「南方」是章太炎對中國政治的地緣理解中一層重要維度，而武昌則是除太炎生長於茲的江浙以外支撐其南方圖景的突出一極。章太炎的武昌情結發端於早年的經史考據，又在太炎走出書齋後引導他與共進會等華中革命勢力漸趨合流。此一思想與環境的互動，正是他1911年後尊奉黎元洪等一系列政治選擇的動因。二次革命後，以武昌情結為中心的南方圖景構建同時成為章太炎疏通民族主義觀念與重塑現代中國政治統緒的思想模型，並貫穿於他在護法運動與聯省自治中的政治實踐。承載於南方觀念的建國方略及其調適而上遂的歷程，提供了一個展示近代地方空間之多元性，以及清末革命本土思想資源與二十世紀後續民族民主革命之連續性的生動案例。

“South” was an important dimension of Zhang Taiyan’s 章太炎 (1869-1936) geopolitical understanding of Chinese politics, and Wuchang served as a prominent pole that supported his southern landscape along with Jiangsu and his hometown of Zhejiang. Zhang’s“ Wuchang complex” had originated from his early historical textual criticisms, and after devoting himself to the revolution, it gradually led him to converge with revolutionary forces in central China, especially with the Progressive Association 共進會. This interaction between thought and environment was precisely the motivation for his series of political choices following 1911, including his reverence for Li Yuanhong 黎元洪 (1864- 1928). After the Second Revolution in 1913, the construction of the southern landscape, centered on the Wuchang complex, became Zhang’s ideological model for revising the concept of nationalism and reshaping the political system of modern China, ultimately permeating his political practices for the rest of his life. The nation-building strategy embodied in the notion of “south” and its processes of adaptation and evolution provide a vivid case that shows the diversity of modern local spaces as well as the continuity from local ideological resources of the revolution in the late Qing dynasty to the later national-democratic revolution of the 20th century.
