河南白云山落叶阔叶林群落性系统的数量特征及生态关联性

Quantitative characteristics and ecological correlations of sexual system in a deciduous broadleaf forest of the Baiyun Mountains of Henan Province, China

  • 摘要: 基于河南白云山5 hm2落叶阔叶林统计该地区气候过渡带森林群落植物性系统的数量特征,使用重要值、相对多度、群落多样性指数分析性系统的分布状况,并采用方差分解分析环境对植物性系统的解释率。结果显示:白云山5 hm2样地中两性花有54种(58.06%),其中20种为雌雄同株(21.51%),19种为雌雄异株(20.43%);地形和空间因子对性系统的解释率最高;空间过程对植物群落性系统的解释比例较大。暖温带-亚热带生态过渡区雌雄同株植物占比例较大,结果更符合温带森林的繁殖特征;地形对白云山样地性系统的组成有一定影响;扩散限制是影响木本植物群落性系统的重要生态过程。

     

    Abstract: Exploring the quantitative characteristics of forest communities in a subtropical-to-temperate transition zone from the perspective of plant sexual systems can provide valuable information for biodiversity conservation and species coexistence. In this study, woody plants in the subtropical-to-temperate transition zone of the Baiyun Mountains were investigated and the quantitative characteristics of their sexual systems were analyzed. Variance of variance partition analysis environment for sexual system. Results showed that of the 93 woody seed plants recorded in the 5 hm2 plots, 56 species were hermaphroditic (58.06%), 20 species were monoecious (21.51%), and 19 species were dioecious (20.43%). The proportion of monoecious plants was larger in the warm temperate-subtropical transition zone, consistent with the reproductive characteristics of temperate forests. Topographic factors have influenced the composition of the sexual systems of woody plants in the Baiyun Mountains. Furthermore, diffusion restriction is an important ecological process affecting the woody plant community.
