入侵

There were 14 invasive alien plant species out of 53 investigated plant species, accounted for 26.42% of total plant species found in the experimental zone. In terms of the comprehensive values of dominance of invasive alien weeds, Ageratum conyzoides and Pliea microphylla were larger than that of other plant species.
