Research progress and prospect of vegetation restoration measures in coal mine dump
With the improvement of environmental protection awareness,the vegetation restoration of coal mine dump has become an important part of mine ecological management.The main research progress of vegeta-tion restoration in coal mine dump in recent years was reviewed in this paper,including soil improvement,selec-tion of suitable plant species,ecological engineering technology and other measures,and the future research di-rection was prospected.The important role of soil improvement in vegetation restoration was introduced,including improving soil physical and chemical properties,increasing soil fertility and water retention ability.Then,the im-portance of selecting suitable plant species for vegetation restoration was expounded,especially selecting plant species with strong adaptability and ecological functions.In addition,some emerging ecological engineering tech-nologies,such as bioengineering and alternate planting of plants,which are of great significance to improve the efficiency and effect of vegetation restoration were also discussed.
