中文摘要 园林树木是城市绿地发挥综合效益的主体，其根系形态是影响植物抗性的关键生物学特性。文章首先采用文献综述法归纳出一套综合的根系形态指标体系，包括根系总生物量、根系直径、根系结构分布、根系密度4类共16项；进而基于该指标体系对所研究树种的根系形态结构进行聚类分析，并通过图示语言描述根系形态，采用象形的方法概括根系类型，共得到M型、W型、A型和T型4种根系类型；最后根据树种个体生长情况、遗传特性的影响情况，建议未来根系形态结构聚类分析应当进一步结合树种科属关系辅助判断根系类型或扩大数据样本研究，以期为提升园林树木适应和缓解气候变化的服务功能研究提供基础资料。

英文摘要 Landscape trees are the important component of urban green space to give play to comprehensive benefits, and their root morphology is the key biological characteristics affecting plant resistance. The paper concludes a comprehensive indicator system of root system morphology after the literature review, which includes 16 indicators under 4 principles of total root biomass, root diameter, root structural distribution and root density. With the indicator system, a cluster study is carried out for root system morphology and structure of the 14 popular landscape tree species in study. The graphic language is used to describe root system morphology, and the pictographic method is used to summarize the types of root system, including M type, W type, A type and T type. In view of the individual growth of tree species and impact of genetic features, it is suggested that in the cluster study of root system morphology and structure, more effort should be made to further identify the types of root system or expand the data and samples. The results would help further study root system and provide the data and information for improving the functions of landscape trees in climate change adaptation and mitigation.
