Bird assemblages are sensitive to changes in landscape composition and the environment, such as those that result from drought. In this study, the relationship between landscape composition and avian functional diversity in traditional agricultural ecosystems in the Civilian Control Zone (CCZ) of Korea was examined. In addition, the resilience of biodiversity to changes in landscape elements resulting from drought conditions was investigated. The traditional agricultural landscape (TAL) of the sites studied was divided into three types: TAL 1 had a high proportion of rice paddies, TAL 2 included large forest areas, and TAL 3 represented areas with drylands. Of these, TAL 1 showed the highest species richness and functional richness, but these measures were most vulnerable to drought. Meanwhile, TAL 2 showed that the bird communities were more tolerant under drought event. This study shows that to conserve and enhance the diversity of birds in traditional agricultural landscapes of Northeast Asia, active management of forest areas is needed to protect bird populations. In addition, commercial pressures to develop this area will require urgent biodiversity conservation plans to protect the unique biodiversity of the Korean CCZ. This study thus provides landscape management guidance for conservation planning.

传统农业景观对韩国非军事区附近鸟类功能多样性的结构影响

鸟类聚集对景观组成和环境的变化敏感，例如干旱造成的变化。在这项研究中，考察了韩国民用控制区（CCZ）中传统农业生态系统中景观成分与鸟类功能多样性之间的关系。此外，还研究了生物多样性对干旱条件引起的景观要素变化的适应力。研究地点的传统农业景观（TAL）分为三种类型：TAL 1的稻田比例高，TAL 2的林地面积大，而TAL 3的地区则是旱地。其中，TAL 1具有最高的物种丰富度和功能丰富度，但这些措施最容易受到干旱的影响。与此同时，TAL 2表明，鸟类群体在干旱事件下更具耐受性。这项研究表明，要保护和增强东北亚传统农业景观中鸟类的多样性，就需要积极管理森林面积以保护鸟类种群。此外，开发该地区的商业压力将需要紧急的生物多样性保护计划，以保护韩国CCZ独特的生物多样性。因此，这项研究为保护规划提供了景观管理指导。开发该地区的商业压力将需要紧急的生物多样性保护计划，以保护韩国CCZ独特的生物多样性。因此，这项研究为保护规划提供了景观管理指导。开发该地区的商业压力将需要紧急的生物多样性保护计划，以保护韩国CCZ独特的生物多样性。因此，这项研究为保护规划提供了景观管理指导。
