摘要/Abstract

摘要： 为了探讨砂仁种植对热带季节雨林土壤节肢动物群落的影响,采用样地调查法对西双版纳勐仑自然保护区热带季节雨林及林下砂仁种植地土壤节肢动物群落进行了调查,2种生境、不同季节 3次取样共获得土壤节肢动物 3772个,隶属 6纲 23目,其中砂仁地中膜翅目(蚂蚁)、蜱螨目、半翅目为优势类群,占全捕获量的 73.329%,而季节雨林中膜翅目(蚁类)、蜱螨目、鞘翅目和弹尾目为优势类群,占全捕量 89.778%。 2样地土壤节肢动物类群数、个体数和多样性指数的水平分布差异显示为季节雨林高于砂仁地,垂直分布显示季节雨林为土壤表层多于下层,表聚现象明显,砂仁地因受人为活动影响,其土壤节肢动物的垂直分布具有较大变化,出现下层高于表层的逆向分布 ;2样地土壤节肢动物群落季节变化趋势相近,均表现为干季高于雨季,其中砂仁地土壤节肢动物个体数在干热季最多,季节雨林个体数则在雾凉季最高.

Abstract: In order to investigate the effect of planting Amomum on soil arthropod communities in tropical seasonal rain forest in Xishuangbanna, the investigation method in the sampling plots was used to study soil arthropod communities in tropical seasonal rain forest and Amomum plantation in 1999. The results showed that total numbers of soil arthropods were 3772 which consisted of 6 classes, and 23 orders in two plots. Ants, acari, hemiptera were dominant groups in the Amomum plantation, the proportion of total individuals of three groups in soil arthropods communities of Amomum plantation was 73.329%. Ant, acari, coleoptera and collembola were dominant groups in tropical seasonal rain forest and their proportion of total individual in soil arthropod communities was 89.778%. The numbers of individual and diversity of soil arthropod communities were higher than those in the Amomum plantation. The vertical distribution of soil arthropod communities in the Amomum plantation was disturbed by human activities, the groups and individuals of soil arthropod in under layer of soil(10～15cm)were more than those in surface layer of soil(0～5cm). In general, groups, and individuals of soil arthropod communities of two plots were higher in dry season than those in metaphase of rainy season. But there were some differences on the seasonal change of soil arthropod individuals in the two plots.
