系统视角下中国西部煤炭开采生态损伤与自然修复研究综述
发布时间：2018-07-22 19:27
【摘要】：我国西部半干旱矿区生态受到采煤与气候的双重胁迫,区域生态环境脆弱。掌握区域生态系统自然修复规律,可为半干旱矿区生态恢复与重建提供基础理论参考。基于系统视角,分析了我国西部矿区煤炭地下开采对地貌、水文、土壤和植被等生态环境要素影响的研究进展。分析指出,已有研究尚存在以下不足:研究尺度单一、各生态子系统间互馈关系不清、采矿对生态的扰动机理不明、生态修复标准与评价体系不完善。今后应从多尺度(特别是微观尺度)定量研究西部矿区采煤对生态系统的损伤机理,构建矿区生态系统自修复评价指标体系并提出可量化的自修复标准。
[Abstract]:The ecological environment of semi-arid mining area in western China is fragile due to the dual stress of coal mining and climate. Mastering the natural restoration law of regional ecosystem can provide a basic theoretical reference for ecological restoration and reconstruction in semi-arid mining areas. Based on the systematic analysis of the effects of underground coal mining on geomorphology, hydrology, soil and vegetation in the west of China, this paper analyzes the progress of the research on the effects of underground coal mining on the ecological environment. It is pointed out that the existing research has the following shortcomings: the research scale is single, the mutual feed relationship among the ecological subsystems is not clear, the disturbance mechanism of mining to ecology is not clear, and the ecological restoration standard and evaluation system are not perfect. In the future, the damage mechanism of coal mining on ecosystem should be quantitatively studied from multi-scale (especially micro-scale), and the evaluation index system of mining ecosystem self-repair should be constructed and the quantifiable self-repair standard should be put forward.
