本文以数值分类方法,初步确定了暗紫贝母分布的植物群落类型及其群落特征,并研究了其群落类型与松贝(川贝母)品质之间的相关性。指出绣线菊+金露梅-珠芽蓼群落、窄叶鲜卑花+环腺柳+毛蕊杜鹃群落、委陵菜十条叶银莲花群落所产松贝为品质最优的商品规格。 In this paper, the numerical classification method was used to preliminarily determine the type of plant community and its community characteristics in the distribution of Fritillaria sinensis, and to study the correlation between its community type and the quality of S. fritus (Fritillaria Fritillaria). It was pointed out that the Spiraea + Calendula-Pollenum acerifolia community, the narrow-leaved Xianbei flower + ring gland salix + mauritania aconite community and Potentilla ten anemone community were produced as the best quality product specifications.
