摘    要:基于航道建设要素与河流生态系统保护相协调的基本思想, 建立长江中下游武汉?安庆段生态航道评价指标体系。利用层次分析法和能够反映木桶效应的综合指数评价法, 对该河段2018年生态航道健康水平进行评价。结果表明, 武汉?安庆段的生态航道健康指数为0.8145, 属于中等水平, 该航道的自净功能优秀, 航运、泄洪和景观娱乐功能良好, 生态功能较差, 后续航道建设和维护应该加强水生态保护与修复工作。

关 键 词:生态航道  武汉?安庆段  评价体系  层次分析法

Abstract:Based on the principle of the harmonious relationship between navigation and river ecosystem protection, an evaluation indicator system for Wuhan-Anqing Reach in the middle-lower of the Yangtze River was constructed. With analytic hierarchy process (AHP) and the comprehensive evaluation index method considering the bucket effect of individual function to the whole system health, the ecological health condition of Wuhan-Anqing Reach in the year of 2018 was evaluated. The results showed that the waterway health index was 0.8145, indicating a fair level. The self-purification function graded excellent, and the navigation function, flood discharging function as well as landscape & entertainment function were good, while the ecological function was poor. The results suggested that ecological protection and rehabilitation should be strengthened in the process of future waterway regulation projects.
Keywords:ecological waterway  Wuhan-Anqing Reach  assessment system  analytic hierarchy process
