摘  要：
通过对乌兰布和沙漠白刺群落与沙蒿群落进行固定样方监测,分析白刺与沙蒿群落多样性的变化及其对降水的响应。结果表明:2个典型灌木群落物种数对降水响应明显;白刺群落与沙蒿群落中1年生草本对降水响应明显,而灌木与多年生草本对降水无响应;白刺与沙蒿群落的物种丰富度与多样性对降水响应明显,沙蒿群落与白刺群落的相似性对降水响应明显;降水量与2个典型灌木群落的物种数、盖度、丰富度指数、均匀度指数、多样性指数均呈正相关关系,相关系数均大于0.600 0。

摘  要：
The Nitraria tangutorum Bobr community,Artemisia sphaerocephala community in Ulanbuh desert were fixed for sample monitoring,and analyzing the change of the Nitraria tangutorum Bobr community and Artemisia sphaerocephala community diversity and its response to precipitation.The results showed that species number of response to precipitation was obvious; annual herb of Nitraria tangutorum Bobr community and Artemisia sphaerocephala community response to precipitation was obvious,and shrubs and perennial herbs of precipitation with no response; species richness and species diversity of Nitraria tangutorum Bobr community and Artemisia sphaerocephala community of response to precipitation was obvious,and the similarity of Nitraria tangutorum Bobr community and Artemisia sphaerocephala community of response to precipitation was obvious; precipitation was positively related with structure and diversity of the two typical shrub community,and correlation coefficients were all greater than 0.600 0.
