摘　　要：本研究以黑岱沟露天煤矿为研究对象,通过研究草灌乔结合、草灌、灌木、牧草和农田复垦模式,对不同复垦模式进行了投资效益分析与评价。结果表明:牧草复垦模式投资成本最低,草灌乔复垦模式和欧李复垦模式投资成本较高;对不同复垦模式综合分析对比,不同复垦模式各具特点;综合分析生态效果、投资成本、土地条件要求、生物价值和财务能力,认为牧草复垦模式和欧李复垦模式优势明显,农作物复垦模式劣势明显;考虑到在可利用耕地的作用效果,农作物复垦模式优势明显,直接增加了可利用耕地面积;草灌乔复垦模式提升复垦区生态系统稳定性上效果最佳。因此,各种复垦模式优缺点明显,需要根据实际情况斟酌使用。In this study,the authors analyze and evaluate different reclamation systems by the investment-benefit in Heidaigou opencast coal mine area,and the reclamation system including the combination vegetation of herb,shrub and tree,herb and shrub mixed vegetation,shrub vegetation,herb vegetation and farming vegetation.The results show that：the investment of grass vegetation reclamation system is lowest among the 5 reclamation systems,and the combination vegetation of herb,shrub and tree,grass and shrub mixed vegetation was much higher compared with other reclamation systems;the different reclamation systems show different characteristics by investment-benefit analysis and evaluation;comprehensive analysis of ecological effects,investment costs,land conditions,biological value and financial capacity,herb and shrub vegetation reclamation system show advantages compared with other reclamation systems,and farming vegetation reclamation system show disadvantages;considering the effect of reclamation system on available arable land,farming vegetation reclamation system show obvious advantages by increasing the arable land area;the combination vegetation of herb,shrub and tree reclamation system show the best beneficial in improving stability of the local ecosystem.Therefore,the advantages and disadvantages of different reclamation systems are obvious,and need to be according to the actual situation.
