The fixed plot was set up in this field investigation to describe the seasonal dynamics of species composition and species diversity of the communities in Wenzhou City invaded by Solidago canadensis. The results showed that the species number in January and October were less than those in April and in July. The species of communities changed with seasonal variations. Most of the species existed transitorily in the community, with the top three species showing the vertical structure of certain niche difference. The dominant species also changed with seasonal variations. In two plots of Nanbao, Solidago canadensis was the dominant species or subdominant species (except October, due to human interference), showing that it had been in the stage of successful invasion. In three plots of Yangfushan, the important values ??of Solidago canadensis rised with seasonal variations, showing that it had been in the early settled stage of invasion beginning period.
