摘　　要：生境破碎化会造成种群面临局地灭绝风险,而生境绿道的构建有利于增强生境之间的连接.以绿翅鸭为研究对象,采用最小费用模型构建的分析方法,解析了生境绿道构建的思路,形成了辽河三角洲水禽生境绿道构建的方案,分析了辽河三角洲生境绿道现状存在的问题,提出了相应的生态解决措施.The habitat corridors are pivotal instruments to boost the connectivity among habitats and mitigate the negative impact of habitat fragmentation--population is faced the risk of extinction in part. Anas crecca was taken as the object of study to analyze the process of the construction of the waterfowl habitat corridors in Liaohe River Delta. The least-cost model was adopted to construct the project of the waterfowl habitat corridors in Liaohe River Delta. Some problems of the corridors were analyzed, and some ecological measures were offered.
