摘要
1989年6—8月,作者对吉林省九种景观类型的土壤动物进行了调查,共获土壤动物111类、22653只,分隶于6门、13纲、23目、72科。从总体上看,土壤动物类群数和个体数是森林环境高,而草原、沙地环境低。通过聚类分析,将大型土壤动物归为五类,中小型土壤动物归为四类。土壤动物的类群数和个体数随土壤深度的增加而递减。本文还探讨了五种主要土壤动物的分布特点。
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.
