Abstract: This paper studied the species composition and the structure and species diversity of communities in Hongchiba area of Wuxi County after controlled burning and aerial sowing afforestation.The results showed that after burning and afforestation,pure Pinus armandii forest was not developed,but various mixed needle board-leaved forests which comprised P.armandii and native board-leaved trees grew.Various native species contributed to the communities with great species diversity.Shannon-Wiener index was 2.305~3.145,ecological dominance was 0.063~0.151,and evenness was 0.600~0.749 The natural regeneration of P.armandii population was very poor,and there was a trend that P.armandii would be gradually replaced by other native board-leaved trees.It was demonstrated that P.armandii should not be taken as a unique afforest tree,and controlled burning was not a favorite ecological measure in subtropical area.Native trees should play more important roles in the process of ecological restoration.

Key words: Hongchiba/Wuxi county, Aerial-sowing afforestation, Controlled burning, Ecological restoration, Species diversity, Pinus armandii
