Abstract

[Objective]By investigating the intraspecific and interspecific competition of Pinus yunnanensis natural forest in Tianchi Natural Reserve of Yunlong County, Yunnan Province to reveal the rule of dynamic changes of intensity of competition within the community and the ecological adaptation mechanism of P. yunnanensis.[Method]Based on survey of substantial community plots, the competition intensity of forest stand, objective trees, competitive trees were analyzed by using Hegyi individual competitive indices (CI) model. The function model between DBH and the whole competition, intraspecific competition, interspecific competition were established by regression analysis method. [Result]The intraspecific and interspecific competition intensity of P. yunnanensis accounted for 80.16% and 19.84% in the total competition intensity, respectively, indicating that the competitive trees of P. yunnanensis natural forest were mainly come from intraspecific competition. The order of the intraspecific and interspecific competition intensity of the main accompanying species at the community level was: intraspecific > Viburnum cylindricum > P. armandii > Lyonia ovalifolia > Rhododendron decorum > Quercus aliena > Rhododendron delavayi > Alnus nepalensis. [Conclusion]There was a significantly negative correlation between the competition index of P. yunnanensis with the whole forest, accompanying species, intraspecific and the DBH of the objective trees, and nearly conformed to power function (CI=AD-B). The larger the DBH of the objective trees, the smaller the competitive trees in P. yunnanensis natural forest. The results predicted by the model is that when the DBH of P. yunnanensis is larger than 20 cm, the competitions will be less in intensity. The medium and young forests of P. yunnanensis with DBH below 20 cm should be the focus of tending and management.
