摘　　要：综合考虑城市河流的物理构造特征、水文特征、社会经济状况等因素,构建城市河流生态健康评价指标体系和评价等级标准,建立起基于改进的模糊层次分析法与可变模糊集理论的城市河流生态健康评价方法,并以郑州市内两条河流作为样本进行研究。结果表明,完成部分水景观建设的河流段处于亚健康偏向疾病状态,未经过水景观建设的河流段处于疾病偏向亚健康状态,两者均需要加大水景观建设、治污力度以逐步恢复到健康状况。计算结果与实际情况相符,表明水景观建设对城市河流生态健康的恢复有重要作用。By comprehensively considering the physical structural characteristics, hydrological characteristics, socio- economic status and other factors of urban rivers, the index system and grading criterions for evaluating urban river ecology health are established and the evaluation method of urban river ecology health is then created based on improved fuzzy AHP method and variable fuzzy set theory. Taking two rivers in Zhengzhou City as study cases, the results show that the river section which has partly completed the construction of water landscape is classified into Class Sub-health to Disease, whereas the river section which has not completed the construction of water landscape is classified into Class Disease to Sub-health. The construction of urban water landscape and the measures of pollution control must be taken in order to improve sub-health state of two rivers. The results are consistent with actual situation and verify the construction of water landscape being important to repair urban river ecology health.
