Research on Forest Community Structure of Quercus Aquifolioides under Different Disturbance Types in Sejila Mountain
Disturbance on forest community structure has a direct impact.It is an obvious difference that Characteristics of community structure of forest under different disturbance types and intensities.It is studied that Quercus aquifolioides communities of Sejila mountain spreading widely distributed in the nyingchi area in this paper.The present paper is aimed to study the characteristics of community structure of Quercus aquifolioides under selecting fire,logging,grazing,undisturbed sample type several conditions.The results showed that the community of species richness index,shade aensity and shrub and herb cover,biodiversity indicators were a big difference under different disturbance types of communities.Non-interference condition index was generally higher than that under interference conditions,and the ground total species richness and herbal layer diversity indices under grazing traces were much larger than that in the three community types,mainly due to grazing control of dominant species in the community and increasing community species diversity.
