Abstract：Based on the survey in 32 plots in Baotianman Nature Reserve, the total 21 indices were selected to represent three types of factors including plant communities, terrain and environmentcharacteristics. Principle component analysis, cluster analysis and canonical correlation analysis were employed to study the relationships among three types of factors. Principle component analysis showed hat the elevation and soil thickness can be used as sensitive indices to describe plant change. Cluster analysis indicated that with the arising of elevation, the soil thickness increased，the soil water content decreased, arbor species increased, and shrub and herb species decreased. Results of canonical correlation analysis expressed that there were significant correlations between terrain and community indices, and between environment and community indices, whereas，the relationship between terrain and environment indices were not significant. It can be concluded that the arbor species and stand density could reflect the terrain and soil change well.
