SOIL ANIMAL COMMUNITY DIVERSITY IN THE FOREST OF THE SOUTHERN SUBTROPICAL REGION,CHINA
南亚热带森林土壤动物群落多样性研究

Soil animal community diversity in Dinghushan Nature Reserve,as an example of the southern subtropical region of China were studied.the diversity measuring methods Gower coefficient, H' index and DG index(which was suggested by LIAO in1990)etc.were compared.The Gower coefficient and DG index were proposed on base of the hypothesis that every species has equal independence and importance in the community,and can be compared intercommunitily.So measurement of the complicated soil animal community diversity may be carried out.The calculation of DG index is easy and simple.There are bigger soil animal community diversity and more tropical characteristics in southern subtropical region of China than in middle subtropical region of China.There is soil animal community composition variance between the two regions.The soil animal community composition in varied conservation degrees were compared.The results show:the better the forests were protected,the higher the community diversity was.But,soil animal community diverdity in climax forest community may become lower.
