DIVERSITY OF FOREST SOIL ANIMALS IN THE EASTERN MOUNTAIN REGIONS OF CHINA

According to a series of research information of soil animals in the eastern regions of China in recent twenty years, this paper analyses the diversity and distribution in time and space pattern of forest soil animals in these regions The diversity is influenced by human activities. Aimed at revealing distributive law of the diversity and promoting research on the diversity and its function within ecological systems in these region, it will provide ascientific basis for further protection and rational utilization. Conclusions of this paper are as follows: Forest ecological environments having high heterogeneity in the eastern mountain regions of China, diversity of soil animals is very abundant. Moreover, there are obvious changes in time and space pattern of soil animal diversity. On space pattern, because of different geographic positions of mountains, the diversity of forest soil animals exists distinctly is general higher in district forest than in other ones in the structure of mountain vertical zones, and it decreases with increasing of the depth in soil and there is feature of soil animal congregating to surface horizon. With season changing, soil animal diversity is lower in spring and summer than in autumn and winter in the forest of tropical and subtropical mountain regions, while it is higher in spring and autumn than in winter from warm temperate to cold Temperate zone, it is the highest in summer. The more the human disturbance is and the worse the ecological environment is,the lower the soil animal diversity is.
