【Abstract】 The survey and study on the vegetation in the area of collapsing erosion in south of Jiangxi showed that:The vegetation of the severe erosion areas is a piece of secondary vegetation that mainly consists of mesic or xeric-mesic perennial herb. The floristic composition of plant community is very simple and the stratification and structure are uniform with a low coverage. The classification of the vegetation is studied with the numerical method of Group Averaging Analysis. The vegetation of the severely eroded red soil are divided into 5 main community types. The result is very similar to those of the quantitative classification, which demonstrates that the method of quantitative classification is suitable for the classification of the vegetation of the severely eroded red soil. The typical herb communities in existence and its habitat obviously have secondary, xeromorphic and degraded traits. The existing dominant plant communities are secondary ones relatively stable after degradation.更多还原
