摘要:Abstract: Sample plots were set in Baili River village of Guandu town Zhushan county to research quantitative characteristics and structural characteristics of natural population of Phoebe zhennan S. Lee by using field survey methods. The results showed that the individual distributions of natural population of Machilus ichangensis Rehd. et Wils. and Phoebe neurantha (Hemsl.) Gamble were contagious one in survey area with a considerable density. The number of Machilus ichangensis Rehd. et Wils. in the third lever (42%) was larger than that of others. And the number of juvenile phase (33%) was also larger. So the natural population of Machilus ichangensis Rehd. et Wils. was growth. Although there was lack of the juvenile phase of Phoebe neurantha (Hemsl.) Gamble, but the third lever (83%) was very lager, and it was a stable form.
