摘　　要：食细菌线虫是土壤线虫主要的营养类群之一,其与细菌通过捕食关系构成的网状结构是土壤微食物网中最为重要的一部分,对食物网中的能流方向和大小起关键的控制作用。本文概述了食细菌线虫对细菌数量和群落结构的影响,食细菌线虫与细菌捕食与被捕食的动态平衡关系,及主要环境因子(土壤水分、温度、含氧量、C/N和p H)对食细菌线虫和细菌群落结构的影响,以期为深入揭示土壤食物网的功能和机制及土壤的生态过程提供理论依据。Bacterivores is an important trophic group of soil nematodes. The web structure,formed via prey of bacterivores on bacteria,is one of the most important parts in soil microbial food web,which plays a key role in energy flow direction and size in soil food web. In this paper,we reviewed influences of bacterivores on bacteria population and community structure,described the dynamic balance between bacterivores and bacteria,and finally summarized the effects of major environment factors（ soil moisture,soil temperature,soil oxygen content,soil C/N and p H） on community structure of bacterivores and bacteria. This review would benefit to the discovery of function and mechanism of soil food web,and provide useful information for further understanding soil ecological processes.
