乌程汉简是浙江湖州首次出土的简牍，其出土填补了浙江地区未曾发现简牍的空白，对研究浙江汉代相关历史具有十分重要的价值。从书法史的角度看，乌程汉简的字体涵盖多种类型，且其书风美学价值丰富，为研究两汉时期的书体演变及其书风多样化提供了新材料。学界针对乌程汉简的相关研究，仍未充分展开，在多个方面还存在着进一步研究的空间。 本文分四个篇章展开论述。第一章概述乌程汉简出土情况、形制与内容。第二章对乌程汉简的篆书、古隶、汉隶正体、新隶体、草书五种字体进行分类和书风解析，发现其各体特征明显，风格面貌迥异。第三章基于目前学界对于新隶体的研究较为驳杂的情况，笔者首次对乌程汉简的新隶体风格具体分型，把乌程汉简中所包含的新隶体分为普通型、进阶型两大类，其进阶型中楷化初现类、行笔勾连类为新隶体的流变现象提供了丰富的佐证材料。此分型方法似对文字学中新隶体的研究具有一定的借鉴作用。第四章将乌程汉简与长沙走马楼吴简、郴州苏仙桥吴简进行字体及书风对比，以及从乌程汉简 185 号“吴库”二字入手，探讨了乌程汉简中存在吴简的可能性，并进一步提出乌程汉简年代下限可达三国时期的猜想。

Wucheng Han Bamboo Slips are the first bamboo slips unearthed in Huzhou, Zhejiang. Its unearthed fills the gap that no bamboo slips have been found in Zhejiang, and is of great value to the study of the related history of the Han Dynasty in Zhejiang. From the perspective of calligraphy history, the fonts of Wucheng Han bamboo slips cover a variety of types, and its style of calligraphy is rich in aesthetic value, which provides new materials for the study of the evolution of calligraphy styles and the diversification of calligraphy styles in the Han Dynasty. The relevant research on Wucheng Han Bamboo Slips has not been fully developed in the academic circle, and there is still room for further research in many aspects. This dissertation is divided into four chapters. The first chapter summarizes the unearthed situation, shape and content of Wucheng Han bamboo slips. The second chapter classifies and analyzes five fonts of seal script, ancient official script, official script, new official script and cursive script of Wucheng Han bamboo slips, and finds that each font has obvious characteristics and different styles and appearances. The third chapter is based on the fact that the research on the new official style in the current academic circle is relatively heterogeneous. For the first time, the author specifically classifies the new official style of Wucheng Han bamboo slips, and divides the new official style contained in Wucheng Han bamboo slips into two types: ordinary type and advanced type. The big category, its advanced type, the early emergence of the Chinese Kaihua type, and the running-bi hook-linked type, provide rich supporting materials for the rheological phenomenon of the new official style. This classification method seems to have a certain reference function for the study of new official script in philology. The fourth chapter compares Wucheng Han bamboo slips with Changsha Zoumalou Wu bamboo slips and Chenzhou Suxianqiao Wu bamboo slips in terms of font and calligraphy style, and discusses the possibility of Wu Cheng Han bamboo slips in Wucheng Han bamboo slips starting from the word "Wu Ku" in No. 185 of Wucheng Han bamboo slips nature, and further put forward the conjecture that the lower limit of Wucheng Han bamboo slips can reach the period of the Three Kingdoms.
