5. Conclusions
Our study found that at a broad landscape scale, the distribution of
regenerated individuals in the D. pectinatum community is related
to differences in climatic conditions. Variation in precipitation and
temperature due to latitude, longitude and elevation is the dominant
cause for the formation of the regeneration dynamic pattern along
distinct environmental axes, and the intermediate environmental
conditions in the mid-elevation area contribute to regeneration. At the
community level, habitat preferences related to elevational factors, TN,
AP and forest gaps play a key role in regeneration success. In addition,
biological mechanisms (negative density-limiting effects) also have a
particularly important effect on the regeneration of the community.
