中文摘要	采用4种多样性指数对阿拉善高原7个珍珠猪毛菜群落进行分析,并结合气候与土壤因子进行相关性分析,探究阿拉善高原不同生境中珍珠猪毛菜群落结构、物种多样性特征及与环境因子之间相互关系。结果表明:阿拉善高原珍珠猪毛菜群落结构单一,共计11科23属27种,主要为藜科、蒺藜科和禾本科植物,植被生活型以灌木和半灌木为主,多年生草本和一年生草本植物相对较少。珍珠猪毛菜群落的物种多样性水平较低,较干旱地区的珍珠猪毛菜群落间相似性指数较高。珍珠猪毛菜群落的密度、盖度、生物量与年降水量、土壤含水量、土壤有机质和全氮含量存在显著或极显著的正相关关系(P<0.05或P<0.01),Shannon-Wiener指数、Margalef丰富度指数与土壤pH值、温度生态因子存在显著或极显著的正相关关系(P<0.05或P<0.01),Pielou均匀度指数与土壤含水量显著负相关(P<0.05)。
英文摘要	To explore the relationship among community structure,species diversity and environmental factors of Salsola passerina in different habitats of Alxa Plateau,four diversity indexes were used to analyze seven S.passerina communities in Alxa Plateau,and the correlation analysis was conducted with climate and soil factors.The result showed that the community structure of S.passerina in Alxa Plateau was single,with 27 species belonging to 23 genera and 11 families,mainly including Chenopodiaceae,Zygophyllaceae and Gramineae.The life forms of vegetation were mainly shrubs and subshrubs,while the number of perennial and annual herbs was relatively small.The species diversity of S.passerina communities was low.In the drier regions,the similarity index of S.passerina community was higher.The density,coverage,biomass of the S.passerina communities had significantly or extremely significantly positive correlation with annual precipitation,soil water content,soil organic matter and total nitrogen content.Shannon-Wiener index and Margalef richness index had significant or extremely significant positive correlation with soil pH and temperature ecological factors.Pielou evenness index had significant negative correlation with soil water content.
