摘要
为深入研究西藏米拉山区植物资源的分布和多样性,对该区植物资源作了系统调查。西藏米拉山区有维管植物86科324属765种,其中蕨类植物15科20属37种,裸子植物有3科7属12种。种类组成趋向于集中在少数科内,区系优势现象明显,反映出米拉山自然环境的特殊性和区系的过渡性。根据植物的用途,将米拉山区的植物资源分为11类,并提出了该区植物资源保护和可持续利用的策略措施。
A systematic survey was conducted in the Mila mountains in Tibet.There are 86 families,324 genera and 765 species in Tracheophyta flora of Mila mountains.Among them there are 15 families,20 genera and 37 species of Pteridophyta and 3 families,7 genera and 12 species of Gymnospermae.The composition of species tending to centralize in few families and obvious advantage of region reflect the environment particularity and region transition in Mila mountians.The plant resouces in Mila mountains were divided into 11 categories according to its usefulness.Also,the strategies and measurements on the conservation and sustainable usefulness of the plant resources were put forward.
