Research On Ecological Restoration And Landscape Reconstruction Of Quarry Wasteland Based On Mine Ecological Restoration

Recently,the rapid development of urbanization has led to a surge in demand for construction materials,and the number of quarries has been increasing year by year.The rapid growth in the number of quarries has to some extent met the needs of urban and rural construction and economic development,but the mining activities have caused great damage to the local landscape ecology.With the industrial restructuring and depletion of mineral resources,a large number of quarry abandoned sites have appeared across the country,which not only occupy land resources,but also cause serious pollution to the environment and bring great damage to the ecological environment.This paper systematically analyzes the research status of quarry abandoned sites at home and abroad based on mine restoration theory,analyzes and summarizes the relevant quarry abandoned sites transformation cases at home and abroad,researches the ecological restoration and landscape reconstruction methods of quarry abandoned sites,and takes the design of quarry abandoned sites in Sanli Township of Nanchang City as an example,improves the landscape value evaluation system of quarry abandoned sites,and forms a systematic and holistic quarry site protection It is important to improve the ecological environment of quarry abandoned sites and promote the sustainable development of the countryside,and further proves the feasibility of the restoration method.This paper is mainly divided into two parts: theoretical research and case design.The first part is a theoretical study.Firstly,we clarify the concepts of mine restoration,ecological restoration of quarry abandoned land and landscape reconstruction by reviewing the data,and analyze and summarize the actual cases of quarry abandoned land transformation at home and abroad.Then,according to the results of quarry abandoned land case analysis,the ecological restoration method of quarry abandoned land is summarized with the theory of mine ecological restoration,which is based on geological disaster prevention,terrain remodeling,soil reconstruction,water system construction and vegetation restoration;the landscape reconstruction method of quarry abandoned land such as functional transformation idea,spatial layout method and tour line system construction is proposed.The second part of the case design.Taking the landscape restoration design of Sanli Township Quarry in Nanchang City as an example,according to the site characteristics and the current situation of local ecological environment,the landscape restoration design method is applied to ecological restoration and landscape reconstruction.Firstly,the topography,soil,water system,vegetation and humanities of the site are analyzed,and Grasshopper superimposes four basic data of ecology,safety,ornamental and function,and uses hierarchical analysis to determine value weights and conducts landscape value evaluation,and proposes ecological restoration and landscape reconstruction strategy by combining the evaluation results;secondly,the site is ecologically restored through geological disaster prevention and control,terrain remodeling,soil reconstruction,water system construction,vegetation After that,the site is ecologically restored by means of geological disaster prevention and control,terrain reshaping,soil reconstruction,water system construction,vegetation restoration,etc.Then,the site is divided into functional partitions,a tour line system is established,and a landscape structure is designed to illustrate how to "activate" the site characteristics of rural quarry abandoned sites and reshape the spirit of place by means of ecological restoration and landscape reconstruction with practical cases.
