长沙岳麓山森林生态系统中土壤动物群落结构的研究

STUDY OF THE SOIL ANIMAL COMMUNITY STRUCTURE IN THE FOREST ECOSYSTEM OF THE AREA OF THE YUELU MOUNTAIN IN CHANGSHA

长沙岳麓山地处中亚热带,气候温暖湿润,植被繁茂,在土壤中生活着大量土壤动物,以地带性常绿阔叶林和灌草丛群落中的土壤动物最丰富,其次是针叶林和针阔叶混交林。岳麓山土壤动物种类计有27类(目),隶属于4门10纲,其中以蜱螨目、弹尾目和线虫类占绝对优势成为优势类群,三者占整个土壤动物捕获量的92.26%,是森林土壤动物的主体。

The Changsha Yuelu Mountain is located in the middle subtropical zone.Theolimate here is warm and moist and the vegetation cover is lush.In the soil livea large amount of soil animals.First come soil animals growing in the zonaleveryreen broadleaf-forests and bushes-weeds,and second come the soil animals inthe coniferous forests and coniferous-broadleaved mixed forests.The soil animalpopulation in Yuelu Mountain amounts to twenty seven kinds(Order),which canbe divided into ten classes belonging to four phyla.Acarina,Collembola andNematoda occupy a dominant position,being superior population,The three kindsof soil animal are 92.26 of the total amount,wich is the main body of the soilanimals community in Yuelu Mountain.
