摘 要：Several plant micro-reserves were established to preserve the vegetation in local mountain areas during the construction of the Yanqing competition zone of the 2022 Beijing Winter *** spatial patterns of the main species in one of the micro-reserves and the factors affecting these patterns were characterized in this *** distribution of arbor species was found to be mostly aggregated,especially at fine scales(5 m).Minor species were found to be more aggregated than the major species in each forest *** spatial patterns were found to be affected by habitat heterogeneity,intraspecific relationships,interspecific competition,and seed dispersal *** heterogeneity was found to affect large-scale spatial patterns,and its effects were observed throughout population *** competition is another factor affecting the distribution of the species,and its effects were stronger during the later stages of population *** heterogeneity was found to affect competition among species and is key for species *** these processes are affected by the seed dispersal limitation,and intraspecific relationships are a legacy of seed *** point patterns can be used as a tool for the initial assessment of the status of communities within *** consideration of these relationships in the development,management,and formulation of policies for micro-reserves in mountainous areas will facilitate the achievement of conservation *** careful consideration of habitat conditions when selecting sites for micro-reserves establishment can promote species conservation.
