Study On Planning And Design Of Landscape Reconstruction In Abandoned Mining Area

The impact of abandoned mining area covers many aspects such as the degradation of ecosystems,the decline of economic development and the aggravation of social problems.China is a major mining country.The negative impact of further exhaustion of mining resources will surely curb the sustainability of ecological,social and economic construction in more regions.As a means to effectively cope with this phenomenon,with the promotion of policies and governments at all levels,landscape planning and design has gradually become one of the important ways to reconstruct abandoned mining area in China.However,due to the late start of research and development in related fields,the current practice generally has the phenomena of quick success and immediate benefits,and emphasizes economy rather than ecology.The lag in the development of related systematic theories and insufficient protection of resources have also impeded the sustainable realization of mining waste land.At present,combing practical and feasible planning and design methods has become a key issue for recycling of mining wasteland in China.It has been a long time for the reconstruction of abandoned mining area with landscape planning and design as a means.Both domestic and foreign countries have carried out long-term related practice under conscious and unconscious conditions,and instructive theories are gradually integrated and developed in this process.On the basis of clarifying the concepts of abandoned mining area and landscape reconstruction,this thesis systematically sorts out the development process of the theoretical and practical development of abandoned area landscape reconstruction at home and abroad taking development timing as the clue,and proposes the abandoned mining area landscape reconstruction in different historical environments.The historical mission from a single consideration of landscape beautification to a complex overall planning of multiple benefits.Afterwards,through the literature analysis of relevant theories,combined with relevant excellent cases to conduct research and summary,completed the basic part of the thesis.The core part of the thesis can be divided into three parts,which are "Environmental Resource Evaluation","Planning Strategy Research" and "Empirical Research".Through sorting out the basic research and on-the-spot investigation of Chengde Shuangfengsi Iron Mine site,the thesis first summarizes the types of resources in the abandoned mining area that have remarkable significance in the two dimensions of recreational development and ecological restoration,and takes coordinated development and protection as the place to start,a "Mining Abandoned Land Development Suitability Evaluation System" was established to provide guidance for the spatial layout.In addition,in order to achieve sustainable and long-term operation of the landscape reconstruction of abandoned mining area,on the basis of identifying important resources and drawing on the specific practices of previous people,the planning and design of abandoned mining area landscape reconstruction was proposed guided by the implementation of planning and design.Strategies are discussed from three dimensions,namely " Space Layout "," Ecological Restoration ",and "Characteristic Creation",including the specific planning and design methods in 10 aspects.Finally,the thesis uses the Shuangfengsi Iron Mine Site Park as an empirical carrier to verify the planning and design path to ensure specific enforceability.Driven by the background of actively promoting the development of "green mines" in Chengde City,the thesis intervenes from the perspective of landscape architecture and takes Shuangfengsi Iron Mine Cultural Relics Park as a practical example,with a view to providing a path and reference for the related types of abandoned mining area landscape planning and design.
