Soil protozoan is t he t hird largest taxon in soil biota and an important biological regulator for soil organisms and biochemical activities because of it s biodiversity predacity and enormous biomass in soil. Different trop hic typ es such as p hotosynt hetic autrop h , saprotrop h and predacity existed in protozoan . Since predation not only controls t he bacteria community but also stimulate nutrient transformation and carbon cycling , t he study on protozoan community structure and ecological function is one of t he bases for elucidating t he soil fertilit y . The article reviewed t he research pro gresses in protozoan community , trop hic t yp es , ecological function and application in soil . Key words : soil protozoan , community structure , trop hic t yp e , ecological function , protozoan application . 　　土壤原生动物是土壤微生物区系的重要组 种自生的鞭毛虫 ,有 5600 种以上寄生的孢子虫 ( ) ( 成部分 。在土壤生态系统中 , 由于微生物与微动 [包括顶复亚门 Apicomplexa 、微孢子亚门 Mi ) ( ) 物的生命活动及其相互作用 ,从而形成了土壤的
