摘    要: 对分布在不同生态环境条件下的硬叶常绿阔叶林建群种高山栎组植物叶的形态解剖特征进行了比较研究。结果表明,高山栎组植物叶的形态结构兼有非肉质旱生植物和高山植物的性状,这是它们对生态环境广泛适应的基础。每一个种除气孔器类型及腹面二层表皮细胞性状比较稳定外,其他性状,如气孔的大小和密度、表皮细胞的形状、垂周壁的类型、叶片的厚度、角质膜的厚度均受环境条件修饰,不是稳定性状,不具分类学意义。对同一个种的不同生活型,如乔木、小乔木和灌木,在解剖结构土没有明显的区别特征。地中海的冬青栎(Quercusilex)的表皮特征和高山栎组植物有很大的相似性。

关 键 词:硬叶常绿阔叶林  高山栎组  形态解剖特征

Abstract:The morphological and anatomical features of Quercus Section Suber,the dominant species of the sclerophyllous evergreen broad leaved-forest,from different habitats were compared The results show that Quercus Section Suber possesses dual morphological characteristics of non-succulent xerophyte and al-pine plants.This is believed to be the basis for them to be adapted to a wide range of environmental conditions. The size and density of the stomata,the shape and pattern of the anticlinal walls of the epidermal cell5,and the thickness of leaves and cuticles were modified to a large extent by the ecolo,gical environment. On the contrary,the types of stomatal apparatus and the two layers of the adaxial epidermal cells are stable characteristics with im-portant value for classification.Quercus ilex,which is mainly distributed in the Mediterranean basin has similar epidermal features to Quercus Sect.Suber.
Keywords:Sclerophyllous evergreen broad-leaved forest  Quercus Sec-tion Suber  MorpholoRical and anatomical features  Ecoiogical adaptation
