矿区生态系统健康评价的理论和方法

Theory and method of ecosystem health assessment in a mining area

分析了矿区生态系统健康内涵,建立了评价指标体系,以模糊评价理论对矿区生态系统健康现状、以灰色预测和趋势函数法对矿区生态系统健康的发展趋势、以非线性理论对矿区生态系统的稳定性进行了评价,在此基础上提出了综合评价方法.实例研究的结果表明, 研究矿区生态系统处于亚健康状态,需要对其进行干预和调控.并提出了相应的对策和建议.

Based on the connotation of ecosystem health in a mining area and an index system for assessment established, the status quo of ecosystem health was assessed by the fuzzy theory and its tread in development was predicted by the grey theory. The non-linear theory was applied to assess the stabilities of the ecosystem and a comprehensive assessment method was proposed. The results show that the situation of ecosystem health in the investigated mining area is sub-healthy. It is necessary to adjust and control the situation and some measures were recommended.
