Abstract:

Located in the subtropical zone of China, Gutianshan National Nature Reserve (GNNR) contains a variety of forest community types and is rugged in terrain. Here, we established 79 forest plots, each 20 m × 20 m in area, within the ten main community types of GNNR. Based on this, we analyzed the α- (Shannon- Wiener index) and β- (Horn-Morisita dissimilarity index) diversity patterns of and between these community types and their underlying driving factors. We found that: (1) Community type, elevation and aspect were the most important determinants of α-diversity. α-diversity showed significant differences between community types, and increased with elevation and northness. (2) Community type and elevation, but not spatial distance significantly affected β-diversity. β-diversity between community types was higher than within community type, and β-diversity also increased with increasing elevation. These results show that community type and elevation are the main influencing factors of the α- and β-diversity patterns in GNNR forests, and further suggest the importance of drivers, such as habitat filtering, on the assembly of GNNR forests.
