摘要
本次研究以模糊综合评判法为主,物元分析法为辅对本溪市水生态承载力进行了全面评价。研究结果表明,2010—2018年本溪市水生态承载力等级呈现出由“一般可承载”向“较强承载”转化的弱增强趋势。其中,水体BOD等6个指标对本溪市水生态承载力等级的保持具有重要贡献。工业氨氮年排量、水资源开发利用率、藻类细胞密度等9个指标成为制约本溪市水生态承载力等级提升的因素。
In this study,the fuzzy comprehensive evaluation method is mainly used,and the matter-element analysis method is used as a supplement to comprehensively evaluate the water ecological carrying capacity of Benxi City.The results showed that the water ecological carrying capacity of Benxi City showed a weak trend of transformation from“general carrying capacity”to“strong carrying capacity”during 2010—2018.Among them,six indicators including water BOD concentration have important contributions to the maintenance of water ecological carrying capacity in Benxi City.Nine indicators,such as annual industrial ammonia nitrogen discharge,water resource development and utilization rate,and algal cell density,have become the factors restricting the improvement of the water ecological carrying capacity of Benxi City.
