摘要
对福建茫荡山自然保护区小叶青冈林进行调查,根据各种群重要值,选取25个优势种,对其种间联结性进行计测和分析,并划分了生态种组。结果表明,优势种群间整体上呈正联结性;在300个种对中,具有明显正联结性的种对数占总种对数的11.67%,大多数种对表现为弱联结性或无联结性,各种群的分布相对独立。通过聚类分析,结合种间联结系数和各种群生态习性,将25个优势种群划分为3个生态种组。
The Cyclobalanopsis gracilis forest was investigated in Mangdangshan Nature Reserve in Fujian Province. Based on the population important values, 25 dominant populations were selected to analyze their interspecific association. Then the ecological species groups were plotted. The results showed that the dominant populations had general positive interspecific association, but the species pairs with significant positive associations were only 11.67 percent of the total 300 species pairs, and most of the species pairs showed weak interspecific association or without interspecific association. The investigated populations had characteristics of relatively independent distribution. According to the cluster analysis, the interspecific association coefficients and the species ecological habits,the 25 dominant populations were divided into three ecological species groups.
