Vegetation configuration method for preventing water and soil loss of mine dump of dry-hot valley

Abstract

The invention discloses a vegetation configuration method for preventing the water and soil loss of a mine dump of a dry-hot valley. The method comprises the following steps: performing topsoil stripping on the dump; building an intercepting ditch, a drainage ditch and a water collecting tank on a platform of the dump; screening vegetation types, including shrubs, herbs and liana, suitable for growing in the mine dump of the dry-hot valley; performing targeted planting; after the vegetation of the mine dump is planted, enclosing the dump by using a wire mesh or a fence to prevent a slope surface from being destroyed by domestic animals. According to the principles of soil and water conservation and restoration ecology, vegetation species are reasonably combined by aiming at that the habitat of the mine dump of the dry-hot valley is severe and different slope positions have different soil erosion intensity and water conditions, so that a reliable technical path is provided for recovering the vegetation in a mining region as quickly as possible. Moreover, the vegetation configuration method for preventing the water and soil loss of the mine dump of the dry-hot valley has the characteristics of high operability and high comprehensive benefit.

Description

technical field [0001] The invention relates to a method for restoring vegetation in mine dumps, in particular to a method for constructing vegetation configuration patterns in dry-hot valley mine dumps, which is used to prevent and control water and soil loss in mine dumps. Background technique [0002] Dry-hot valley is a general term for valley belt areas with two basic properties of dry and hot. It is a common natural landscape in geography and is mainly distributed in the Minjiang River, Dadu River, Yalong River, Jinsha River and Nujiang River in southwest my country. , Lancang River, North-South Panjiang and other river valley slopes. The hot and dry valley region is rich in light and heat resources, hot and rainy, serious water and soil erosion, very fragile ecology, sparse vegetation, and low forest coverage. [0003] The hot and dry valley not only has good heat and light conditions, but also has rich mineral resources in the region. Taking Panzhihua as an example,...

Problems solved by technology

[0006] Compared with other areas, mine dumps in hot and dry valleys, due to the extremely dry and hot climate, the soil is very poor, and it is difficult to directly apply the traditional vegetation management model to achieve results

At present, there are few reports on vegetation control measures for mine dumps in dry-hot valleys, and no systematic research has been carried out on species selection and configuration model optimization for vegetation restoration in waste dumps.
