摘　　要：以镜泊湖熔岩台地17种草本植物为研究对象,对其叶厚度、比叶面积、气孔密度、叶组织密度等叶片性状进行分析,探究这17种草本植物叶片形态性状的差异。结果表明:镜泊湖熔岩台地17种草本植物中的叶厚度、气孔密度、叶脉密度、叶组织密度最大的植物种均为斑叶堇菜,比叶面积最大的植物种为野大豆;与多年生植物相比,1年生植物的叶片比叶面积和气孔密度普遍比多年生植物的要高,而叶厚度、叶脉密度和叶组织密度则低于多年生草本植物;17个物种间叶片的各个性状都存在明显差异,体现了植物以不同的功能性状适应环境。In this study,17 herbaceous plant species in the lava platform of Jingpo Lake were used as the research objects,and the leaf traits of herbaceous plants,such as leaf thickness,specific leaf area,stomatal density,leaf tissue density,etc.,were analyzed,and the differences in leaf morphological traits of 17 herbaceous plant species were explored.The results showed as follows:among the 17 herbaceous plant species in the lava platform of Jingpo Lake,the species with the highest leaf thickness,stomatal density,leaf vein density and leaf tissue density were all Viola variegata,and the species with the largest specific leaf area were Glycine soja;compared with perennial plants,the leaf specific leaf area and stomatal density of annual plants were generally higher than those of perennial plants,while the leaf thickness,leaf vein density and leaf tissue density were lower than those of perennial herbs;there were obvious differences in leaf traits among the 17 species,indicating that plants adapted to the environment with different functional traits.
