摘要
探讨了矿区生态系统健康研究的现状及重要意义,界定矿区生态系统健康的内涵,阐述了矿区生态系统健康评价指标体系设置的依据,构建以生态环境保障度、自然资源支持度、社会经济发展度和健康可持续度为准则层的多层次评价指标体系。在此基础上,建立了矿区生态健康评价的未确知测度模型,并将信息熵理论引入指标体系的约简。最后,通过实例验证了该模型的可行性与有效性。
This paper firstly overviews the present rendition and important sense of ecosystem health research, defines the meaning of ecosystem health and formulates the theory basis of evaluating index set for ecosystem health in mineral area. Then builds a multi-levd evaluation index-system which made with ecological rendition, natural resource supporting degree, social and economy developing degree and health sustained degree as criterion level. On this basis, sets up the unascertained measure model and makes reduction on the index system through entropy measure. At last, an actual example is given to justify the feasibility and efficiency of the model.
