摘    要:以乔木层树种重要值为指标,Pearson相关系数为测度距离,运用SPSS软件对双峰山国家森林公园人工林类型进行聚类划分,并分析了各群落物种多样性特征.根据聚类结果,按优势种命名原则,将双峰山森林群落划分为马尾松群落、杉木群落和柳杉 杉木群落,其中杉木群落物种多样性水平相对较高;乔木层、灌木层和草本层3个层次的物种多样性水平呈现出灌木层较高,草本层次之,乔木层较低的变化规律.但总体上,这些群落植物种类较少,物种多样性水平尤其是乔木层物种多样性水平低,应采用人工间伐、引入观赏价值高的乡土花卉及树种等方式促进群落物种多样性水平的提高,同时丰富森林景观.

关 键 词:人工林  生物多样性  双峰山国家森林公园

Abstract:The plantations of Shuangfeng Mountain national forest park were classified with SPSS software by tree IV value and Pearson correlation coefficient and further the species diversity of community was measured for ecological construction of national forest park.The plantations were classified into three communities which were Cunninghamia lanceolata community,Pinus massoniana community and Cryptomeria fortunei+C.lanceolata community according to dominant species principle.Among three communities,C.lanceolata community had more high species diversity.There was the highest species diversity in the shrub layer and the lowest one in the tree layer among three layers(tree,shrub and herb layer).However compared with zonal climax,these communities had few species and low species diversity,especially in tree layer.Methods,such as the interval cutting and introducing ornamental flower and tree,should be used to increase the species diversity of community and improve forest landscape.
Keywords:Plantation   Diversity   Shuangfeng Mountain national forest park
