摘要
本文针对内蒙古天然草地植被地带性分布的规律,测定草原区各亚型主要群落地下生物量与组成该群落建群种或优势种根系特点的相关性,从而探讨各群落地下生物量之间的差异性。
Based on the zonal distribution of vegetation in rangeiand of Inner Mongolia, underground biomasses of plant communities and root characteristics of edificato and dominant species in main plant communities of various subtypes of steppe region were studied, in order to probe variantion of underground biomass among various plant communities.
