hidden danger of geological disasters such as collapse and landslide is caused, and the urban attractiveness is influenced. Ecological restoration of high and steep rocky slopes becomes a great problem of ecological protection. Along with the damage of the vegetation of the mountain landscape, the mountain side slope is leaner, and the natural landscape self-restoration is greatly influenced, so that the near-natural plant landscape restoration must be performed on the side slope manually in order to beautify the environment, protect the diversity of plants and maintain the stability of an ecological system.
The current slope landscape greening measures in China mainly comprise two measures, namely engineering protection measures and vegetation slope protection measures. The traditional engineering protection measures are as follows: the slope surface is reinforced, the surface protection wall is plastered, grouted, concrete is sprayed, net hanging and spray seeding are carried out, and the like, so that the slope surface has the advantages that water and soil loss can be rapidly prevented, and the instability and erosion effects in the initial stage of slope surface construction are better reduced; the side slope has the defects that strength efficacy is excessively pursued, the beautiful scenery degree of the side slope can be reduced, the ecological system is not favorably restored, and the concrete is weathered due to wind, sunlight and rain along with the time, so that the later maintenance is more troublesome. And the effect of the engineering protection measures on greening landscape vegetation of the mountain and improving soil is not good, the effect brought by adopting the vegetation slope protection measures is opposite to the effect, the effect is weak at the beginning, but along with the growth of plants, the effect of reducing the instability and the erosion of the slope surface is more and more obvious. The vegetation slope protection measures are liquid spray seeding, ditching and grass planting, three-dimensional net greening and the like, and the vegetation slope protection measures have the advantages that the diversity of plants can be restored, and the ecological environment is protected; the disadvantage is that the plant root system only grows on the surface of the side slope and can not grow in deep soil, so the effect of protecting the side slope soil is not good; the used plants have more herbaceous plants and poor landscape persistence; in addition, for the side slope with almost vertical destruction surface, if no engineering measures are taken, the plant growth substrate is difficult to be attached to the slope surface, and the plant can not grow.
The current patents and research achievements are complex and diverse, only aim at partial problems of mine side slope ecological restoration, are too single in purpose, incomplete in restoration effect, poor in ecological performance, low in restoration rate, short in effect and the like, and cannot systematically solve the mine side slope ecological problems.
