摘要: 为揭示中亚热带典型河岸带阔叶林群落的结构特征、数量特征和干扰强度的耦合关系,根据干扰强度的不同,在江西武夷山保护区内选取3条主要水系进行阔叶林群落调查,共统计到河岸带维管束植物93科174属304种,分别占保护区维管束植物总数的41.5%、18.0%、11.9%。物种组成以壳斗科(6属22种)、山茶科(7属22种)、樟科(6属16种)、蔷薇科(8属16种)为主。不同干扰强度下的河岸带植被群落相似性Jaccard系数均在0.2～0.3之间,各群落优势种完全不同,且存在特有分布的物种,但群落乔木层优势种优势度(重要值)差异不显著(P > 0.05)。不同干扰强度下,物种数量、群落Jaccard系数、丰富度指数、多样性指数、均匀度指数总体上为:轻微干扰 > 中等干扰 > 无干扰;而乔木的平均高度和平均胸径却为:无干扰 > 中等干扰 > 轻微干扰。研究结果表明,江西武夷山河岸带阔叶林以常绿阔叶树种为主,但不同干扰梯度下群落的结构和数量特征差异性较大。Abstract: We investigated the coupling relationship between structural and quantity characteristics of typical riparian zone broad-leaved forest communities under different disturbance intensities. Three river systems were selected in the Jiangxi Wuyi Mountain Nature Reserve in mid-subtropical areas to survey riparian zone broad-leaved forest communities under different disturbance intensities. Results showed there were 93 families, 174 genera, and 304 species of vascular plants, accounting for 41.5%, 18.0%, and 11.9%, respectively, of the reserve's total vascular plants. The species mainly consisted of Fagaceae (6 genera, 22 species), Theaceae (7 genera, 22 species), Lauraceae (6 genera, 16 species), and Rosaceae (8 genera, 16 species). Dominant species of the riparian vegetation communities differed significantly, and endemic species existed in all disturbance intensity sample plots. However, there were no significant differences in the importance values of the dominant species in the tree layer (P> 0.05). The community Jaccard similarity coefficients were between 0.2 and 0.3 under different disturbance intensity sample plots. According to the ANOVA test, the number of species, community Jaccard similarity coefficients, richness index, diversity index, and evenness index were:Minor disturbance > Medium disturbance > No disturbance. However, average height and average DBH of the trees were:No disturbance > Medium disturbance > Minor disturbance. The results suggested that evergreen broad-leaved trees were common in the Jiangxi Wuyi Mountain riparian zone broad-leaved forest. Additionally, there were significant differences in the structural and quantity characteristics of the different disturbance intensity forest communities.
