Plant Species Diversity and Its Seasonal Dynamics in Woodland Invaded by Solidago canadensis (Asteraceae)
加拿大一枝黄花入侵林地对植物多样性的影响及其季节变化

The effects of invasion by Solidago canadensis on plant species diversity in semi-natural woodland were studied.Results showed that plant diversity of the woodland decreased with severe invasion by S.canadensis.No significant differences were found between the control plot and the spreading plot(where the coverage of S.canadensis was less than 40%);nevertheless,Simpson index,Shannon-Wiener index,and evenness index of the control plot and spreading plot were higher than the invaded plot(where the coverage of...
