Response of functional groups of soil animals to seasonal dynamics in Heishiding nature reserve

To understand the response of functional groups of soil animals to seasonal dynamics in Heishiding nature reserve vegetation，we studied index of groups，individuals，diversity，evenness，dominance and richness of functional groups of soil animals under four kinds of vegetation（ tea，farmland，shrub and tree）. The results showed that a total of 1 718 soil animals were captured in four seasons，belonging to 4 families and 9 groups，and soil animal community according to different functional composition was divided into 5 classes，namely，phytophagous， saprophagous，dryness，predatory and omnivorous. Among them，4 classes of Nematode，Acarina，Isotomidae and Isoptera were dominant groups；In addition，phytophagous soil animals accounted for 4.07% of total catch，25.96% of saprophagous soil animals，28.7% of dryness soil animals，8.67% of predatory soil animals and 32.6% of omnivorous soil animals. The number of soil animals in different vegetation was not significantly different，but the soil animals under tea and trees responded to seasonal variation.
