摘要
土地利用和植物入侵会影响生物多样性。韩国济州岛是联合国教育、科学及文化组织指定的生物圈保护区,了解土地利用类型和入侵植物对生态系统的影响对于更好地管理济州岛和制定增加生物多样性的战略计划至关重要。本研究调查了最主要的外来入侵物种 Hypochaeris radicata 对济州岛四种土地利用类型的影响。比较了四种土地利用类型(耕地、绿地、荒地和住宅)的植物组成、土壤特性和植物多样性。在土地利用类型中,耕地的植物组成最为多样,外来和本地植物物种的丰富程度也最高。耕地(如广泛分布于济州岛的橘子园)的植物多样性最高,这是因为清除杂草造成了中等强度的干扰。不同土地利用类型的 H. radicata 相对覆盖率并无差异。但是,H. radicata 的入侵与植物物种丰富度呈负相关,因此这种入侵物种对土地利用区的本地草本植物的生物多样性构成了威胁。H. radicata能适应各种土壤特性和各种土地利用类型的地区。因此,对土地利用类型和植物入侵模式进行监测至关重要,以指导实施一致的管理和保护战略,维护济州岛已改变栖息地生态系统的完整性。
Effects of land-use types and the exotic species, Hypochaeris radicata, on plant diversity in human-transformed landscapes of the biosphere reserve, Jeju Island, Korea
Land-use and plant invasion influence biodiversity. Understanding the effects of land-use types and invasive plants on the ecosystem is crucial for better management and the development of strategic plans for increasing biodiversity in Jeju Island, Korea, a designated Biosphere Reserve by the United Nations Education, Scientific, and Cultural Organization. The effect of the most dominant invasive exotic species, Hypochaeris radicata, on the four land-use types of Jeju Island was investigated. Plant composition, soil characteristics, and plant diversity among four land-use types (cropland, green space, neglected land, and residential) were compared. Among the land-use types, croplands had the most diverse plant composition and the highest richness in exotic and native plant species. Croplands, such as tangerine orchards, which are widely distributed throughout Jeju Island, showed the highest plant diversity because of medium intensity disturbance caused by weed removal. The relative cover of H. radicata did not differ between land-use types. However, H. radicata invasion was negatively related with plant species richness, making this invasive species a threat to the biodiversity of native herbs present in land-use areas. H. radicata adapts to areas with a broad range of soil properties and a variety of land-use types. Therefore, it is crucial to monitor land-use types and patterns of plant invasion to guide the implementation of consistent management and conservation strategies for maintaining ecosystem integrity of the transformed habitat in Jeju Island.

期刊介绍:
Plant Diversity (formerly Plant Diversity and Resources) is an international plant science journal that publishes substantial original research and review papers that
advance our understanding of the past and current distribution of plants,
contribute to the development of more phylogenetically accurate taxonomic classifications,
present new findings on or insights into evolutionary processes and mechanisms that are of interest to the community of plant systematic and evolutionary biologists.
While the focus of the journal is on biodiversity, ecology and evolution of East Asian flora, it is not limited to these topics. Applied evolutionary issues, such as climate change and conservation biology, are welcome, especially if they address conceptual problems. Theoretical papers are equally welcome. Preference is given to concise, clearly written papers focusing on precisely framed questions or hypotheses. Papers that are purely descriptive have a low chance of acceptance.
Fields covered by the journal include:
plant systematics and taxonomy-
evolutionary developmental biology-
reproductive biology-
phylo- and biogeography-
evolutionary ecology-
population biology-
conservation biology-
palaeobotany-
molecular evolution-
comparative and evolutionary genomics-
physiology-
biochemistry
