| 摘 要： | 以黄河兰州段分布最广泛的芦苇-假苇拂子茅群落和酸模叶蓼-灰绿藜群落为研究对象,研究2个群落的植物物种组成和多样性特征。结果表明:芦苇群落有植物22种,隶属于13科20属,酸模叶蓼群落有植物24种,隶属于11科22属,2个群落的共种有10种,相似性系数为43.48%,菊科、禾本科、藜科、蓼科是该植物区系的优势科。物种多样性的分析说明2个群落的Pielou指数(J)波动比较小,Simpson指数(D)和Shannon-Wiener指数(H)均波动都比较大,并且H指数与J指数存在明显的正比例关系,而与D指数呈显著的反比例关系。方差分析表现出两群落S,H,D和J指数的差异并不明显,说明组成两群落的物种有一定的相似性和连续性,也存在着差异。

| Abstract: | The typical plant communities (Phragmites australis-Calamagrostis pseudophragmites and Po-lygonum lapathifolium-Chenopodium glaucum )along Yellow River in Lanzhou were selected to investigate the plant species and composition characteristics.The results indicated that there are 22 species in Phragmites aust-ralis-Calamagrostis pseudophragmites community,which belongs to 13 families and 20 genera,and 24 species in Polygonum lapathifolium-Chenopodium glaucum community,which belongs to 1 1 families and 22 genera.To-tally 10 common species were found in 2 communities.The similarity coefficient between 2 communities was 43.48%,Asteraceae,Poaceae,Chenopodiaceae and Cyperaceae were the dominant families.Species diversity analysis showed that in 2 communities,Shannon-Wiener index(H)and Simpson index(D)varied greatly,while Pielou index (J)showed much less variation.The diversity index was positively correlated with the evenness in-dex and negatively correlated with the ecological dominance index.H,D,J and S values were not significantly different in 2 communities. |
