《说文解字》是东汉许慎所作纂集类字书，以540部首统摄9353正篆，并对每一正篆进行形义说解。《说文叙》称“理群类”为作书首要目的，反映了许慎自觉的形义类聚理念。从部首的确立，到辖字的归部与排列，再到训释的形成，《说文》的编写过程贯穿着形义的分类与聚合，体现出一定的类聚方法与文化理念。本文旨在通过逐层深入《说文》形义系统，研究其类聚思想的具体特点。 第一章论述《说文》类聚思想的历史渊源与理念自觉。《说文》类聚思想的历史来源有两方面，其一，先秦两汉时期的类聚思想经过萌芽发展为先秦诸子的哲学探讨，至秦汉时期形成系统的世界图式，为《说文》类聚提供了思想资源；其二，先秦两汉“小学”专书中的分类体例为《说文》类聚提供了方法启示。许慎自觉的字词类聚理念集中体现于《说文叙》，除此以外，一些具体的训释也反映着许慎的判分和聚合观念。 第二章论述《说文》部首结构中的类聚思想。就立部而言，部首的作用是作为辖字形义类聚的基本单位，在此基础上，基本部首通过形义分化生成衍生部首，完善了《说文》构意系统。基本部首的重要特点是以物象统摄形义，衍生部首亦携带相应的物象特点。《说文》部首的生成机制与《周易》思想密切关联。就部序而言，《说文》部首根据形义关联进行系联排列，进而形成表示相关构意的部首群。《说文》部序的总体结构体现了天地人的世界图式。 第三章论述《说文》部首辖字中的类聚思想。部首内部辖字的类聚与排列反映着许慎的重要分类思想：其一，共名与别名、整体与部分的排序体现出判分思想；其二，自然属性事物与社会属性事物的排序体现出天人之分；其三，对于人类与动物的严格秩序和对于美恶之分辖字的排序体现出价值判断；其四，字序中的专科知识体现出具体物类规律的阐释。 第四章论述《说文》训释中的类聚思想。义界体现着词义之间的共性和差别，义界类聚是意义系统形成的重要基础，《说文》义界的多重来源反映了许慎自觉的类聚意识。《说文》训释系统中存在多种意义关系，体现出许慎的类属思想、时间观念和对立思维。 结语部分总结了《说文》类聚思想的特点与意义。在思想史和“小学”专书的双重维度中，《说文》类聚思想在方法体例和文化观念两方面都具有鲜明的民族特点和深刻的历史价值。

Shuowen Jiezi is a compilation book written by Xu Shen of the Eastern Han Dynasty. 9353 characters are organized into 540 radicals, and each character is following with an integrated explanation of the forms and meaning. Shuowenxu said "organizing the groups" as the primary purpose of the book, reflecting Xu Shen's conscious concept of conception and aggregation. From the establishment of radicals, to the organization of the jurisdiction, and the formation of interpretation, the writing process of the Shuowen runs through the categorization and aggregation of the forms and meanings, which reflects certain methods of aggregation and cultural concepts. The purpose of this paper is to study the specific characteristics of the idea of clustering by going deep into the Shuowen form system. The first chapter discusses the historical origin and concept consciousness of the ideology of Shuowen. There are two historical sources of the thoughts of Shuowen. Firstly, the thoughts of gathering in the Pre-Qin and Han Dynasties sprouted into the philosophical explorations of the pre-Qin philosophers, and form a systematic world schema in the Qin and Han dynasties. The clustering provides ideological resources. Secondly, the categorization style in the pre-Qin and Han dynasty language and writing books provides a methodological inspiration for the clustering of Shuowen. Xu Shen's self-conscious concept of word clustering is mainly embodied in " Shuowenxu." In addition to this, some specific exegetical interpretations also reflect Xu Shen's judgment and aggregation concept. The second chapter discusses the idea of clustering in the radical structure of Shuowen. As far as the establishment is concerned, the function of the radicals is to serve as the basic unit for the formation of the form of the word. On this basis, the basic radicals form derivative radicals through form differentiation and improve the construction system of the Shuowen. The important feature of the basic radicals is the concept of imagery, and the derived radicals also carry the corresponding characteristics of objects. The generative mechanism of the Shuowen radical is closely related to the idea of Zhouyi. As far as the order is concerned, the Shuowen radicals are arranged in a tie according to the form and meaning relation, and form a group of radicals that represent the relevant structure. The overall structure of the preface to the Shuowen reflects the world map of heaven and earth. The third chapter discusses the idea of clustering in the words of the head of the Shuowen .The clustering and arrangement of the internal governing words of radicals reflect Xu Shen's important classification thoughts: firstly, the common name and alias, the ordering of the whole and part reflects the idea of judging.Secondly, the sorting of things with natural attributes and social attributes. Thirdly, the human-oriented thinking is reflected in the orderly arrangement of human-related ministries and the strict order of humans and animals. Fourthly, the ordering characteristics of opposing characters, especially good and bad, are reflected in the The difference between the nice and evil. The fourth chapter discusses the idea of clustering in the exegetical interpretation of Shuowen. The meaning circle reflects the commonality and difference between words and meanings. The polymorphism of righteousness is the important basis of the formation of the meaning system. The multiple sources of the meaning circle of the "word of writing" reflect the forming mechanism of the commentary. There are many kinds of meaning relations in the exegetical interpretation system of Shuowen, reflecting Xu Shen's genre thought, time concept and opposition thinking. The conclusion part summarizes the characteristics and significance of the ideology of Shuowen.In the dual dimension of the history of thought and the book of linguistics, the idea of gathering in the Shuowen has distinctive national characteristics and profound historical values in both method style and cultural concept.
