摘　　要：叶片解剖性状是微观角度反映植物功能的重要特征。以西宁市4种小乔木叶片为材料,分析叶片表皮组织、海绵组织、栅栏组织及其衍生性状,评价4种植物对环境的适应程度。通过石蜡切片获得叶片内部微观形态特征,利用相关性分析、主成分分析和隶属函数分析对植物适应性进行评价。结果发现,4种植物均具有较厚的叶片和发达的栅栏组织,说明对环境的耐受性较强;模糊隶属函数分析显示4种植物适应性强弱排序为红宝石海棠>金叶榆>榆叶梅>紫丁香。结果表明对于叶片解剖性状的分析可以作为植物对环境适应性程度评价的有效手段,研究微观层面的适应特征有助于从机理层面解释植物的功能适应性。Leaf anatomical traits are important features that reflect plant function from a microscopic perspective.In this study,the leaves of 4 four plants in Xining City were used as materials to analyze the leaf epidermal tissue,sponge tissue,palisade tissue and its derivative trait parameters,and evaluated the adaptability of four plants to the environment.The microscopic morphological characteristics of the leaves were obtained by paraffin section,and the plant adaptability was evaluated by correlation analysis,principal component analysis and membership function analysis.The results showed that four plants had thicker leaves and developed palisade tissue,indicating that they had strong tolerance to the environment.Fuzzy membership function analysis showed that the order of adaptability of the four plants was ruby begonia>ulmus pumila>prunus triloba>syringa oblata.It shows that the analysis of leaf anatomical traits can be used as an effective means to evaluate the adaptability of plants to the environment and exploring the adaptation characteristics at the micro level helps to explain the functional adaptability of plants from the mechanism level.
