Embodiment Construction

[0015] The present invention can realize the above-mentioned beneficial effects in the geological environment treatment construction project of Jianshan abandoned mine in Danyang City, Jiangsu Province. The slope of mines in this area is mostly between 30° and 60°, and some steep slopes can reach more than 70°. The lithology of the mountain is mainly composed of limestone, and there are more mudstone in some parts, which is very easy to form landslides.

[0016] The hanging net is made of high-strength geogrid, usually a two-way double-layer geogrid, with a grid size of 7.4cm×7.4cm or 4cm×4cm, or No. 14 galvanized wire mesh, extending 6cm behind the top of the mountain or above the top of the slope -10cm, after fixing with anchors, backfill the soil, after the top of the slope is fixed, hang the net from top to bottom, the overlapping distance is not less than 10cm, bind it firmly with fire wire, and tie the net and anchor with fire wire Firm, keep a gap of about 3-4cm between...

Abstract

The invention belongs to the technical field of ecological engineering and particularly relates to a method of vegetation restoration and reconstruction of a bare rock slope in East China. the engineering materials such as active plant material and synthetic geonet are utilized, a plant-growing substrate (plant tool species seed, nutritional soil and binder) is uniformly mixed according to a certain proportion and injected on the rock slope according to the design thickness by a special injection device for the plant-growing substrate, an ecological environment which can ensure normal growth of the plant is created on the rock slope, the slope reinforcement and vegetation restoration are realized through the growth of the plant and other auxiliary functions, and the purpose of vegetation reconstruction of the bare rock slope is achieved. The method is applicable to the vegetation restoration and reconstruction of the bare rock slope in East China with respects to plant tool species and medium formulation and obtains obvious ecological benefits after several years of implementation and popularization.

Description

1. Technical field [0001] The invention belongs to the technical field of ecological engineering, and in particular relates to a method for restoring and rebuilding vegetation on exposed rocky slopes in East China. 2. Background technology [0002] With the rapid development of my country's industrial modernization, the ecological environment has been destroyed to a certain extent, the area of ​​bare land is increasing, and soil erosion is serious. There are many reasons for the formation of bare land: there are severe weather such as drought, severe cold, strong wind, and snowstorm; there are floods that erode the land and deposit sediment in another place, and sand that is blown up by strong winds and then piled up. There are landslides and landslides, etc., but the largest scale, the most ways, and the most profound are man-made activities. Under the tremendous pressure of population growth, the unreasonable development and utilization of natural resources has led to the...
