Study On Ecological Restoration And Landscape Design Of Abandoned Areas Of Limestone Mine

Since the 21 st century,with the improvement of people's awareness of resources and environmental protection,the reconstruction and reuse of abandoned mine land has became an important way to the sustainable use of land resources and it also is a vital part of sustainable urban development.The research on ecological restoration and landscape design of abandoned mine land has been paid more attention by experts and scholars from all walks of life.This paper sums up the research and development of the abandoned land of limestone mines at home and abroad,compares the present situation of our country,and puts forward the existing problems.The related theories of limestone mines abandoned land,ecological restoration and landscape design are combed out,and the application mode of ecological restoration and landscape design in the reconstruction of limestone mine abandoned land and the relationship between them are summarized.The design principles of limestone mine abandoned land are put forward in four aspects of art and sustainable development: conforming to nature,simulating nature,harmonious symbiosis,respecting the site,taking measures according to local conditions,considering the development of the times,creating "dynamic" landscape;Based on the combination of art and function,and in view of the characteristics of limestone mine wasteland,three key reconstruction elements were abstracted as specific landscape reconstruction methods: water storage,height difference treatment and plant design.Finally,combined with the above theoretical research and case analysis,the project practice of ecological restoration and landscape design of limestone mining area in Beshu Mountain Geopark in Delingha City,Qinghai Province is carried out.Through deep analysis of the concrete situation of the mining wasteland in the cypress mountain,the paper analyzes the geographical environment,regional cultural background and ecological factors of the mining area.In view of the mining degree of different mining sites,the mining area with excellent geographical position and obvious transformation effect is built as the key building,the site characteristic is increased,and the local folk culture of the Delhi is built up,so as to complete the reconstruction of the mining wasteland of the cypress mountain.Through the research on the ecological restoration and landscape design of the limestone mine wasteland and the landscape design practice of the cypress mountain mine wasteland,the paper provides some reference value for the reconstruction of the limestone mine wasteland.
