摘要
本文构建以矿区复垦土壤肥力状况、生态质量以及环境质量3个准则层20项指标为矿区复垦效果评价指标体系,为避免因素赋权的主观性,采用主成分分析法的方差贡献率确定各评价指标的权重,结合模糊综合评判方法建立各评价指标的隶属度函数,采用因子加权求和法计算矿区复垦效果的评价总分值。
A reclamation effect evaluation index system was built,which contains 3 levels 20 indicators,mine substrate fertility,ecological quality and environmental quality.Principal component analysis was used to determine the weight of each index in order to avoid the subjectivity of empowerment factors in the existing evaluation methods.The membership function of the evaluation index was established by fuzzy comprehensive evaluation method and the total score of mining substrate reclamation effect evaluation was calculated using factor-weighted sum.
