摘要
对福建武夷山野生早樱群落灌木层12个种群进行生态位宽度、生态位重叠和生态位相似性比例的计算与分析的研究结果表明,该群落灌木优势树种中,鹿角杜鹃、柃木、木荷、山矾和交让木具有较大的生态位宽度,分别为0.8425、0.8404、0.7664、0.6969、0.6962和0.9864、0.9759、0.7856、0.6587、0.6565;而青榨槭和野生早樱的生态位宽度值最小,其B i值和Ba值分别为0.5790、0.4611和0.4395、0.3087。
Based on one resource dimension of communities quadrats and importance value, the niche characteristics of twelve dominant shrub populations in Cerasus subhirtella vat. ascendens community on Wuyi Monntain of Fujian Province were calculated and analyzed by using Levins, Hurtlbert, Pianka and Schoener formulas. The result showed that among the shrub populations, the Levins and Hurlbert＇s niche breadths of Rhododendron latoucheae, Eurya japonica, Schima superba, Symplocos sumuntia and Daphniphyllum macropodum were 0. 8425, 0. 8404, 0. 7664, 0. 6969, 0. 6962 and 0. 9864, 0. 9759, 0. 7856,0. 6587, 0. 6565. While Acer davidii and C. subhirtella var. ascendens were smaller, with the Levins and Hurlbert＇s niche breadths 0. 5790, 0. 4611 and 0. 4395, 0. 3087 respectively.
