摘 要 ：本文报告了内蒙古荒漠草原地区37种植物氮、硅与灰分含量的组成特征。结果表明，荒漠草原区植物的平均含硅量(1.019%)，灰分含量(12.85%)都高于草甸草原与典型草原，而其含氮量(2.16%)都低于草甸草原与典型草原。在内蒙古草原区，植物化学元素组成呈现了地带性分异的特征。

Abstract:The characteristics of nitrogen and ash content of 37 species of plant on desert steppe, Inner Mongolia was reported in this paper. These results show that the Si (1.019%) and ash (12.85%) contents on desert steppe are higher than on typical and meadow steppa, but its N (2.16%) content is lower than typical and meadow steppe. The determination of the content of chemical elements indicated zonal characteristics from east to west in Inner Mongolia steppe zone.
