子午岭典型森林群落建群种空间格局特征
Spatial pattern of dominant species in typical forests on Mt.Ziwuling
摘要
Abstract
Based on the spatial data of dominant woody species about nine typical forests in Mt. Ziwuling and the point pattern analysis theory (O-ring function),the spatial pattern and interspe-cies relationships of these species were analyzed.The results showed that the dominant species in Quercus wutaishanica forest and Pinus tabulaeformis plantation present clumpy distribution for small,even for medium and random for large scale.In other four forests,P .tabulaeformis for-est,Robinia pseucdoacacia plantation,Populus davidiana forest and Betula platyphylla forest, the main dominant species distribute clumpy for small scale,then tende to random distribution with spatial scale increasing.In three mixed forests,there was no correlation between dominant species expect B.platyphylla + P .tabulaeformis mixed forest,in which positive relationship presented periodically every 20 m.It is concluded that the typical forests in this area are stable be-sides B.platyphylla + P .tabulaeformis mixed forest,which maybe convert to be a consocies.关键词
