我国典型资源枯竭型城市生态系统健康综合评价

资源枯竭和环境恶化影响着典型资源枯竭型城市的发展。根据压力-状态-响应模型,构建了一个度量典型资源枯竭型城市生态系统健康水平的含有4个层次35项具体指标的指标体系,并运用客观的改进的熵值法赋权、模糊综合评价法及划分的等级标准对我国9个典型资源枯竭型城市的生态系统健康水平进行量化分析。结果表明,阜新市的生态系统健康水平属于较健康级,伊春、辽源、白银、焦作属于临界状态级,盘锦、白山、萍乡属于较不健康级,而石嘴山则属于不健康级。典型资源枯竭型城市的生态系统健康水平总体上不容乐观。

Synthetic Assessment of Ecosystem Health on Typical Resource-Exhausted Cities in China

The development of typical resource-exhausted cities is influenced by exhausted resources and degraded environment.An assessment index system of ecosystem health on typical resource-exhausted cities is set up based on Pressure-State-Response model,which includes 4 hierarchies and 35 concrete items.The nine typical resource-exhausted cities are taken as the cases to assess their ecosystem health levels by using improved entropy method and fuzzy synthetic assessment method.The result shows that ecosystem heal...
