高潜水位矿区塌陷土地复垦效益估算研究

摘要

The benefit of land reclamation in mining subsidence area with higher level of underground water is an important basis for investment decisions .Based on Qidong Mine reclamation project ,this study learns reclamation benefit evaluation literature ,thus establishes appropriate indicators system for land reclamation in mining subsidence area with higher level of underground water .System Dynamics (SD Act) , net cash flow ,income approach ,value of ecosystem services and other methods are used to estimate the value associated benefits .In this paper ,Qidong Mine reclamation project as an example to evaluate the effectiveness of land reclamation ,including economic ,ecological and social benefits .It proves to be feasible to evaluate quantitatively the overall efficiency if appropriate evaluation methods are used .And it also has important practical significance and application value for promoting land reclamation work when the benefits of all stakeholders are clearly in the project of land reclamation .%高潜水位矿区塌陷土地复垦效益是投资决策的重要依据之一，本文在祁东煤矿复垦项目调查的基础上，借鉴复垦效益评价文献，建立适宜高潜水位矿区塌陷土地复垦效益评价的指标体系，运用系统动力学（S D法），净现金流法，收益还原法和生态系统服务价值法等方法估算相关效益值，并以祁东煤矿复垦项目为例，对土地复垦效益进行评价，包括经济效益、生态效益和社会效益的评价，表明采用适宜的评价方法进行定量化研究其综合效益的可行性，明确塌陷土地复垦各利益相关方的效益值，对于土地复垦工作的推进具有重要的现实意义和应用价值。
