摘要

为探究森林群落种间关联格局与物种生境偏好的关系, 采用空间点格局分析方法和点过程模型, 分析了浙江天童国家森林公园20 hm2常绿阔叶林样地109个木本植物的种间关联格局及种-生境关联, 结果表明: ①天童样地中, 种间负关联比例高于种间正关联, 具有显著关联的种对比例随尺度增加而增加; ②89.9%的物种至少与一类生境显著关联, 73.4%的物种与生境显著正关联, 65.1%的物种与生境显著负关联; ③在较大尺度上(> 20 m), 种间空间关联结果与种对的生境偏好类型表现出很好的一致性, 说明生境的异质性是形成较大尺度种间关联格局的重要原因; 而在较小尺度上(< 5 m), 种间关联格局与种对的生境偏好没有明显关系, 可能受到其他生态学过程的影响. 研究结果为进一步探究常绿阔叶林物种的共存机制提供了理论依据.

Abstract

The objective of this study was to clarify the relationship between interspecies associations and species habitat preferences in Tiantong National Forest Park. A total of 109 species of 20 hm2 evergreen broad-leaved forest plots were selected and tested for interspecies associations and species-habitat associations. The results indicated that: ① the ratio of species pairs with significant associations increased with spatial scale and the ratio of negative associations was higher than positive; ② 89.9% of species were significantly correlated with at least one habitat variable, including 73.4% of species positively and 65.1% of species negatively correlated with habitats; ③ at scales larger than 20 m, the results of interspecies associations were consistent with those of species pair habitat preferences; but at smaller scales (i.e., < 5 m), most species pairs did not show significant interspecies associations, indicating there are not habitat preferences but rather other ecological processes influencing interspecies association patterns. The results provide a theoretical basis for further understanding the mechanism of species coexistence in evergreen broad-leaved forests.

Key words： interspecies association; habitat preference; point pattern; scale; wood plants; Tiantong National Forest Park
