Study On Landscape Planning And Design Of Mine Wasteland

At the beginning of the twentieth century,there were nearly one thousand abandoned land of various mines in Datong,Shanxi Province,which had ecological problems such as land collapse,environmental pollution and social problems of industrial stagnation.Subsequently,the state carried out vigorous remediation to rejuvenate the abandoned mine sites.Based on the literature review and theoretical interpretation of habitat environment science,sustainable development,landscape ecology and restoration ecology,this thesis refines the landscape design method of mine abandoned land through the study of mine abandoned land suitability evaluation method and the analysis of excellent design cases of mine abandoned land at home and abroad,such as Shanghai Chenshan mine garden and Biville quarry in France.And the empirical research and design practice are carried out by taking the abandoned land of Jinhua Palace Mine in Datong City as an example.The main conclusions of the thesis are as follows:1.The types of mine waste land are divided into coal mine waste land,metal mine waste land and non-metal mine waste land according to the difference of minerals.According to the characteristics of different types of landscapes,they are divided into occupation type,collapse type,and excavation type.2.The evaluation factors for the suitability of the mine abandoned land landscape are: surface slope,soil thickness,degree of damage,and landscape resource value;the scores obtained from the evaluation units corresponding to Cultural environment landscape,natural ecological landscape,and spatial activity landscape are obtained,and the scores obtained are >90,>95,>80 as the most suitable,80～90,80～95,70～80 as suitable,70～80,65～80,60～70 as less suitable,<70,<65,<60 are unsuitable.The above four levels are used for general analysis and judgment.3.The landscape design method of mine abandoned land includes ecological restoration of mine abandoned land,revival of regional culture of mine abandoned land and spatial experience design of mine abandoned land.The ecological restoration is based on biological restoration,soil reconstruction and landscape reconstruction;the revival of regional culture is carried out from four aspects,namely,preservation and extraction of regional culture,enhancement of regional culture,placement of regional culture and highlighting of regional culture;the spatial experience design is based on spatial structure design,spatial form design,spatial function organization design and spatial landscape design,etc.
