摘 要：
以辽西北不同草原区黄背草+羊草、羊草+羊胡苔草+百里香、野古草+荆条和隐子草+狗尾草+杂草类群落4种典型群落为研究对象,分析不同植物群落的特征和土壤特性。结果表明,隐子草+狗尾草+杂草类群落在植被特征和土壤特性上均显著差于其他3种草原典型植被群落。因此,隐子草+狗尾草+杂草类植被群落应予以重点保护,实施全面禁牧促进植物群落稳定,提高群落特征值和土壤肥力。

摘 要：
In order to expolre the plant community and soil characteristics of different steppe region,four typical vegetation communities,the Themeda triandra var. japonica-Leymus chinensis community,Leymus chinensis-Carex callitrichos-Thymus mongolicus Ronn community,Arundinella anomala-Vitex negundo L. var. heterophylla community,Cleistogenes squarrosa(Trin.) Keng-Setaria viridis(L.) Beauv.-weeds community were investigated. The result showed that the plant and soil characteristics of the Cleistogenes squarrosa(Trin.) Keng-Setaria viridis(L.) Beauv.-weeds community were both significant lower than the other three typical vegetation communities.Therefore,the Cleistogenes squarrosa(Trin.) Keng-Setaria viridis(L.) Beauv.-weeds communities in northwestern Liaoning steppe should be focused on protection and implementing complete graze-prohibiting,in order to promote the community stabilities,improve community eigenvalues and soil fertilities.
