中文摘要 为探究栖息地生境格局对候鸟群落结构的影响，判定引起候鸟群落波动的驱动力指标及与候鸟迁徙活动相关性较高的关键生境因子，本文以大沽河河口湿地为研究区，采用景观格局指数与适宜性分析相结合的方法，系统分析大沽河河口湿地生境格局的演化特征及候鸟群落的响应机制。结果表明：1）研究区候鸟种类和数量均不同程度的减少，候鸟群落多样性显著降低。2）研究区生境格局破碎度不断加深，多样性与异质性逐步降低，适宜候鸟栖居的空间逐步缩减。3）景观水平上，对候鸟迁徙活动的影响度排序结果为破碎度指标>多样性指标>聚散度指标>连通度指标。4）类型水平上，对候鸟栖息环境及迁徙活动影响度较高的生境为农田、盐沼植被群落和裸地。综上，城市化和人类开发活动是造成区域生境格局演变及候鸟群落结构波动的重要因素。

英文摘要 In order to explore the impact of habitat pattern on the structure of migratory bird community and determine the index of driving force causing the fluctuation of migratory bird community and the key habitat factors with high correlation with migratory bird migration, this paper takes Dagu River estuary wetland to systematically analyze the evolution characteristics of its habitat pattern and the response mechanism of migratory bird community using the method of combining landscape pattern index and suitability analysis. The results are as follows:1) The species and number of migratory birds in the study area decreases to varying degrees, and the diversity of migratory bird community decreases significantly; 2) The habitat pattern in the study area is increasingly fragmented, with decreased diversity and heterogeneity and smaller spaces suitable for migratory birds; and 3) At the landscape level, the ranking results of the impacts on migration activities of migratory bird are as follows:fragmentation index > diversity index > convergence divergence index > connectivity index; and 4) At the type level, farmland, salt marsh vegetation community and bare land have a high impact on habitat environment and migration activities of migratory birds. In conclusion, urbanization and human development activities are important factors to the evolution of regional habitat pattern and the fluctuation of migratory bird community structure.
