| 摘 要： | 应用生态位空间分割法，分别考虑资源利用率与否测定毛竹混交林多维资源空间中主要种群多维生态位宽度及多维生态位重叠，结果表明：考虑资源利用率与否对多维生态位宽度的测定有较大的影响，毛竹混交林中主要种群的多维生态位宽度与物种的生物学特性及竞争力密切相关，同一生境中物种的多维生态位重叠可通过生态位分化而减少竞争，研究毛竹混交林主要种群多维生态位特征对毛竹混交林营造具有指导作用．表8参24． |

CHARACTERISTICS OF MULTI-DIMENSION NICHE OF DOMINANT POPULATION IN THE MIXED PHYLLOSTACHYS HETEROCYCLA COMMUNITY |
|
| Abstract: | Based on the principle of niche space compartmentalization, the characteristics of multi-niche breadth and multi-dimension overlap of dominant populations in the mixed Phyllostachys heterocycla communities were studied. The results showed that resources availability affected niche breadth greatly. Multi-dimension niches of dominant populations in the mixed P. heterocycla communities were nearly correlated with biologic characters and competition of species. Multi-niche overlap in the same habitat decreased competition by differentiating niche. The results of this study can be applied for the plantation of mixed P. heterocycla forests. Tab 8, Ref 24 |
