摘要:

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27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  88.67%,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~定的关系,主要土壤类型表层中动物密度为:黑色石灰土中 125.6万个/m3,棕色石灰土中 104.3万个/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

Abstract: A preliminary study on diversity of soil animal communities in the forest of Badagong Mountain Nature Reserve was made , and 27 species of soil animals were found , belonging to 12 classes of five phyla , of which Acarina , Collembola , Nematoda and Enchytraeidae were dominant communities , accounting for 88.67 %of the total hunted ones. There existed a certain relationship between animal density and the type and nature of soil. The density of animals in the main soil types were as follows : 1.256 million ind./m3 in the black limestone soil , 1.043 million ind./m3 in the brown limestone soil , 912 000 ind./m3 in mountain soddy yellow- brown earth and 742,000 ind./m3 in mountain yellow- brown earth.
