Research On The Key Factors Affecting The Benefits Of Mine Vegetation Restoration Projects

At present,the issue of vegetation restoration in mining areas has been increasingly concerned by the industry.Driven by the shortage of mining resources and the serious destruction of surface vegetation,the awareness of sustainable development of enterprises has gradually improved.At the same time,because of the strict requirements of environmental protection,engineering gradually develop of vegetation and the biodiversity and obtained a certain result,but the existing vegetation restoration project is not enough to realize the vegetation restoration and land reclamation of mining area has suffered from serious damage,vegetation restoration,soil and water conservation,biodiversity restoration and protection is imminent.Based on the predecessors' research experience and personal work from actual situation adaptability,economic value,ecological performance,four aspects of land suitability analysis the influence factors of vegetation restoration project benefit,build the Baoshan Long Ling Meng waxy mine vegetation restoration projects implementation efficiency index system of influencing factors,and using the Delphi method,the DEMATEL(decision test and influencing factors of laboratory)and RAHP(rough analytic hierarchy process)to the index system of selection and weight calculation,and by combining the weight index of sorting,ultimately determine the causal relationship between index analysis results quarry vegetation recovery efficiency of key influencing factors.Based on the comparative analysis of the situation before and after the implementation of the vegetation restoration project and the analysis results of the key influencing factors,Suggestions and countermeasures for improvement were put forward based on the successful experience of the project implementation,which provided an important reference for the design and implementation of other similar projects.
