【摘要】：我國西部半干旱礦區(qū)生態(tài)受到采煤與氣候的雙重脅迫,區(qū)域生態(tài)環(huán)境脆弱。掌握區(qū)域生態(tài)系統(tǒng)自然修復(fù)規(guī)律,可為半干旱礦區(qū)生態(tài)恢復(fù)與重建提供基礎(chǔ)理論參考。基于系統(tǒng)視角,分析了我國西部礦區(qū)煤炭地下開采對(duì)地貌、水文、土壤和植被等生態(tài)環(huán)境要素影響的研究進(jìn)展。分析指出,已有研究尚存在以下不足:研究尺度單一、各生態(tài)子系統(tǒng)間互饋關(guān)系不清、采礦對(duì)生態(tài)的擾動(dòng)機(jī)理不明、生態(tài)修復(fù)標(biāo)準(zhǔn)與評(píng)價(jià)體系不完善。今后應(yīng)從多尺度(特別是微觀尺度)定量研究西部礦區(qū)采煤對(duì)生態(tài)系統(tǒng)的損傷機(jī)理,構(gòu)建礦區(qū)生態(tài)系統(tǒng)自修復(fù)評(píng)價(jià)指標(biāo)體系并提出可量化的自修復(fù)標(biāo)準(zhǔn)。
[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.
