Structure of Taxus yunnanensis in Yunling Provincial Nature Reserve

Abstract

Abstract:

In order to study the community structure of Taxus yunnanensis， the Taxus yunnanensis community in the Yunling Provincial Nature Reserve was taken as the research object. Based on the analysis of the survey data of 5 field community samples， it was found that there were 57 species of vascular plants in the community， belonging to 29 families and 48 genera. The community stratification is obvious. The dominant species in the tree stratum， shrub stratum and herb stratum are Taxus yunnanensis， Fargesia spathacea and Duchesnea indica respectively. Based on the analysis of species diversity， the Shannon-Wiener index， Simpson index and Pielou evenness index is herb stratum> tree stratum> shrub stratum. Taxus yunnanensis has sufficient seedling bank， but lacks saplings， indicating that the establishment of the reserve has a positive effect on the protection of Taxus yunnanensis， but the protection still needs to be strengthened to reduce the impact of human disturbance.

Key words:

"> Taxus yunnanensis, species diversity, age structure, threatened plant
