Comparative Study on Ground-dwelling Insect Communities Between Eucalyptus spp.Plantations and Adjacent Zonal Natural Forests in Yachang,Guangxi
摘要
Abstract
This study investigated ground-dwelling insect communities by using pitfall trap method in the above 3 forest types in Yachang Orchids Nature Reserve,Guangxi,and unraveled the role of plant communities,stand structure,soil and litter properties involved in the associated mechanisms.The results showed that the ground-dwelling insect diversity in Eucalyptus spp.plantations was significantly lower than that in non-karst nat-ural forests but greater than in karst natural forests.The ground-dwelling insect community composition of planta-tions was significantly different from those of karst and non-karst natural forests.Eucalyptus spp.plantations were dominated by Blattidae and Gryllidae.The non-karst natural forests were dominated by Gryllidae,Blattellidae,Reduviidae,Drosophilidae and Blattidae.The karst natural forests were dominated by Nitidulidae and Drosophil-idae.The difference in ground-dwelling insect community composition between Eucalyptus spp.plantations and non-karst natural forests was driven by plant community,seedling density and litter cover,explaining 74.46％of overall dissimilarity in ground-dwelling insect community composition between 2 forest types.The difference in ground-dwelling insect community composition between Eucalyptus spp.plantations and karst natural forests was driven by understory tree density,litter cover and litter nitrogen content,explaining 62.27％of overall dissimilar-ity in ground-dwelling insect community composition between 2 forest types.A reduction of understory plants leads to a reduction of ground-dwelling insect diversity in Eucalyptus spp.ecological public forests.关键词
