Land Suitability Evaluation And Cost-effectiveness Analysis Of Reclamation Of Silica Sand Mine

In this paper, an example of silica Wanglong sand mine in Zhangwu, the research work for mine land reclamation plan, focusing a problem of land suitability evaluation of cost-benefit analysis on mine reclamation. Based on the large number of documents at home and abroad, combined with the actual situation in Zhangwu county, which was constructed index system and grading standards of land suitability assessment in Wanglong silica sand mine. Using entropy method and fuzzy comprehensive evaluation method for evaluating land suitability assessment of Wanglong silica sand mine,determining re-use direction of land reclamation. Based on budget estimate of land reclamation projects, for cost-benefit analysis and financial analysis of the land reclamation project. The research results show that the land reclamation plan of dry land, woodland and pond water is a reasonable land use directions in Wanglong silica sand mine, the cost-benefit analysis was calculated the project's net income, present value and rate of return on investment, that analysis demonstrated that land reclamation project is feasible.
