本文主要对战国官玺的章法进行了研究，发现战国官玺的章法具有地域性和共通性，提出章法可以作为古玺分域的标准之一。近年来随着大量古玺资料的出土，古玺分域研究成为了当下学术界热潮，古文字学界一般以官职、姓氏、文字风格、钮制和吉语内容作为主要的分域标准。本文提出了新的分域方法，即通过章法来探讨其地域性与共 通性。通过研究发现，战国地域官玺在特定章法中具有独一性，如独有面形样式，独有文字顺序排布等，有较大的探讨空间。 本文主要探讨范围为战国齐、楚、燕、三晋等四个地域的官玺，分为三个章节来进行概述。一、概述古玺分域情况，例举已有分域方法。二、官玺章法具有地域性，可以 通过“U”形排布、留白位置、聚散形态、面形样式、字数排布和合文符号使用位置等 六个不同的视角进行论证分析。三、官玺章法具有共通性，部分地域官玺在合文处理相 同自名时也呈现出这一特点，具有一定的研究空间。目前古玺分域的样式还不够完善， 还存在大量分域困难的古玺，新的分域方法有助于解决这一问题。另外，本文通过《古玺印图典》《盛世玺印录》等大量图文资料，在附录整理出与本文相关的 151 方战国古玺，为后续的研究提供参考。

This paper primarily investigates the chapter system of official seals from the Warring States period, finding that the chapter system of these seals exhibits both regional characteristics and commonalities. It proposes that the chapter system can serve as one of the criteria for classifying ancient seals by region. In recent years, with the excavation of a large amount of ancient seal materials, the study of ancient seal classification has become a current academic trend. The field of ancient script studies typically uses official positions, surnames, script styles, button designs, and auspicious language content as the main criteria for classification. This paper introduces a new method of classification, namely, through the examination of the chapter system to discuss its regional and common characteristics. Research has found that official seals from the Warring States period have uniqueness in specific chapter systems, such as unique facial styles and unique arrangements of character sequences, offering a significant area for exploration. This paper mainly discusses the official seals from four regions of the Warring States period: Qi, Chu, Yan, and the Three Jins, and is divided into three sections for an overview. First, it summarizes the situation of ancient seal classification, listing existing methods of classification. Second, it argues that the chapter system of official seals has regional characteristics, which can be demonstrated and analyzed from six different perspectives: "U" shaped arrangements, the placement of blank spaces, patterns of gathering and dispersing, facial styles, the arrangement of characters, and the usage positions of combined symbols. Third, the chapter system of official seals has commonalities; some regional official seals also exhibit this characteristic in the treatment of the same self-names in combined texts, which holds a certain research space. Currently, the style of ancient seal regional classification is not yet perfect, and there are still many ancient seals that are difficult to classify. The new method of classification can help solve this problem. Additionally, this paper uses a large amount of pictorial material from Ancient Seal Impressions and Record of Seals from Prosperous Times, and compiles 151 Warring States ancient seals related to this paper in the appendix to provide references for subsequent research.
