A PRELIMINARY STUDY ON COMPONENT AND ECOLOGI-CAL DISTRIBUTION OF SOIL ANIMAL IN JILIN PROVINCE
吉林省土壤动物组成与生态分布的初步研究

From June to August 1989, we investigated soil animal in 9 types of landscape in Jilin province. Soil animal of 111 sorts, individual number of which amounts of 22 653, have been collected. They belong to 6 Phyla, 13 Classes, 23 Orders and 72 Families. Generally, group number and individual number of soil animal are larger in forest than in grassland and desert. By cluster analysing, larger soil animal can be classified 5 sorts, middle and small soil animal can be classified 4 sorts. Group number and individual number of soil animal decrease wifh the deepening of soil. In the last of the paper, distributive characteristic of 5 main sorts of soil animal is approached.
