The typ es of t he evergreen broadleaf forest and t heir community sp ecies diversity characteristics in Longqishan nature reserve were studied based on field investigation . The result s showed t hat t here were mainly 6 typ es ( Formation) of evergreen broadleaf forest in t he reserve . The richness of differ ent community layer showed shrub layer (including seedling and sapling) tree layer herb lay er . The coffeciency of variation ( %) of different community measured by richness or Shannon diver sit y index was tree layer herb layer shrub layer . In contrast to t he large differences in commu nity sp ecies diversity among different typ es of evergreen broadleaf forest , communities in different areas almost showed t he same diversity p attern of shrub layer tree layer herb layer .
