摘要：

In this study, we investigated the composition and structure of a degraded low-elevation forest of Gukeng Farm to establish a successional pathway. Twenty-four 20 × 20-m plots were established. Forest types, based on the floristic composition of the plots, were classified using a cluster analysis (CA), two-way indicator species analysis (TWINSPAN), and tabular comparison methods. Five forest types were identified and described: Aleurites montana-Machilus zuihoensis, Euphoria longana-Mallotus paniculatus, Trema orientalis, Ficus fistulosa-Ficus septica, and Glochidion philippicum-Ficus irisana. Relationships of the major gradient axis of the detrended correspondence analysis (DCA) with both environmental and vegetation variables were calculated using Pearson correlation coefficients. The results showed that these types were interpreted as levels in a successional sequence ranging from an early-successional stage to a mid-successional stage and late-successional stage. There were 2 successional pathways. One occurred in the drier environment, i.e., ridge-type sere, which ranged from the Trema orientalis forest type, Euphoria longana-Mallotus paniculatus forest type to the Aleurites montana-Machilus zuihoensis forest type; the other was in the morehumid environment, i.e., the valley-type sere, which ranged from the Trema orientalis forest type, Ficus fistulosa-Ficus septica forest type, to the Glochidion philippicum-Ficus irisana forest type.
