摘　　要：为给广宁红花油茶人工林改造与新造提供理论和技术指导,采用样方调查的方法,测定分析了广东云浮南山森林公园35年生广宁红花油茶人工纯林林分特征。结果表明:该林分平均胸径为8.7 cm,平均树高为6.0 m,平均冠幅面积为9.70 m2,林分平均密度为2 313株/hm2;林分胸径分布近似于正态分布;林分树高和冠幅面积均随胸径的增大而增大;林分密度越大,其冠幅面积越小;该林分郁闭度0.9以上,萌芽更新力强,年龄结构复杂,但林下植物组成单一,种类较少,盖度在1%左右。In order to provide some theoretical and technological guidance for reformation and building of Camellia semiserrata plantation, forest stand characteristics of 35-years C. semiserrata plantation in Yunfu Nanshan Forest Park of Guangdong Province were investigated and analyzed by the method of plot investigation. The results show that average diameter at breast height （DBH） of the forest stand is 8.7 cm, average tree height is 6.0 m, average crown size is 9.70 m2, and average stand density is about 2 313 plants per hm2. DBH distribution of the forest stand is similar to normal distribution. Crown size and tree height of the forest stand increase with DBH increasing. The greater stand density, and the less crown size. The forest stand, crown density of which is above 0.9, has strong sprouting ability and complicated age structure, however, derground composition is simple, the types are few, and cover degree is about 1%.
