摘　　要：披碱草属是禾本科、小麦族的一个有重要经济价值的属,其属内绝大多数种类是畜牧业上的优良牧草,饲用价值极高,有些种类具有耐寒、耐旱、耐碱等特性,是农牧业上良种繁育、牧草利用的重要基因资源;但该属同时又是分类学上的一个疑难属,其属内系统分类各学者意见不一、争议颇大,尤其在属的界限、属下类群划分、以及类群演化关系上问题较多,至今尚未解决.本研究查阅了国内外分类学文献,探讨其分类差异以及存在问题,为充分开发利用我国丰富的披碱草属植物资源提供理论依据.Elymus is a genus with important economic value In Triticeae, Most of them are excellent grasses for animal husbandry. Meanwhile, some of them have perfect characteristics in enduring cold, drought and alkali. So they are always used as important germplasm resources for grass breeding and improving breeds of crops. Despite decades of intensive efforts, there are still many unsolved questions to be answered, such as Elymus definition, species classification and evolutionary relationships. Therefore, the systematic difference and existing problems were discussed by referring to taxonomic references of home and abroad in this article. This report will provide the theoretic foundation for research and utilization of abundant plant resources of Elymus in China.
