This study explores the relationship between landscape features and avian diversity in South Korea, examining both taxonomic and functional diversity. The Korean Peninsula serves as a pivotal habitat for resident bird species and a migratory pathway in the East Asia-Pacific flyway. Using a national dataset with block sizes ranging from 3.5 to 4.5 kilometers per side, we found that less urbanized open plains exhibit higher taxonomic diversity, while coastal regions with diverse water bird populations show higher functional diversity. These findings underscore the significance of conserving the existing land types and qualities in specific regions to substantially impact bird distribution and regional biodiversity. Remarkably, closed forests display diversity patterns akin to urban/built-up areas, despite their disparate land use characteristics. The stability of bird diversity indices across different land use types enables us to predict bird diversity indices based on the particular land use and land cover configurations. This study emphasizes the complementary nature of functional biodiversity indices in comprehending bird distribution patterns alongside taxonomic diversity indices.
本研究旨在探讨韩国景观特征与鸟类多样性之间的关系，同时考察了分类多样性和功能多样性。朝鲜半岛是居住鸟类物种的关键栖息地，也是东亚-太平洋飞行航道的迁徙通道。本研究使用了一个全国性数据集，其区块大小为每边 3.5 至 4.5 公里，结果表明，城市化程度较低的开阔平原表现出更高的分类多样性，而拥有多样化水鸟种群的沿海地区则表现出更高的功能多样性。这些发现强调了保护特定地区现有土地类型和质量的重要性，这将对鸟类分布和区域生物多样性产生重大影响。值得注意的是，尽管封闭森林的土地利用特征与城市/建成区截然不同，但它们的多样性模式却与之相似。不同土地利用类型的鸟类多样性指数的稳定性使我们能够根据特定的土地利用和土地覆盖配置来预测鸟类多样性指数。本研究强调了功能生物多样性指数在理解鸟类分布模式方面与分类多样性指数的互补性。
