Community structure and guild feature of soil arthropod animal in different forest types in the West Lake mountainous area in spring, Hangzhou
In May 2009, a survey of soil arthropod communities was conducted in five typical types of forest communities in West Lake mountainous area by pitfall traps.6 891 soil arthropod fauna individuals were sam-pled, which were classified into 24 groups.Group numbers of soil arthropod communities in five forest types were significantly different.Deciduous broadleaved forest had the highest αdiversity indices of soil arthropod community, while the bamboo forest had the lowest indices.The S?rensen similarity coefficients of soil arthro-pod communities in different forest types changed little, while the Morisita-Horn similarity coefficients varied greatly.The saprozoic group accounted for 35.15%of the arthropods.The results showed that: coleopteran,hymenoptera , collembola and psocoptera constituted the dominant group of soil arthropod fauna;soil arthropod fauna in deciduous broadleaved forest had the most complicated community structure, while the bamboo forest had the simplest; analysis of S?rensen and Morisita-Horn similarity coefficients showed that different forest types had little effect on community structures, but had a great impact on relative abundance; the saprozoic group formed the main body of guilds in study area.
