摘　　要：为检验潮汐河口生态航道建设水平,开展潮汐河口生态航道评价研究。根据潮汐河口自然条件、生态环境、航道属性等特征,分析潮汐河口生态航道内涵特征,提出生态航道评价指标体系,并以长江口南槽航道为例选取适宜指标进行航道健康水平评价。结果表明,航道治理一期工程实施后南槽航道健康指数0.884 6,为良好状态;工程后南槽河势条件、航道条件明显改善,通航条件和涉水功能的状态良好,生境与生物状况处于中等水平,与河口整体生态环境背景状态一致;南槽生态航道建设成效显著。To test the ecological waterway construction level in the tidal estuary, we carry out the evaluation study. According to the natural conditions, ecological environment and channel attributes of tidal estuary, we analyze the connotation characteristics of tidal estuary ecological waterway and put forward an evaluation indicator system for it. Taking the South Passage of the Yangtze River Estuary as a case, we select appropriate indicators and evaluate the waterway health index. The results show that the waterway healthy index value of the South Passage after the first phase of navigation channel regulation project is 0.884 6,reaching good level. The regulation project greatly improves the conditions of river regime and enhances the channel conditions. Navigating conditions and water-related function are pretty good. Habitat and biological conditions are in the middle level, consistent with the ecological environment background state of the Yangtze River Estuary. The effect of ecological waterway construction in South Passage is remarkable.
