Based on the research in 36 different sites with different pinus massoniana mixed proportion and invasion extent of Bursaphelenchus xylophilus in Fuyang,Zhejiang Province,the authors analyzed the change of community diversity of all forest types in arbor,shrub and herb layers after invaded by Bursaphelenchus xylophilus.The results showed that invasion of B.xylophilus tended to reduce the differences in diversity of arbor,shrub and herb layers in pinus massoniana community of different forest types.However,much heavier invasion of B.xylophilus resulted in a new feature in diversity indexes of all forest types,showing a trend of reciprocating between polarization and consistency.Furthermore,successional stages of community in Fuyang,Zhejiang Province were processing from early stage to middle stage of evergreen broadleaved forest;whilst the increase of composite disturbance accelerated such successional stages.
