物种共存机制和生物多样性的维持一直被认为是群落生态学研究的重要组成部分。作为生态位分化的重要机制之一，基于生态位分化的物种共存理论近年来受到人们的关注。因此，地形通过生境异质性的形成影响物种的分布和共存。黑龙江枫林国家级自然保护区30公顷的红松阔叶混交林动态样地。我们使用环面平移法研究了物种-栖息地的关联性。我们的目标是了解不同物种、生命形式(灌木、乔木)和耐荫(耐光、耐中、耐荫)在不同生命阶段(幼树、幼林和成熟期)之间的栖息地相关性，为生态位理论在温带森林中的作用提供进一步的证据。在我们测试的33种物种中，28种(84.8%)至少与一种生境类型显著相关。正向联想在山谷和坡地(阴天和晴朗)较频繁，而在山脊较少。在3个生活期(幼苗期11个，幼龄期11个，成熟期12个)，与5种生境有34个显著正相关。乔木与谷地呈正相关，灌木与晴朗、山脊呈正相关。大多数物种的栖息地偏好在不同的生活阶段发生了变化，但只有栎属、山毛榉、蒙古栎属、云杉属和乌龙头枫属例外，它们在各个阶段都与相同的生境有一致的关联性。中耐性乔木和中耐性灌木在三个生命阶段均与晴天呈正相关。大多数物种在样地中表现出栖息地偏好。这些结果表明，生态位理论在物种共存中发挥着重要作用。大多数物种在不同的生活阶段与栖息地没有一致的关联性。
Species coexistence mechanisms and maintenance of biodiversity have long been considered important components of community ecology research. As one of the important mechanisms, species coexistence theory based on niche differentiation has received attention in past years. Thus, topography, through the formation of habitat heterogeneity, affects species distributions and coexistence. A 30-ha dynamic plot of mixed broadleaved-Korean pine (Pinus koraiensis) forest is located in the Heilongjiang Fenglin National Nature Reserve. We examined species–habitat associations using the torus-translation method. We aim to understand the habitat associations of different species, life forms (shrubs, trees), and shade tolerance (light-demanding, midtolerant, shade-tolerant) across life stages (sapling, juvenile and mature), providing further evidence for the role of niche theory in temperate forests. Of the 33 species we tested, 28 species (84.8%) were at least significantly associated with one habitat type. Positive associations were more frequent in the valley and slope (shady and sunny) and less frequent on the ridge. Thirty-four significant positive associations with the five habitats were detected at three life stages (11, 11 and 12 at the sapling stage, juvenile stage, and mature stage, respectively). The trees were positively associated with the valley, and the shrubs were positively associated with sunny and ridge. The majority of species’ habitat preferences shifted among different life stages; the exceptions were Corylus mandshurica, Maackia amurensis, Quercus mongolica, Picea jezoensis and Acer ukurunduense, which had consistent associations with the same habitat at all stages. The midtolerant trees and midtolerant shrubs were positively correlated with sunny across the three life stages. Most species show habitat preferences in the plot. These results indicate that niche theory plays an important role in species coexistence. Most species have no consistent association with habitat at different life stages.
