对八大公山自然保护区森林土壤动物群落的多样性进行了初步研究 ,共获得 2 7类土壤动物 ,隶属 5门 12纲 ,其中螨类、弹尾类、线虫类和线蚓类为优势类群 ,占全捕量的 88.6 7% ,是该区土壤动物的主体。土壤动物密度与土壤类型和土壤性质有一定的关系 ,主要土壤类型表层中动物密度为 :黑色石灰土中 12 5.6万个 /m3,棕色石灰土中 10 4 .3万个 /m3,山地生草黄棕壤中 91.2万个 /m3,山地黄棕壤中74 .2万个 /m3。 A preliminary study on the diversity of soil animal community in Badala Nature Reserve included 27 species of soil fauna, belonging to 5 classes and 12 classes. Among them, mites, flies, nematodes and earthworms belonged to the dominant group , Accounting for 88.6% of the total catch, is the main body of soil fauna in the area. The density of soil animals is related to the soil type and soil properties. The density of the animals in the surface layer of main soil types is 125,600 / m3 in black limestone soil, 104,000 / m3 in brown limestone soil, 91.2 thousand / m3 in yellow brown soil and 74.2 thousand / m3 in yellow mountain brown soil.
