摘要
建立了多层次多指标的矿区生态系统健康综合评价体系,并给出矿区生态系统健康等级标准以及相应评价指标的量值。应用物元概念和可拓集合关联函数,并采用层次分析法确定各评价指标的权重,构建矿区生态系统健康的可拓评价模型。将该模型应用于大同矿区的生态系统健康评价。通过关联度计算,得出该矿区生态系统健康的综合关联度为?0.023,健康等级为Ⅲ级,属于合格水平。该可拓学评价方法能够准确、科学地区分矿区生态系统健康的等级,为矿区生态系统保护措施的制定提供依据,具有实用性。
A multi-hierarchy and multi-index comprehensive evaluation system of mining ecological health is es-tablished,and the health grade standard and the corresponding range of index are suggested as well.Based on mat-ter element theory and the dependent function of extenics set,using analytic hierarchy process to determine the weight of every evaluation index,the extenics evaluation model for mining ecological health is proposed.The model is applied to evaluate the ecosystem health of Datong mining area.It is obtained that the comprehensive correlation is ？0.023 and health grade is III,belong to qualified level.The extenics evaluation method can distin-guish the health grade of mining ecological health accurately and scientifically,provide the basis for formulating protection measures,so the method is practicable.
