Open-pit mine ecological restoration method based on biodiversity

Abstract

The invention belongs to the field of ecology and biology, and discloses an open-pit mine ecological restoration method based on biodiversity. The method is based on ecological degradation mechanism analysis, ecological restoration target and range setting, ecological restoration scheme design based on biodiversity, ecological restoration engineering implementation, ecological monitoring and ecological restoration effect evaluation. The design of a mining area ecological restoration system is performed to provide a method support for ecological restoration of an open pit mine. Biodiversity and ecological characteristics of a mining area and surrounding areas are fully considered, a mine ecological restoration method system based on biodiversity is integrated, vegetation remodeling is performed by utilizing a regional vegetation succession rule, ecological restoration restriction factors are found out by utilizing ecological degradation mechanism analysis, a 'one-area-one-strategy 'measure is formulated, mining area ecological restoration is performed according to local conditions, self-succession of a mining area ecological system is finally achieved, and the method is simple and easy to implement and has popularization value.

Description

technical field [0001] The invention relates to a biological diversity-based open-pit mine ecological restoration method, which belongs to the field of ecological restoration. Background technique [0002] The open-pit development of mines has resulted in the destruction of surface vegetation, intensified water and soil erosion, and a sharp decline in biodiversity, and the ecological restoration work has seriously lagged behind. It is estimated that by 2020, China's open-pit coal mines will damage 0.22 hm of land 2 · million t -1 , followed by problems such as land degradation, soil erosion, and groundwater level drop, causing serious damage to the fragile grassland ecosystem and greatly threatening the regional environmental quality and ecological security. [0003] The goal of ecological restoration is not only to restore green, but also to reconstruct a self-sustaining and maintenance-free ecosystem through ecological restoration. The ecological restoration of mines in...
