摘　　要：本文用PCA法对建立10年的人工羊草草地进行了群落排序,并结合土壤养分含量进行了相关分析。结果表明,羊草(Aneurolepidium chinense)、黄蒿(Artemisia scoparia)、大籽蒿(Artemisia sieversiana)是形成群落分异的主要植物种群。整片草地可划分为纯羊草、羊草+大籽蒿和羊草+黄蒿群落;大籽蒿+羊草群落;黄蒿+羊草群落三个群落类型及羊草与大籽蒿混生,羊草与黄蒿混生的两个过渡群落类型。土壤养分含量分布不均是造成植物群落分化的原因之一,其中K、Zn、Mg、Mn、有机质、全磷及Fe/Mn值含量为主要因子。羊草种群的分布与土壤K、Fe、Zn、有机质、Fe/Mn含量呈正相关,与土壤Ca、Mg、Mn含量呈负相关。黄蒿种群分布与土壤Ca、Mg、Fe、全磷含量呈正相关,与土壤K、有机质含量呈负相关。大籽蒿种群分布与土壤Mn含量呈正相关,与土壤Mg、全磷含量呈负相关。In this paper,the community type in artificial grassland of Aneurolepidium chinetws were divided by PCA method. At same time, the relationship between community types and nutriment factor of soil were studies. The resalts are as follows: 1. A. chinense,Artemisia scoparia, A. sieversiana are the main population dividing community. 2. The grassland can be classified three community types and two community of tranistion types, they are community of A. chinense,community of A. scoparia + A. chinense,community of A. sieversiana + A. chinense, and community of mixed A. chinense and A. scoparia, community of mixed A. chinense and A. sieversiana. 3. The distribution of nutriment of soil content is a reason for influencing distribution of plant community. The K, Zn,Mg,Mn, totalp,Fe/Mn of soil content are the main factor in nutriment of soil. 4. A positive relationship between distribution of A. chinense and K, Fe, Zn, Fe/Mn, in soil. A negative relationship between distribution of A. chinense and Ca, Mg, Mn, in soil. 5. A positive relationship between distribution of A. scoparia and Ca, Mg, Fe, totalp, in soil. A negative relationship between distribution of A. scoparia and K, organic in soil. 6. A positive relationship between distribution of A. sieversiana and Mn, in soil. A negative relationship between distribution of A. sieversiana and Mg, totalp,in soil.
