中文摘要:露天矿硬岩边坡的生态修复工作,因为缺少植物生长所必须的水土生境及与岩面牢固攀附的力学条件,所以历来便是矿山生态修复工作中较为棘手的技术难题。针对这一技术难题,国内外学者相继开展了大量的研究与实践工作,取得了一系列成果进展。本文综述了目前国内露天矿山硬岩边坡及高陡立面生态修复工程常用的复绿技术及其适用条件,包括以工程修复为主导的复绿技术和以生态修复为主导的复绿技术两大类,共十一种常用方法。同时指出这些方法在应用时常出现的三类问题,并提出了适合西北地区不同气候与边坡特征组合区域的几种联合修复模式。旨在为露天矿山硬质边坡及高陡立面的复绿工程提供技术参考。同时,对其他类型矿山开采区的边坡绿化以及恢复治理工作也具有一定借鉴意义。

Situation and existing problems of vegetation restoration technology of hard rock slope in open - pit mining area
Abstract:Because of the lack of water and soil habitat necessary for plant growth and the mechanical conditions that are firmly attached to the rock surface, vegetation restoration of hard rock slope in open - pit mining area is one of the more difficult technical problem. For this technical problem, domestic and foreign scholars have carried out a large number of related research and practice, and they have made a series of achievements and progress. This paper reviews the current vegetation restoration technologies and their applicable conditions for hard rock slope and high-elevation surface. Including the restoration technology of engineering-oriented and ecological restoration technology, a total of eleven commonly used methods. At the same time it pointed out three major categories of problems in the application of these methods. Several joint repair models are proposed, which are suitable for different combinations of climate and slope characteristics in northwest region. The purpose is to provide a reference for the construction and research work of the vegetation restoration. At the same time, there is also great significance to the slope greening and management of other types of mining areas.
