Research On The Ecological Restoration And Ecological Services Of Abandoned Mine Land In Mountain Regions

The environmental and economic problems of abandoned area of mining become increasingly serious in mountain regions, and it is necessary to restore ecology and restructure industry. Based on theoretical research, indicated that there is a certain relationship between ecological restoration and ecological services. Depthly studied the ecological restoration practice of Mentougou of the past few years, and tapped a variety of technical models of ecological restoration of the area, such as:mountain peak ecological picking garden, terraced hillside woods or orchard, coal waste pile landscape reconstruction, valley soil and water conservation, cultural theme park and mining museum, etc; Extended a series of innovative integrated technologies from the practice of ecological restoration in the demonstration areas, such as:hillside collapsed pit filling and vegetation restoration, terraced hillside collapsed orchard restoration, coal waste pile vegetation landscape reconstruction with no overburden soil, comprehensive utilization of mine water and water system building, construction of eco-living landscape with high-tech and development ecological military experience tourism; Those models and integrated technologies have very strong demonstration and reference for the ecological restoration of abandoned mine land in mountain regions. Depthly analysised the restored ecosystem from ecological economic point of view, indicated there have smooth flows of ecology and value, and it is a self-regulation and feedback independent healthy ecosystem; And according to the analysis of ecological services, and effect characterization and benefit, revealed the relationgship that ecological restoration is the driving force for ecosystem services achieving in mining wastelands, the optimal of ecosystem services is the orientation for ecological restoration, and human being are regulators of the process.
