文摘内容 Soil animal communities of Pinus koraiensis broad-leaved mixed forest were studied. The purpose was to discuss the dynamic characteristic of soil animals and relationship with environmental factors. The ecosystem geography distribution law of soil animals, soil animals' role and function in ecological system were revealed. In June, August, October each year, three plots were selected. In each plot, four layers were sampled( litter layer,0 - 10 cm, 10 - 20 cm & 20 - 30 cm), adding up to 72 soil sample. The area for large-sized soil animals was 50 cm × 50 cm, and the area for middle-small-sized soil animals was 10 cm × 10 cm. Separated soil animals through adopting hand-picking method and Tullgren method respectively. Sampled the soil animals in two continuing years. Shannon-Wiener index was adopted to analyze the diversity of soil animals. Monad liner regression was used to search the relationship between soil animals and environmental factors. The dominant groups were Oribatida, Isotomidae. There were relatively great changes in groups and individual numbers of dominant groups and rare groups when the reason changed. The individual numbers of dominant groups and the groups of rare groups changed. The number of individual and group was the most in August. Obviously it correlated with climatic factors in middle temperate zone. The evenness was low and dominance was high. The diversity index was not most. Among the annual fluctuating there was a increasing trend. The evenness was low and dominance was high. The diversity index was low. It conformed with the law of reason change. The correlation between soil animals and atmospheric temperature, rainfall, ground temperature and sunlight showed the correlation with rainfall and soil temperature was the most significant。
