摘要:
基于对凤阳山自然保护区常绿阔叶林的样地调查,采用定量分析的方法,测算了10种乔木层优势种群的生态位宽度、生态位相似性和生态位重叠。结果表明:(1)分别用Levins和ShannonWiener两指数测得的生态位宽度结果存在较大的差异性,但两种结果均表明木荷的生态位宽度值最大,其生态位宽度值B(L)i和B(sw)i分别为0.771、1.325。(2)该群落优势种群间的生态位相似性比例较大,表明优势种群之间对资源的利用有较高的相似程度。生态位相似性比例与生态位宽度之间无明显的相关关系。(3)该群落优势种群间的生态位重叠值较大,且Lih值与Lhi值基本一致,说明优势种群间有相似的生态学特性。另外,生态位相似比例大的生态位重叠值也较大,反之亦然。
Abstract:
Plots investigation based on evergreen broadleave forest in Fengyangshan Nature Reserve, we used the method of quantitative analysis to measure the niche breadths, niche similarity and niche overlap of ten dominant tree species. The results showed that: (1)The niche breadths were measured by Levins and ShannonWiener index respectively, there were many differences between the results, but the largest niche breadth of them was Schima superba, the value of B(L)i and B(sw)i were 0.771 and 1.325 respectively. (2)The niche similarities among the dominant species were very big, this showed that they had high similarity in using the resources. There was no obvious correlation between niche similarity and niche breadths. (3)The niche overlap among the dominant species were very big, and the values of Lih and Lhi were almost the same, this fully showed that dominant species had similar ecological characteristics. If the niche similarity was big the niche overlap was big, so did the opposite.
