Interspecific Correlations among Tree Species in the Stewartia sinensis Community in Qianjiangyuan National Park,Zhejiang Province

In order to quantitatively analyze the relationships between Stewartia sinensis and other species and provide suggestions about the protection of this rare species,interspecific relationships in the typical evergreen broad-leaved communities of Stewartia sinensis were studied based on field data from three plots of 400 m~2 in Gutianshan National Nature Reserve. All 66 tree species in the communities were selected and variance ratio( VR) analysis of the overall association,Pearson correlation coefficient test and Spearman rank correlation coefficient test were performed. In the three test methods above,the ratios of positive and negative correlations were all greater than 1,indicating that species closely interacted with each other and the structure and function of the Stewartia sinensis communities were tending toward mature. Stewartia sinensis didn't develop relationships with most of species,suggesting that Stewartia sinensis had a relative independent status in the communities. Particularly,there were nine species which were negatively related with Stewartia sinensis,including Symplocos paniculata,Sassafras tzumu,Litsea cubeba and so on. This suggested the competitive relationships between Stewartia sinensis and the nine species. Selective cutting may be required to moderate the interspecific competition and build a suitable habitats for Stewartia sinensis.
