摘要
结合银川市市情,在参考生态城市、节水型城市具体指标体系的基础上,提出了银川市生态系统健康评价指标体系。利用模糊数学建立城市生态系统健康评价模型,通过层次分析法和专家打分相结合的方法确定各因子的具体权重。通过计算得出银川市城市生态健康状况值,以此对银川市生态系统健康状况进行了评价。
Whether urban ecosystem system is healthy or not affects the safety of the ecology in arid, the assessment of urban ecosystem health have realistic meaning. Combine the index system of ecocity and the model of economical water resources of city, put forward the ecosystem health of Yinchuan City. Establish the model of city ecosystem health assessment through the fuzzy mathematics, and confirm the power of each factor by AHP and expert mark.At last, the author calculates the subjection degree of Yinchuan City in 2003, comes to a conclusion that the ecosystem health condition of Yinchuan City represent the ill-health appearance, because the consumption of resources and energy sources too higher, the third industry develops not enough sound etc.
