【摘要】 论述了矿区生态系统健康评价指标体系设置的理论依据,构建了以生态环境保障度、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及指标计量模型,探讨了运用层次分析法并通过熵技术修正的确定评价指标权重的新方法,建立了矿区生态系统健康评价的模糊综合评价模型,并在某矿区进行了检验.更多还原

【Abstract】 The theoretical basis of building indicator system for ecosystem health assessment in a typical mine area was discussed. The muti-layer indicators of ecosystem health assessment and their quantitative models were given, in which the guideline-layer consists of the ensuring degree of ecosystem and environment, supporting degree of natural resources, developing level of economy and society, sustainable degree of ecosystem health. Then thenew methods of determining indicator weight were studied, which was determined by analytic hierarchy process(AHP) and modified by entropy technology. Further, the fuzzy synthetic judgment models of ecosystem health assessment were described, and tested in a typical mine area.更多还原
