丁坝是常用的航道整治建筑物，在发挥整治功能的同时，也会影响所在河段的生态质量。丁坝对河段生态的影响机理比较复杂，通过改变流场、流速、水深和河床冲淤情况，影响河段生境质量，其中坝田间的回流区是控制生态影响有利或有害的关键水域。文章以西江底栖动物和鱼类对栖息地流速、水深和底质的要求为依据，分析西江广东段的虎跳门口门浅滩和界首滩浅段，以及北江洪奇门水道玉米地段航道整治工程中丁坝对河段生态的影响。最后从合理选择丁坝坝址和构建生态保护型丁坝两个方面提出生态保护对策。

Spur dike is a kind of frequently used waterway regulation structure. It plays regulation function,and influences the ecological quality of its located river reach. Influence mechanism of spur dike on the river reach ecol?ogy is quite complex,by changing the flow field,flow velocity,water depth and riverbed erosion or deposition condi?tions to affect the quality of river habitat. Recirculation region in spur dike field is a key water area of controlling the advantages or disadvantages of these ecological influences. According to flow velocity ,water depth and substrate requirement in the habitat of benthic animal and fish in Xijiang River,taking Hutiaomen entrance shoal and Jie?shou shoal reaches of Xijiang River in Guangdong,and the cornfield section of Hongqimen waterway of Beijiang River for example,the influences of practical spur dike projects on river reach ecology were analyzed. The ecologi?cal protection countermeasures focused on selecting dike site reasonably and ecological designing of spur dike were put forward.
