| Summary: | [Objective] Investigating and analyzing the structure and dynamics of Fagaceae community in
the subtropical evergreen broad-leaved forest of Malipo is important for exploring the coexistence mechanism
and dominance of Quercus, Lithocarpus, and Castanopsis. This study provided an empirical study
for understanding Fagaceae coexistence. [Methods] We set four 600 m2 plots in the Malipo natural reserve
in May 2021. Excel 2019 and SPSS 25.0 software were used to analyze the dominant group by both individual
number and basal area, and make static life table and survival curve to understand the differentiation
among different genera and their coexistence mechanisms. [Results] (1) The average basal area of Fagaceae
and Lithocarpus were 57.04% and 32.82%, which made them the dominant family and genera, respectively.
(2) The diameter class distribution of the three genera was all barrel-shaped, with small proportion
of seedlings and large trees (17.43%) and large proportion of small- and middle-sized trees (82.57%). (3)
The survival curves of the three genera all fitted the Deevey-Ⅱ type. The mortality of Quercus and Castanopsis
species was increased with increasing in diameter class, whereas after becoming saplings, Lithocarpus species
become stablized. [Conclusion] Fagaceae, especially Lithocarpus, is the dominant group in the evergreen
broad-leaved forests of Malipo. The differentiation in community dynamics, species distribution,
and diversity among these three genera are important reasons for their coexistence and dominance. |
