梵净山典型固定样地草本植物调查与分析

Investigation and analysis of herbaceous plants in typical fixed sample plots around Mount Fanjing

对梵净山10个典型固定样地的草本植物进行了实地调查。共记录草本植物64科131属223种,其中,蕨类植物21科40属87种,被子植物43科91属136种。分析表明:草本植物在梵净山森林群落中有很高的重要性;不同海拔梯度、生境特点和森林类型的样地中草本植物分布差异性较大,组成复杂,但有一定的规律性。珍稀和受保护草本植物较多,应加强保护;可开发利用草本植物资源丰富,应作进一步研究。

A herbaceous plant survey of the ten typical fixed sample plots around Mount Fanjing was conducted.The results showed that there were 223 species of herbaceous plants,belonging to 131 genera and 64 families,of which 87 species(40 genera and 21 families)were ferns,and 136 species(91 genera and 43 families)were angiosperms.The analysis reveals that herbaceous plants are of high importance in the forest community around Mount Fanjing.In sample plots of different altitudes,habitat traits and forest types,the distribution differences of herbaceous plants are high,and the community composition is complex,but there is a certain regularity.There are many protected and rare herb species,and the protection should be strengthened.There are rich herb resources that can be utilized,which should be further studied.
