摘要:
采用Levins、Hurlbert、Pianka公式,对安徽黄山、浙江天目山、浙江白云山、江西庐山4个地区的迎春樱群落进行了生态位分析,结果表明:不同地区群落中迎春樱具较高的生态位宽度,其Levins和Hurlbert生态位宽度的测度结果均列各群落第一,4个地区种群两种生态位宽度值分别为 0.632、0.654,0.721、0.748和0.664、0.833,0.734、0.849,迎春樱在群落中具有一定的优势,对资源利用充分,具有较强的环境适应性; 从Pianka生态位重叠值来看,生态位重叠值≥0.6的种,在安徽黄山、浙江天目山、江西庐山、浙江白云山迎春樱群落所占比例分别为52.78%、42.86%、36.11%、60.00%,不同地区迎春樱群落生态位重叠值较高,种间竞争激烈,迎春樱多被排挤于林缘或疏林下,在人为干扰破坏剧烈的地段,种群有衰退的趋势。
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; ② From 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. discoidea much margin of excluded the woods or in thin forests, severe section of the human disturbance, the population has a tendency to decline.
