Abstract: The vegetation in Dagang Mountain,Jiangxi Province was investigated using the method of quadrate and plotless sampling.Main types of vegetation can be classified as tollows:evergreenchinkapin and phoebe forest;theropencedrymion; bamboo and broadleaf mixed forest;Chinese fir plantation;montane meadow.Main forest stands in that area are Chinese fir plantation and moso bamboo forest,however, the primary zonal community,such as evergreen broadleaf forest,has remained to be secondary woods in declining odd pieces.Two new concepts have been introduced for the division of the forest condition:1.naturality──the distance from vegetation site to the virgin climax community i.e.the stage of successive process for secondary natural community under human disturbance or the proportion of natural components for artificial and semiartificial community which is divided into 5 classes in total.2.managerial intensivity——the intensive level of management of natural and artificial communities which shows the degree of effect due to managing behavior(5l evels in total).Combining with relevant maps, the evaluation has been made in 2 forestfarms by naturality and managerial intensivity.32.26% of the total area is well-managed,but 1/4 of the total forest is poorer.The natural forest accounts for 35.99%of the total beloging to the forest of low managerial intensity level(=2).
