摘要/Abstract

摘要： 2000年10月～2001年10月对下辽河平原地区撂荒、林地、旱田、水田4种不同土地利用方式的土壤微节肢动物进行了调查.应用个体数密度、类群丰富度、多样性指数和均匀度4个群落参数,研究了土壤微节肢动物的群落结构和季节变化.结果表明,撂荒中土壤微节肢动物的4个群落参数均为最高,旱田均为最低,季节变化影响土壤微节肢动物的群落结构,但土地利用方式不影响群落结构的季节变化型.下辽河平原地区不同土地利用方式共鉴定出土壤微节肢动物12个类群,撂荒、林地、旱田中弹尾目(Collembola)和蜱螨目(Acarina)为优势类群,双翅目(Diptera)、鞘翅目(Coleoptera)和膜翅目(Hymenoptera)为常见类群,水田中弹尾目、蜱螨目和双翅目为优势类群,鞘翅目为常见类群.各土地利用方式、各季节均在表层土壤出现的类群最多、密度最高,中层次之,底层最少.

Abstract: The data on the soil micro-arthropodes under four land utilization types (fallow,forest,upland field and paddy) in the Lower Reaches of Liaohe River Plain were collected in a period from October 2000 to October 2001.Using the community parameters of population density,group richness,diversity index and evenness,the community structure and its seasonal changes were described.There were 12 groups of soil micro-arthropodes in this region,and of the groups,Collembola and Acarina were dominant,and Diptera,Coleoptera and Hymenoptera were often seen in fallow,forest and upland field,while Collembola,Acarina and Diptera were dominant in paddy.Both land utilization and seasonal change influenced the population density,group richness and diversity index of soil micro-arthropodes.The vertical distribution in both density and group number of arthropods in soil was in the order of surface>middle>bottom.

Key words: Soil micro-arthropod, Community structure, Bio-indicator, Land utilization, Lower Reaches of Liaohe Plain
