齊魯、膠遼官話是現代漢語鼻音韻尾音變的指標區域，展現在「中古咸山同讀、深臻同讀，且多讀為鼻化韻」，不同於一般漢語方言由咸山宕攝率先發生鼻化的模式。本文從鼻音語音性質的探討出發，藉語言類型學的觀點離析漢語鼻尾格局；接著梳理古齊魯地區的歷時鼻尾變異語料，企圖聯繫歷時文獻及現代方言，探討齊魯、膠遼官話區的鼻尾音變歷程。本文主要成果有四點：（1）藉鼻音性質與音變模式的探討，提出鼻尾變異的三個主要類型：[m] 韻尾保存型、[n]、[ŋ] 韻尾對立型、簡化鼻尾型。（2）對漢語方言鼻尾音變劇烈的冀魯、膠遼官話進行細部的鼻尾類型分析，並闡述建立鼻尾格局「山東型」的意義。（3）聯繫古今語料，指出先秦古齊魯地區「齊人殷聲如衣」的鼻尾弱化方音特色，並分析今冀魯、膠遼官話梗曾通宕江攝的白讀層鼻化韻。（4）指出現代冀魯、膠遼官話最具指標性的前鼻尾韻弱化現象是晚期音變的結果。

　　Qilu and Jiaoliao dialect are areas of syllable-final nasal mergers and nasalization in modern Chinese. This article starts from the discussion of the nasal phonology, and uses the viewpoints and methods of linguistic typology to sort out the sinister variants in pre-Qinlu region. While there is already established research methodology on the topic of “Variation Phenomenon of Chinese Nasal Endings,” this thesis aims to provide more meticulous exploration of the phonetic variation patterns and evolution of Chinese nasal endings through discussion of the characteristics of nasal endings as well as linguistic typology perspectives and methodology.
　　The topics and results discussed in this thesis are as follows：(1) Discussion of the influence of “nasal characteristics” on the structure and typological evolution of Chinese nasal endings. (2) In-depth analysis of the two main phonetic change effects for nasal endings： “nasal ending weakening” and “nasal ending merging”. (3) The three main types of Chinese nasal ending phonetic structures： remnant forms of [m] endings, [n] and [ŋ] contrast ending structures, simplified nasal ending structures. (4) Contacting the ancient and modern languages and pointing out that the characteristics of the “Qi Ren Yin Sheng Ru Yi” in the ancient Qinshui region of the pre-Qin period.
