Embodiment Construction

[0045] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0046] see figure 1, The slope of the high and steep rock slope is greater than 45°. Because the slope is steep and vulnerable to rainwater erosion, the water flow is fast, and landslides are prone to occur, resulting in soil erosion. At the same time, there is a lack of soil, nutrients and water conditions for plant growth, and it is extremely difficult for slope plants to survive. . Using high and steep rock slopes to build bridle paths, fixing planting bags on the bridle paths, and preparing nutrient soil artificial restoration technology not only greatly improves the vigorous growth of plants, but also solves the problems of difficult vegetation restoration, single vegetation and weak natural regeneration ability on high and steep rock slopes. It enriches the methods of ecological restoration in engineering disturbance areas, is simple and easy to i...

Abstract

The invention provides a method for ecological restoration of artificial vegetations on a high and steep rock slope. The high and steep rock slope has the gradient of 45 degrees or above, plants growin an ecological bag filled with soil in a mode of anchoring the high-molecular polymer environment-friendly material ecological bag in the ecological restoration of the artificial vegetations, the plants are effectively fixed, and a technology of slope protection and environment restoration is achieved; and nutrient elements needed by plant growth are prepared in the ecological bag, plant seeds are directly mixed in formula soil or seedlings at an opening of the ecological bag are directly planted, the plants grow robustly, plant diversity is promoted, vegetation coverage is increased, vegetation communities are balanced, the habitat of the high and steep rock slope is well fused with the surrounding natural ecological environment, and the purpose of rapidly restoring the high and steep rock slope is achieved.

Description

technical field [0001] The invention belongs to the technical field of slope ecological restoration, and in particular relates to a method for artificial vegetation ecological restoration of high and steep rock slopes. Background technique [0002] With the rapid development of hydropower, transportation and other undertakings in recent decades, the sand and gravel materials required for the project are based on the principle of using nearby materials. After the main body of the project is completed, the original ecological system of the area has been greatly damaged. There are many quarry areas. A steep working surface above 45° is formed, and there is basically no vegetation growth. The restoration of high and steep rocky slope ecosystems, supplemented by artificial measures, increases the vegetation coverage of high and steep rocky slopes, so that the damaged ecosystem can gradually restore its original appearance or develop in a benign direction. However, the physical a...
