中国北方露天煤矿区植被恢复研究进展

A review on vegetation restoration of opencast coal mine areas in northern China

煤炭开采破坏了土地原有的自然属性,进而导致一系列生态和环境问题,形成大量矿山废弃地。恢复受损的土壤和植被是矿山废弃地生态复垦的关键。本文在查阅国内外大量相关研究成果的基础上,就中国北方露天煤矿区生态复垦过程中植被恢复的研究现状及当前研究存在的问题进行了评述,并指出今后工作内容的重点是开展长期定位监测,加强煤矿废弃地土壤-植被系统的长期定位研究,为露天煤矿区的合理经营与管理提供科学依据。

Coal mining has destroyed the original natural attributes ot land, leading to a series ot ecological and environmental problems and forming a large number of abandoned mining lands. Restoring the damaged soil and vegetation is the key to the ecological reclamation of abandoned mining lands. Based on the relevant research results at home and abroad, we review the current research progress of vegetation restoration and existing problems in opencast coal mine areas in northern China. We then point out that long-term field monitoring and in situ research of soil-vegetation systems are the important part of the future research, aiming to provide a scientific basis for reasonable management of opencast coal mine areas.
