以内蒙古荒漠区短脚锦鸡儿灌木为研究对象,采用野外调查法分析灌丛对植物群落的影响,采用传统培养法,结合分子鉴定法分析灌丛对土壤微生物群落的影响。结果表明：（1） 灌丛内植物群落多度和总生物量显著大于灌丛外,但是物种丰度和Shannon-Wiener指数灌丛内外无显著差异;（2） 随土壤深度的增加,表层土与深层土的土壤可培养细菌丰度和真菌多度差异不显著,其余土壤微生物群落多样性特征均表现为：表层土显著大于深层土;（3） 灌丛对土壤微生物群落具有正效应,且表层土正效应最大;（4） 灌丛对植物群落的促进作用大于对土壤微生物群落的作用。

In this study, we used Caragana breviflora in the Inner Mongolia desert area as target shrubs and field investigation methods to evaluate the effect of shrubs on plant communities, while also using a combination of traditional cultivation methods and molecular biology technology to evaluate the effects of shrubs on soil microbial communities. The findings revealed that: (1) Both the abundance and biomass of herbaceous plants were significantly greater under C. breviflora shrub canopies than in open areas, whereas there was no significant difference in the richness and Shannon-Wiener diversity index between shrub canopies and open areas; (2) The richness, abundance, and Shannon-Wiener index of soil culturable bacteria, fungi, and actinomycetes tended to be highest at either the top or subsurface soil layers; (3) C. breviflora shrubs had positive effects on soil microbial communities, and these positive effects were the highest at the top soil layer; (4) C. breviflora shrubs had more positive effects on plant communities than on soil microbial communities.
