%X 叶片解剖特征是指示植物对特定环境适应性的主要指标，也是展现叶片功能及其重要程度的凭据。为研究我国东部典型亚热带常绿阔叶林优势木本植物的生态适应策略，以金华北山为采样地，采用叶面仪、徒手切片法和显微观察技术，对叶片解剖结构进行测量，分析解剖性状在种间及种内的差异，阐释其与环境的相互关系。结果表明：栅栏组织的厚度变异最大，海绵组织厚度的变异最小，且不同植物间的同一性状值大小差别较大。植物功能性状的种内、种间变化较大，且不同性状间存在差异，TS的种内变异最高，TP及TP/TS的种内变异均较小。物种差异对TP/TS性状变异的解释度均最高，生活型和生长型的交互作用对植物叶片性状变异的影响大于生活型和生长型的单独影响。<br />
Leaf anatomical characteristics are the main indicators of plant adaptability to a specific environment, and also the evidence of leaf function and its importance. In order to study the ecological adaptation strategies of the dominant woody plants in the typical subtropical evergreen broad-leaved forest in eastern China, the leaf anatomical structure of the leaves was measured with foliar surface analyzer, freehand slice method and microscopic observation techniques, and the differences between the anatomical traits and the environment were analyzed. The results showed that the thickness variation of palisade tissue was the largest, the thickness variation of sponge tissue was the smallest, and the value of the same trait was different among different plants. The intraspecific and interspecific variation of plant functional traits was large, and there were differences among different traits. The intraspecific variation of TS was the highest, and the intraspecific variation of TP and TP/TS was small. The interaction of life type and growth type had a greater effect on the variation of leaf traits than that of life type and growth type alone.
