The purpose of this study is to investigate the response of the soil mesofauna and ground-dwelling arthropods to vegetation structure and composition in a mountain pasture. The pasture mainly comprised five types of plant communities; Agrostis alba - Phleum pratense community, Poa pratensis community, Festuca ovina community, Rumex acetosella community, and the shrub assemblage comprised Spiraea miyabei-Spiraea salicifolia community. Soil chemical properties including the pH, EC and nutrient levels were influenced by plant communities. Plant-specific responses were observed for bacteria-feeding and plant-feeding soil nematodes. Collembola and Oribatida having the same feeding habit were influenced differently by plants. nMDS showed that the community of ground-dwelling arthropods were separated by vegetation types. Species numbers of arthropods were different among different plant communities. Our results indicate that vegetation structure and composition can influence both abundance of diversity of terrestrial fauna.

본 연구는 2003년 8월부터 2005년 12월까지 농촌진흥청 난지농업연구소의 기존 혼파 방목초지(해발 200m)에서 실시하였으며 방목 혼파초지에 우분퇴비 시용에 따른 사초생산성 및 토양 개선 효과를 구명하기 위하여 수행되었다. 화학비료 단용구, 우분퇴비 단용구, 화학 및 우분퇴비의 시용수준, 화학비료와 퇴비의 연차별 교호시용 등의 처리를 두어 우분퇴비 시용이 혼파초지의 사초생산성 및 토양성분에 미치는 영향을 조사하였다. 연간 총건물수량을 비교해보면 시
