The study analyzed the species composition and community structure of a secondary forest in the Qinling Mountains, finding 3162 individual woody plants across 42 species, dominated by temperate tree species.
Key tree species held a significant importance value, accounting for 64.7% of the community, while the average diameter at breast height (DBH) of all woody plants was 7.58 cm.
The community structure showed stability but poor renewal, with biodiversity indices lower than subtropical evergreen forests and notable correlations between species distribution and environmental factors like soil and altitude.
