Mining wasteland due to mining caused soil erosion , degradation of ecosystems , affecting the production of life and sustainable development of the regional economy of the surrounding residents . Mining wasteland site type is divided into the vegetation restoration construction work , an important measure to ensure the survival rate of the vegetation and improve green production levels . The first cloud iron ore Beijing within the construction of the largest , most representative of iron ore plant , select it as the study site by typical significance . Data collection and field sample survey , a more detailed investigation of the mine climate , altitude , topography , geomorphology, soil , vegetation recovery , mining wasteland by artificial disturbance of vegetation has been to restore divided into two class : interference bare slope and vegetation has been restored slope . The different composition of the surface material is divided into two major categories rocky slope , rock mixture slope , the mine tailings slope three cases . Its site factors , respectively, to determine the effects of vegetation restoration quadrat survey . Data using principal component analysis , regression analysis , combined with the judgment of the situation on the ground to identify each type of group opposition to have a decisive influence on the dominant factor , then the site type on factor hierarchical combination method or clustering method and named the dominant factor for each site type . Final slope, aspect , degree of weathering , soil thickness , recovery mode dominant factor of the first cloud iron ore waste to be divided into six types of group 25 site type . Site types for each bare land , according to local conditions , in accordance with the recent natural principle of integrated planning , recommending of reasonable ecological governance and vegetation restoration measures , in order to create a the Habitat harmonious social environment .
