摘　　要：基于武夷山风景区天然林的调查数据,以不同高度作为一维资源位状态,以个体多度为生态位计测的资源状态指标,对群落中的15个优势树种进行生态位计算和分析.结果表明,杉木、米槠、马尾松的生态位宽度BSW,i与BL值均排在前3位.说明这3种天然林在各个高度资源级中分布较为均匀,具有较宽的资源利用谱,能够充分地利用资源.此外,高度生态位重叠值有58对大于等于0.5,其中黄瑞木和黄毛润楠的生态位重叠值最大,其值为0.935 9,说明两个窄生态位的种对之间可以有较大的生态位重叠.Based on the investigation of the natural forests in Wuyishan Scenery District, the niche characteristics of 15 dominant populations were described and analyzed, with height class as the resource state and tree abundance as the index. The results indicated that the value of Bsw.i and BE of Cunninghmia lanceolata, Castanopsis Ca rlesii and Pinus massoniana took up the first three place,which showed that their distribution were relatively even in each height class. Meanwhile it also showed that they had a relatively wide resource utilization spectrum and the resources could be adequately used. In addition,there were 58 pairs whose niche overlap 〉0. 5（including 0. 5） ,the pair -Adinandra mellettii and Machilus chrysotricha of which has the largest niche overlap value -0. 935 9 , indicating a high niche overlap could occur between two species with narrow niche breadth.
