The results showed that Liquidamba formosana, Quercus acutissima, and Quercus fabri populations had the dominant positions in the forest community of Purple Mountain Area of Nanjing. During the growth process, the mortality of L. formosana, Q. acutissima, and Q. fabri were higher in low age. After entering into the middle-age stage, the upper space was occupied by oak and L. formosana population all died. The mortality of Q. acutissima and Q. fabri populations were increased with the increasing of diameter class. L. formosana population in the Purple Mountain Area of Nanjing belonged to be the typical growing population and Q. acutissima population was a decreasing population. Q. fabri population belonged to be the growing population on the whole, but the diameter class in middle parts was incomplete and the population was difficult to be renewed. Among the studied quadrate, only one dominant population showed an aggregated distribution and other dominant species showed the random distribution. Either, all the dominant species in all the quadrates presented random distribution.

结果表明，枫香种群、麻栎种群和白栎种群在南京紫金山地区森林群落中占有优势地位；枫香种群、麻栎种群和白栎种群在其生长过程中，在低龄时期，死亡率都较高，进入中龄期后，由于上层空间都被栎木占据，枫香种群全部死亡，而麻栎种群和白栎种群的死亡率则随着径级的增大而增大；南京紫金山地区枫香种群属于典型的增长型种群，麻栎种群属于衰退型种群，白栎种群总体上属于增长型群落，但中间径级不完整，种群更新较为困难；在所研究的每一个样方中，一般只有一个优势物种呈聚集分布，而其他优势物种呈随机分布，或样方中所有优势物种都呈随机分布。
