Mixed Afforestation Effects Analysis of Liquidambar formosana Hance and Altingia chinensis in Different Aspects and Slope Positions
摘要
Abstract
[Objective]To study the growth and interspecific competition of the artificial mixed forest of Liquidambar formosana Hance and Altingia chinensis.[Method]Based on the survey data of 16 a L. formosana Hance and A. chinensis from a mixed forests, to analyze the tree height, DBH, average maximum crown, the individual tree volume and the stand volume of the two species.[Result]The difference in aspects and slope position had no significant effect on the preservation rate of L. formosana Hance. The preservation rate of A. chinensis on the semi-sun slope was larger than that of the sunny slopes, and gradually increased with the increase of the slope position. At the same time, the average tree height, DBH and average single-tree volume of L. formosana Hance and Altingia chinensis on the sunny slopes were larger than the semi-sunny slopes, and both gradually decreased with the increase of the slope position. The stand volume of L. formosana Hance on the sunny slope was higher than that of semi-sunny slope, and it gradually decreased with the increase of slope position, but A. chinensis showed a completely opposite trend. At the same time, the tree preservation rate, average DBH, average tree height, average tree volume and stand volume of L. formosana Hance under the sunny slope were significantly higher than those of the A. chinensis under the same slope. However, under the semi-sunny slope, there was no significant difference between L. formosana Hance and A. chinensis in average tree height, average DBH, stand volume and unit stand volume, but the preservation rate of L. formosana Hance on the lower slope was significantly higher than that of A. chinensis, there was no significant difference on the mid-slope and upper slope. [Conclusion]Under the conditions of sunny slopes, especially in the middle and lower slopes, the growth of L. formosana occupies an absolute advantage, which leads to the inhibition of the growth of A.chinensis.In the semi-sunny slope area, limited resources and resources have intensified competition between the two species.关键词
