Abstract

Plantation forest ecosystem is an important part of forest ecosystem.We use the Chinese pine which belongs to Shaanxi province Huanglong mountain as the research object and compares the four different density groups of Chinese pine plantation plots which in the difference of the spatial structure (Mingling index,Dominance index,Uniform Angle index and Crowding index) and of different shrub diversity (Simpson index,Shannon-Wiener index,Pielon index,Gleason index and Margalef index).The coupling relationship between tree spatial structure and shrub diversity was established and we discuss the relationship between them.The results showed that:(a) among the all groups,the spatial structure of the plot which showed a tree density of 2 300-2 800/hm2 was the best;(b) shrub diversity was significantly affected by tree density,the shrub diversity which in different tree density groups shows:low-density>mid-lower density>low-density>mid-higher density>high-density;(c) in different groups,the difference of tree spatial structure has different effects on shrub diversity,in the plots which showed a tree density of 2300 ~ 2800/hm2,a higher correlation relationship between tree spatial structure and shrub diversity could be observed.This indicates that shrub diversity could be changed via an adjustment tree spatial structure in that tree density.

Key words： Chinese pine plantation forest; spatial structure; shrub diversity; tree density; coupling relationship
