The study analyzed how different stand densities and climate factors influence the radial growth of trees in a secondary forest using tree ring data.
Results indicated that lower stand density led to greater average radial growth (3.12 mm) compared to medium and high densities (1.55, 1.42, and 0.96 mm, respectively).
Thinning was found to positively impact medium-density forests, while the negative effects of climate variability, particularly precipitation in January and February, were reduced by thinning, suggesting it could help counteract climate change impacts.
Maintaining forest structural diversity helps ensure forest stability and biodiversity, particularly in a primary mixed broadleaved Korean pine forest studied in eastern Liaoning.
The study found that the diameter distribution of trees followed an inverse J-shape, signaling good understory regeneration alongside larger trees.
Main trees were randomly distributed, with an optimal mix allowing for resource use and supporting both small-diameter and dominant canopy trees in the community.
