迎春樱群落主要种群生态位研究
Study on the niche of the main populaition in Cerasus discoidea community
摘要
Abstract
Using Levins, Hurlbert, Pianka formula, the four areas of communities niche were analyzed, the results showed that:① From the Levins, Hurlbert niche breadth of view, different regions of communities, Cerasus discoidea niche with higher width, the Levins and results Hurlbert niche breadth measure each community are listed first, niche breadth were 0�632,0.654,0�721,0�748 and 0�664,0�833,0.734,0�849, C. discoidea has certain advantages in the community, for the full utilization of resources, with a strong environmental adaptability;②From Pianka niche overlap, the species of niche overlap value 0.6 or more, Huangshan in Anhui, Tianmu Mountain in Zhejiang, Lushan Mountain in Jiangxi, Baiyun Mountain in Zhejiang community proportion of C. discoidea was 52�78%, 42.86%, 36.11%, 60.00%, different areas of C. discoidea community niche overlap value is higher, the interspecific competition is intense, C. dis-coidea much margin of excluded the woods or in thin forests, severe section of the human disturbance, the population has a tendency to decline.关键词
