| 摘要: |
| 为了科学评价煤矿废弃地植被恢复潜力，进而确定不同废弃地间植被恢复的优先顺序，根据土壤、地形、气候、废弃地现状各方面因素对植被恢复难易程度的影响，建立了各因素的隶属度函数；将三标度打分法与层次分析法相结合，确定了各因素的权重；采用模糊综合评价一灰色关联优势分析的方法，建立了煤矿废弃地植被恢复潜力评价模型。对辽宁阜新市矿区煤矿废弃地植被恢复潜力进行了评价，评价结果与实际情况相符。该模型能够为确定矿区植被恢复的难易程度以及优先顺序提供决策支持。 |

| Abstract: |
| A potentiality evaluation model for revegetation of abandoned land from mining activities was developed for identifying the difficulties and the priority of rehabilitation in different regions. Many factors, such as soil quality, climate, landform and the situations of the abandoned land, are involved in this model. The fuzzy function of every factor was built based on the analysis of its effect on revegetation. A fuzzy integrated evaluation algorithm was developed as the primary algorithm in this model. Fu Xin colliery, Liao Ning province in northeast China was selected as the objective of this case study. The evaluation results proved the method useful from the pilot use. |
