作为中国传统祭祀节日之一的七月十五，处于下半年的第一个月圆之夜，历来被人们所重视。本文将关注重心集中于一个北方鲁中村落的田野调查。论文以本人2011-2013年在山东省莱芜市颜庄村的个案调查为例，使用历史民俗学的研究方法，通过对当地村落宗族家谱文献、村落内现存碑刻及其他史志文字资料搜集整理，加之对该地进行较为深入的田野调查访谈的基础上，尽可能真实、全面地展现颜庄村家族式七月十五的仪式过程和民俗特征，力求为七月十五在北方的研究提供一份较为详实的田野个案。全文共分三部分，首设绪论，末置附录，正文三章。第一章，颜庄村的地理环境与人文资源，说明颜庄村的地理位置、生态环境、村落人文景观的变迁以及村民的信仰传统与岁时传统。第二章，颜庄村七月十五节俗传统及仪式分析，通过将地方志资料、村民口述资料、节日传说与田野调查获得仪式现场资料整合，从村民记忆中的七月十五和现存仪式中的七月十五两个方面切入，对其在当地的历史渊源和“祖先在场”的仪式过程进行探讨。注意对仪式细节的描写。第三章，村落岁时生活中的祖先祭祀，把七月十五放入当地村落岁时生活序列中，围绕此节日展开对家族社会生活及村民祖先崇拜信仰的讨论。除此之外，关注行政区划、自然区域和形成节日文化认同三者之间的区别和重合，以及分析七月十五在当地的传承与变迁。本文的主要观点是，传统鲁中村落生活中的七月十五节日，存在于当地村落岁时结构与村民岁时观念之中，调节和整合家族、社会以及民众民俗信仰、生死观念等。通过对当地七月十五内在因素与外部条件分析，探讨当地民众的时间观念和村落家族内部结构，比较真实地还原一个鲁中村落村民的岁时生活，并对由现代化带来的节日传承与变迁问题进行简要思考，为北方七月十五节日研究提供村落家族调查个案。

July 15th is one of the three Ghost Festivals in China. Throughout the ages Chinese people have always paid a great deal of attention to this festival, which is also called ‘The Hungry Ghost Festival’ (Ullambana by Buddhism and Zhongyuan Festival by Taoism). However, in the middle region of the Shandong Province, there is a group of people who simply name this festival ‘July 15th’. These people hold an ancestral rites ceremony at the same time each year.This thesis is based on the author’s fieldwork from 2011 to 2013 in the Yan Zhuang village. In addition to the introduction, conclusion and the appendix, there are three chapters in this study. In chapter one, the thesis provides the village's background and family life. In chapter two, the author describes the local villagers' memory of the ‘July 15th’ Festival and the existing details of the festival ceremony and other local customs in ‘July 15th’. In the last chapter, the author focuses on the ancestor worship in the local village life of traditional festival.From the historical literature as well as the local literature of the village and existing inscriptions through participant observation, together with the author’s interviewing of the villagers about the July 15th festival legends, the author discovers the villagers believe in ancestor worship. All activities center around the family and the ‘July 15th’ festival becomes a new cultural identity range. This has helped readers to understand better the villages’ concept of time and their very strong family structure.In the past most of the surveys on this ‘July 15th’ festival have been conducted in South China. This paper tries to show that the festival is highly regarded as a very important and family festival in North China. Ancestors presence is a kind of performance of ancestors recognition and lineage consociation.
