滇中次生常绿阔叶林优势树种的空间格局
Spatial patterns of dominant species in secondary evergreen broad-leaved forest in central Yunnan, Southwest China.
摘要
Abstract
By using Ripley' s point pattern analysis, the spatial patterns of the dominant species Cyclobalanopsis glaucoides and Keteleeria evelyniana in the secondary evergreen broad-leaved forest in central Yunnan of Southwest China as well as the spatial associations among the individuals of the two species with different DBH classes were analyzed. Overall, the individuals of the two species with different DBH classes were in uniform distribution, indicating that the growth of the two populations was in stable period. The two species and their individuals with different DBH classes had a clumped distribution. With the increase of DBH class, the aggregation degree of C. glaucoides had a decreasing trend, while that of K. evelyniana decreased first, increased then, and decreased at last. A positive or no significant spatial association was observed among the saplings, juvenile trees, and adult trees of the two species. At different spatial scales, the two species of different DBH classes had less association, possibly because of the greater differences in the survival strategies of the two species. It was suggested that in the restoration of the forests in central Yunnan, it would be essential to control the plant population density and attend to the interspecific interaction to build an appropriate structure of the community.关键词
