摘要: 为探究江苏盱眙铁山寺国家森林公园及其周边鸟类群落现状及其季节动态变化, 于2023年5月至2024年1月采用固定样线法对公园及其周边鸟类组成和多样性进行了调查。共记录到鸟类1 830只, 隶属于11目31科71种, 其中包括3种国家二级重点保护鸟类。从动物区系上看广布种居多, 兼有东洋界和古北界的物种; 从居留型看候鸟和旅鸟超过记录总种类数的一半, 表明研究区在鸟类迁徙路线上占据重要位置。季节性变化显示春夏季鸟类物种丰富度和多样性较高, 秋冬季鸟类数量较高。此外, 不同季节间鸟类群落组成也具有显著差异(P < 0.05)。从食性集团来看, 夏季鸟类群落中食虫类鸟类比例显著增加, 食植类鸟类主要出现在春季, 而杂食性鸟类则全年占据主导地位。这些结果揭示了食物资源的季节性波动对鸟类分布的影响, 同时也反映了不同功能群鸟类间的生态适应性差异。基于研究结果, 建议通过优化植被结构、推广可持续农业措施以及建立长期监测体系等手段来提升铁山寺国家森林公园及其周边地区的鸟类栖息地质量, 从而有效保护当地的鸟类资源和生物多样性。Abstract: To investigate the current status and seasonal dynamics of the bird community in the Tieshan Temple National Forest Park and its surrounding areas in Xuyi County, Jiangsu Province, this study conducted a survey of bird composition and diversity using the fixed transect method from May 2023 to January 2024. A total of 1 830 birds were recorded, belonging to 71 species, 31 families and 11 orders, including three species under national second-class protection. In terms of fauna, widespread species predominated, with a mix of Oriental and Palearctic species. Migratory and passage birds accounted for more than half of the total recorded species, indicating the park's significant role in bird migration routes. Seasonal variations revealed higher species richness and diversity in spring and summer, while bird abundance was higher in autumn and winter. Additionally, significant differences in bird community composition were observed across seasons. From the perspective of dietary guilds, the proportion of insectivorous birds significantly increased in summer, herbivorous birds were primarily observed in spring, and omnivorous birds dominated throughout the year. These findings highlight the impact of seasonal fluctuations in food resources on bird distribution and reflect differences in ecological adaptability among different functional groups of birds. Based on the results, optimizing vegetation structure, promoting sustainable agricultural practices and establishing a long-term monitoring system are recommended to enhance the quality of bird habitats in and around the Tieshan Temple National Forest Park, thereby effectively conserving local bird resources and biodiversity.
