摘　　要：运用生态位宽度、生态位重叠值以及生态位相似比例等指标对武夷山风景名胜区天然林中15个主要种群的生态位特征进行测定与分析。研究结果表明:武夷山风景名胜区天然林主要种群绝大多数为狭生态位,除个别种群的生态位宽度(BL)大于0.54外(如马尾松、黄毛润楠),大多数种群的生态位宽度(BL)小于0.4。种群之间的生态位相似性比例和生态位重叠指标均较高。Niche characteristics of 15 major populations of natural forest in Wuyishan Scenery District were analyzed by quantita- tive method. The niche characteristics include niche breadth, niche proportional similarity and niche overlap. The results indicate that almost all the species investigated have narrow niche, with niche breadth （BL ） of a few populations such as Pinus masoniana and Machilus chrysotricha 〉 0.54, and others BL 〈 0.4. In addition, niche proportional similarity index and Levin overlap index of all species pairs are high in sub-tropical forests.
