Changes in species diversity in the succession of plant communities of abandoned land in Luliang Mountain, western Shanxi

The Detrended Correspondence Analysis (DCA) was employed to analyze the trend and direction of plant community succession of abandoned loess land. Seven species diversity indices were used to study the changes in species richness, species evenness and diversity in the succession. With the development of succession, species richness increased significantly, species evenness decreased slightly and diversity went up.
