The land w as div ided into 4 types in both places, and 2~ 6 quadrats w ere placed in everykinds of area types. Then arbor layer ( 20 m × 20 m) , shrub layer ( 3 m × 3m ) and herbage layer ( 3 m × 3 m)w ere investigated separate ly. By means o f spec ies importance value, species diversity, n iche et al. , the eco log icalcharacter istics of vegetation in limestone mounta in were stud ied actually. Accord ing to comparison o f the data in2001 and 2005, w hich stand for the vegeta tion actuality under jamm ing and natural restorat
