| 摘 要： | 利用单木竞争指数模型 ,研究富口和黄坑乳源木莲种内和种间的竞争强度的大小 ,结果表明 :间伐时间的不同 ,对乳源木莲种内与种间竞争强度影响很大 ,富口和黄坑种间竞争均大于种内竞争 ,但黄坑的乳源木莲种内和种间的竞争强度均大于富口 .竞争指数与对象木胸径符合幂函数关系 ,并达到显著水平 ,乳源木莲种内、种间及整个林分的竞争强度随着对象木胸径的增大而下降 ,并维持在较低的水平

| Abstract: | Used the model of mono tree competition index,the inner species competition and inter species competition of Manglietia yuyuanensis in Fukou and Huangkeng were analysed.The results show that there is serious influence on the competition degree of Manglietia yuyuanensis with the different time of woodcutting.The inner competition is more serious than inter competition in Fukou and Huangkeng and the competition degree of these of Huangkeng is more than Fukou.It is power function between the competition index and objective trees.With the increase of objective trees′chest diameter,the competition intensity of species and forest will descend and may be in the low level for a long time. |
