摘要
本研究通过查阅植物志和标本,获取了中国鹿蹄草属(Pyrola)的地理分布信息.结果显示:(1)我国所有省份皆有鹿蹄草属分布,其中吉林省和四川省分布最多,达到了10种;(2)鹿蹄草属为北温带分布型,但种一级以中国特有分布型最多;(3)从海平面以上至海拔4 100 m皆有鹿蹄草属分布,主要集中分布于海拔1 500～2 500 m;(4)我国鹿蹄草属分布区与针叶林高度重叠,最多见于寒温性针叶林,具有植被恢复的指示意义.
Abstract
This study presents comprehensive data on the geographical distribution of the genus Pyrola across China,gathered through extensive literature review and specimen analysis.Results showed that:(1)Pyrola is ubiquitously distributed throughout all Chinese provinces,with Jilin and Sichuan recording the highest species counts,each hosting 10 species.(2)The Pyrola genus exhibits a predominant north temperate distribution type,but at the species level,the Chinese endemic distribution type is most common.(3)The altitudinal range of Pyrola spans from sea level to 4 100 m,primarily between 1 500-2 500 m.(4)There is a significant overlap between Pyrola distribution areas and coniferous forests in China,predominantly within boreal coniferous forests,indicating their significance for vegetation restoration.
