摘要:
为给西藏一江两河流域农区农牧业发展提供参考,在野外调查基础上,对该区域草本植物种类及其区系特征进行了研究,结果为该区域共有草本植物223种,隶属56科153属,其中菊科、毛茛科、豆科种类最多,蓼科、禾本科、十字花科、唇形科等种类也较多; 紫茉莉科、苦苣苔科、睡莲科等21科各有1属1种。草本植物属分布于12个类型8个变型,其中,北温带分布最多,有29属,占本区草本植物总属数23.2%; 世界分布、泛温带分布各有26属,各占20.8%。
Abstract:
In order to provide reference for the development of agriculture and animal husbandry in the agricultural areas of the Yarlung Zangbo River and its Two Tributaries in Tibet, the species and floristic characteristics of herbaceous plants in this region were studied on the basis of field investigation. The results showed that there were 223 species of herbaceous plants in this region, belonging to 153 genera and 56 families, among which compositae, buttercup and leguminous plants had the most species, followed by plants from polygonaceae, gramineae, cruciferae and labiaceae. There are one genus and one species in each of 21 families, including ambrosia, gesneriaceae and nymphaeaceae. The herbaceous genera were distributed in 12 types and 8 variations, among which, 29 genera were most distributed in the north temperate zone, accounting for 23.2% of the total herbaceous genera. There are 26 genera with worldwide distribution and pan-temperate distribution accounting for 20.8%.
