漳州市区不同植被下土壤动物群落组成及多样性研究

Study on the Composition and Diversity of Soil Animal Community in Zhangzhou City

对漳州师范学院校园内芒果树(乔木)、铁树(小乔木)、红桑(灌木)和草地四种不同植被下的土壤动物的组成、数量及多样性进行研究,共获得土壤动物631只,隶属于3门22类.其中以弹尾目和寄螨目为优势类群,占所捕获土壤动物数量的74.96%;真螨目、毛马陆目、双尾目、双翅目、同翅目和膜翅目为常见类群,其余类群均为稀有类群.另外,本研究还对各样地下土壤动物的多样性进行了分析,结果表明4个样地中土壤动物的多样性指数H'和均匀度指数J大小顺序为:芒果﹥草地﹥红桑﹥铁树,优势度指数C的大小顺序为:铁树﹥红桑﹥草地﹥芒果.

The composition,number and diversity of the soil animal community under four different vegetations of mango trees,truf,red mulberry and cycas in campus of Zhangzhou Normal University were investigated.Separated through tullgren in lab,a total of 631 soil animals were collected,belonging to 3 phylums and 22 kinds.The dominant groups were Collembola and Parasiformes,accounting for the number soil animals captured 74.96%.Acariformes,Polyxenida,Diplura,Diptera,Homoptera and Hymenoptera were the ordinary groups and others were rear groups.In addition,the diversity of soil animals under all plots were analysed.The results showed that the sequence of the diversity index H＇ and evenness index J in four plots were mango 〉turf 〉red mulberry 〉cycas,the dominance index was cycas 〉red mulberry 〉turf 〉mango.
