Abstract
Indication function of Guangdong indigenous tree species to different climatic factors (mean annual temperature, rainfall and sunshine hours) was confirmed with indicator species analysis. The results showed that the climatic factors had significant influence on the distribution of indigenous tree species in the following order: mean annual temperature>mean annual sunshine hours>mean annual rainfall. Actinodaphne lecomtei, etc. were indicator species for north of Lianshan (≤19°C). Liquidambar acalycin, etc, were indicator species for Northern Guangdong's mountainous areas (≤1400 h). Adinandra megaphylla was indicator species for Yangjiang coastal regions (>2200 mm). This research provided scientific basis for indigenous broadleaves tree species selection in regional forestation.
