八大公山自然保护区森林土壤动物群落多样性的初步研究

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一定的关系，主要土壤类型层中动物密度为：黑色石灰土中１２５．６万个／，棕色石灰土中１０４．３万个／ｍ＾３，山地生草黄棕壤中９１．３万个／ｍ＾３，山地黄棕壤中７４．２万个／ｍ＾３。

A preliminary study on diversity of soil animal communities in the forest of Bad agong Mountain Nature Reserve

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./m 3 in the black limestone soil, 1.043 million ind./m 3 in the brown limestone soil, 912 000 ind./m 3 in mountain soddy yellow_brown earth and 742,000 ind./m 3 in mountain yellow_brown earth.
