摘要：白刺(Nitraria tangutorum Bobr.)和油蒿(Artemisia ordosica Krasch)是乌兰布和沙漠东北部人工绿洲边缘常见的植物种,从植物群落及个体特征对此2种天然植被进行研究,结果表明:白刺群落和油蒿群落结构都比较简单,白刺群落环境优于油蒿群落;白刺的地上生物量显著高于油蒿(P<0.05),两者的基径、高度和冠幅之间没有显著差异(P>0.05);白刺的地上生物量与基径、高度之间存在显著的正相关性,而油蒿的各生长指标之间没有显著的相关性。
The study was conducted on Nitraria tangutorum Bobr. and Artemisia ordosica Krasch which are the common natural plants in the artificial oasis edge of the northeast Ulanbuh desert based on the plant community and individual characteristics. The results showed that Nitraria tangutorum and Artemisia ordosica community structurs are relatively simple,the Nitraria tangutorum community environment is better than that of Artemisia ordosica. The aboveground biomass of Nitraria tangutorum is significantly higher than Artemisia ordosica（ P〈0. 05）,the discrepancy of branch diameter,height and crown between two plants has no significant difference（ P〉0. 05）. There is significant positive correlation between aboveground biomass,height and crown of Nitraria tangutorum,while there is no significant correlation among the growth indexes of Artemisia ordosica.
