In China the studies on carabid beetles were mainly focused on taxonomy, faunology and the community diversity, few reports about carabid beetles as bioindicators. Therefore, it is necessary to understand the relationship between carabid beetles and nvironment, and further explore the technique of carabid beetles as bioindicators, which might be applied to monitoring and evaluation of environment. In this paper the recent researches on carabid beetles as bioindicators are reviewed, including the advantages of carabid beetles as ioindicators, the effects of the environment factors on carabid beetles and carabid beetles' response to environmental changes.
