西南山区矿业城市生态基础设施综合评价

Synthetic assessment of ecological infrastruture on mining cities of the southwest mountainous area in China

针对矿业城市生态基础设施特点,以大气系统、绿地系统和水文系统为依据,建立了3个层次15项具体指标的指标体系,并运用层次分析法和综合指数法构建评价模型,对我国西南山区8个矿业城市的生态基础设施进行评价.结果表明,攀枝花生态基础设施属于较好等级,福泉、开阳、绵竹、江津、南川、个旧属于一般等级,六盘水属于较差等级,说明我国西南山区矿业城市生态基础设施水平总体不容乐观.

The evaluation indexes system was established on the basis of air system ,greenbelt system and water system from the mining town of the ecological infrastructure characteristics , which includes 3 hierarchies and 15 concrete items . Analytic hierarchy process （AHP） and the method of comprehensive index evaluation are applied to establish the evaluati miodel . T hen , it studied the quality and evolvement characteristic of ecological infrastructure in the case of eight on mining cities of the suthwest muntainous aea in China . Finally , it draw s a conclusion the quality of ecological infrastructure of Panzhihua remained with better grade ;Fuquan , Kaiyang , Mianzhu , Jiangjing , Nanchuang and Gejiu belonged to common grade;Liupanshui remained with poor grade , w hich indicates that overall ecological infrastructure of mning cities of the suthwest muntainous aea in China are relatively severe .
