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 interspecies 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 forest, 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 besides B. platyphylla + P. tabulaeformis mixed forest, which maybe convert to be a consocies.
