土地复垦对矿区土地资源可持续利用的影响

运用生态足迹法分析了平朔矿区2005年生态承载力状况；通过改变土地利用结构，模拟出3种不同条件下的生产性土地配置情景：①破坏土地无复垦措施情景，②破坏土地采取生态效益优先情景，③破坏土地实行耕地优先情景，计算得出矿区煤炭资源开发对生态承载力的影响和人为干预下生态承载力的恢复程度。通过设置4种模式：土地适宜模式、提高生态生产性土地面积模式、提高单位土地面积产量模式、不同程度的资金投入模式，计算矿区生态承载力，为矿区土地复垦和复垦土地的可持续利用提供了理论依据。

Impact of Land Reclamation on Sustainable Utilization of Land Resources in Mining Area

Ecological capacity of Pingshuo mining area in 2005 was calculated through the ecological footprint analysis.The productive land use structures under three different conditions are simulated through changing the structure of land utilization：1.The damaged land without any countermeasures；2.The damaged land with the prior reclamation of the eco-efficiency; 3.The damaged land with prior reclamation of farming.Then the influence of coal resources development in mining area on the ecological capacity and the recovery of the ecological capacity with human intervention are calculated.Four reclamation models are set up，that is，the land suitability mode，the ecological productive land area improvement mode，the production improvement mode for per unit land，the different capital investment mode.Then the ecological capacities in mining area are calculated with the four modes above，thus providing a theoretical basis for the land reclamation and the sustainable utilization of the reclaimed lands.
