摘  要:
大气CO2 浓度增高会对生态系统产生一系列的影响 ,这些影响在某种程度上受到土壤动物区系的调节 .本文通过论述大气CO2 浓度增高对不同类型土壤中和不同生态系统中土壤线虫产生的影响 ,阐明了用土壤线虫作为指示生物来研究生态系统变化的意义 .并提出了今后针对大气CO2 浓度增高这一现象应着重围绕土壤线虫及土壤动物区系优先开展的几方面研究 ,从而更好地指示整个生态系统的变化情况 ,为有效地管理农田生态系统提供依据 .

摘  要:
The elevated atmospheric CO 2 can make effects on the ecosystem, these effects will be mediated by the soil fauna. In this paper,we firstly discussed the response of the soil nematodes to the elevated atmospheric CO 2 in different soil pattern and in different ecosystems. Some evidences indicate that soil fauna of the detritus food webs appear to show positive, neutral or negative responses to the atmospheric CO 2 enrichment across different studies. The research prospect in the future was put forward.This paper can help us understand some ecological processes of farmland ecosystems according to the effect of elevated CO 2 on soil nematodes and provide the foundation for managing farmland ecosystems effectively.
