摘要/Abstract

摘要：

羊草群系在我国温性草原区分布较广, 是畜牧业利用价值最高的草原植被类型。调查羊草群系的分布、群落特征可为天然草地管理和恢复提供数据资料。该研究利用在内蒙古调查的46个样地的数据, 对区域内羊草群系的物种组成、生态特征和群落分类进行了详细描述和分析。共记录到维管植物187种, 隶属于37科109属, 包含物种最多的科为菊科, 物种最多的属为蒿属(Artemisia)。生活型以多年生草本植物为主, 占71.66%; 水分生态类型以旱生植物为主, 占67.38%; 区系地理成分以东古北极分布种最多, 其次是亚洲中部分布种。调查到的羊草群系可划分为羊草-丛生禾草、羊草-半灌木、羊草-根茎型禾草、羊草-薹草类、羊草-一、二年生草本、灌丛化羊草、羊草-鳞茎型草本和羊草-杂类草共8个群丛组, 26个群丛。

Abstract:

Leymus chinensis alliance, one of the most widely distributed communities in China’s temperate steppe, is a grassland vegetation type with the highest utilization value for animal husbandry. Investigating the distribution and community characteristics of Leymus chinensis formations can provide data for the management and restoration of natural grasslands. In this study, we investigated the characteristics of L. chinensis communities of 46 sites in Nei Mongol, including species composition, ecological characteristics, and community classification of L. chinensis alliance. A total of 187 vascular species, belonging to 109 genera and 37 families, were recorded. Asteraceae was the family with the most species, while Artemisia was the genus with the most species. Perennial herbs were the dominant life form, accounting for 71.66% of the total species. Xerophyte dominated the communities, accounting for 67.38% of the total species. The geographic composition of the system was dominated by the Eastern Palearctic species, followed by the Central Asian species. The L. chinensis alliance could be divided into 8 association groups, including Leymus chinensis - tussock, Leymus chinensis - semi-shrubby, Leymus chinensis - rhizome, Leymus chinensis - Carex, Leymus chinensis - annual/biennial, Shrub - Leymus chinensis, Leymus chinensis - bulbiferous herb and Leymus chinensis - forb and 26 associations.
