摘 要 ：划分出萨吾尔-塔尔巴哈台山地植物种一级的分布区类型共12种类型及3种亚型。分析结果表明，南北向格局分布区类型中的种类数目占总种数的三分之一多，说明本区在近代与南北植物区系的交流较多，成为南北植物区系物种交流的重要通道及由于该地的低海拔成为一些山地物种的分布边界，但中低山及平原中旱生性质的种类的分布未受到本区地形的影响.

Abstract:From the rhizomes of Rodgersia pinnata,six monoterpene disaccharide glycosides were isolated and their chemical structures were determined as (E)3,7dimethyl1O［αLrhamnopyranosyl(1→6)βDglucopyranosyl］oct2en7ol (1),(E)3,7dimethyl1O［αLarabinofuranosyl(1→6)βDglucopyranosyl］oct2en7ol (2),geranyl1OαLarabinofuranosyl(1→6)βDglucopyranoside (3),geranyl1OαLrhamnopyranosyl(1→6)βDglucopyranoside (4),geranyl1OβDxylopyranosyl(1→6)βDglucopyranoside (5),geranyl1OαLarabinopyranosyl(1→6)βDglucopyranoside (6) by spectral methods.Among them,compound 1 is a new monoterpene disaccharide glycoside.It is the first time that monoterpene disaccharide glycosides were isolated from the genus Rodgersia.
