Abstract:
The Invasion of Bursaphelenchus xylophilus on Zhoushan island resulted in the death of Japanese black pine (Pinus thunbergii) in 1992. With a plot investigation (plot size 100 m×100 m) in Changgang Mountain, the stand structure of P. thunbergii forest was studied. The results showed that the past P. thunbergii forest now became a mixed conifer and broadleaved forest with an increasing of species richness and plant diversity. The deciduous broadleaf trees were the majority and had a relatively large advantage in the forest canopy. However, the evergreen broadleaved trees were the minority and mainly distributed in the middle and lower layer. The forest stands, lack of dominant species, was an aggregation distribution with low mixed degree. The above results showed that the forest is still in the early succession and needs a long-term process for the development of evergreen broadleaved forest. In order to speed up the forest succession and restore the local forest ecological system as soon as possible, we suggest that it is important to replant some island zonal vegetation selected from the native tree species.
