摘要: 基于2×2联列表,应用种间共同出现百分率(C)和联结系数(D)等公式测定了浙江省石垟森林公园常绿阔叶林16种主要乔木和23种主要灌木种群的种间联结性。结合已有的生态位研究结果,共同探讨植物种群之间的联结状况。结果表明:乔木层中木荷Schima superba,青冈栎Cyclobalanopsis glauca,马银花Rhododendron ovatum和麂角杜鹃Rhododendron latoucheae与其他多数种群间的联结性较高,而雷公鹅耳枥Carpinus viminea,老鼠矢Symplocos stellaris,南酸枣Choerospondias axillaris,浙江新木姜子Neolitsea aurata和构栲Castanopsis tibetana等与其他种群间的联结性相对较弱,整个群落呈现出相对稳定的态势;灌木层253个种对中,CD<-30%的种对数占59.3%,绝大多数种对表现为弱联结性或无联结性。种间联结性越强,其生态位重叠值越大,种间联结性越弱,其生态位重叠值越小。

Abstract: To explore the association between dominant plant populations, the interspecific associations of dominant tree and shrub populations together with niche plants in an evergreen broadleaf forest of Shiyang Forestry Center, Zhejiang Province were studied based on a 2×2 contingency table using percentage of co-occurrence(C) and association coefficient(D). Results showed that in the tree layer Schima superba, Cyclobalanopsis glauca, Rhododendron ovatum, and Rhododendron latoucheae had higher associations with a majority of the other populations, whereas as Carpinus viminea, Symplocos stellaris, Choerospondias axillaris, Neolitsea aurata, Castanopsis tibetana, and other species had relatively weak associations. Nevertheless, the entire community was relatively stable. In the shrub layer 83.4% of the total 253 species pairs, had a co-occurrence of less than 10%, while 59.3% had association coefficients(D) less than -30%. Most of the shrub species pairs showed weak or no interspecific association. Also, greater intensities of association had larger niche overlap values, whereas weaker associations had smaller niche overlaps.
