Analysis of Disturbance Characteristics of Coal Mining on Ecological Environment and Ecological Restoration Technology
In order to improve the level of mine ecological restoration in China,aiming at the prob-lems of unclear disturbance mechanism of coal mining to ecological environment and imperfect ecological restoration technology,the disturbance characteristics of coal mining to ecological environment are ana-lyzed,and the existing ecological restoration technologies are sorted out.The disturbance characteristics of coal mining on the ecological environment include long disturbance period,wide disturbance range,com-plex disturbance objects(land,water resources,atmosphere,vegetation),and strong spatial and temporal heterogeneity.At present,the most important and effective ecological restoration technologies in coal mine areas include landform remodeling,soil reconstruction and vegetation reconstruction(species screening technology,species configuration technology and planting technology),which should be the focus of future research.In general,China is still faced with a large number of abandoned mines,complex types of ecologi-cal problems,and difficult ecological restoration.In the future,it is still necessary to further understand the disturbance characteristics,disturbance laws,damage conduction mechanisms and diffusion laws of coal mining on the ecological environment,so as to promote the research and development of new ecological res-toration technologies.
