武威市北部典型荒漠植物群落物种组成及多样性特征分析
Analysis of Species Composition and Diversity Characteristics of Typical Desert Plant Communities in the Northern Region of Wuwei City
摘要
Abstract
This study analyzed the structure and species diversity characteristics of typical plant com-munities in the northern region of Wuwei City by measuring the species composition,structure,and growth indicators of the typical desert vegetation communities.The results showed that:(1)The typical desert plant communities in the northern region of Wuwei exhibited a simple structure with scarce species composition,fully reflecting the characteristics of desert vegetation communities.(2)The typical desert plant communities in the northern region of Wuwei consisted of shrub/semi-shrub layers and herbaceous layers,with shrub species and perennial herbaceous species present.(3)The species diversity level in the typical desert plant communities was low.(4)Habitat conditions deter-mined the species composition and biodiversity characteristics of the communities.Communities domi-nated by saltbush(Kalidium foliatum)and wormwood(Artemisia desertorum)had poor habitat con-ditions,resulting in fewer species and higher diversity indices.In contrast,communities represented by red sand-verbena(Reaumuria soongorica)on gravel gobi had richer species composition and high-er diversity indices.Therefore,habitat conditions play a decisive role in determining the species com-position and quantitative characteristics of plant communities.关键词
