东吴、东晋、宋、齐、梁、陈六个朝代曾盛极一时,政治、经济、文化等多方面均达到了中国古代社会发展史的一个高峰。南京玄武湖由于其地理位置的特殊性见证了六朝的由鼎盛到衰败的历史。本文通过对六朝时期南京玄武湖的自然演化和人工改造.以及周边皇家园林的历史演变进行考证,研究玄武湖及其周边皇家园林对六朝都城格局变化的影响及其重要作用。 The six dynasties of Soochow, Eastern Jin, Song, Qi, Liang and Chen once flourished, reaching a peak in the history of ancient Chinese society in politics, economy and culture. Nanjing Xuanwu Lake witnessed the history of decline and decline of the Six Dynasties due to its particular geographical location. Through the research on the natural evolution and artificial transformation of Xuanwu Lake in Nanjing during the Six Dynasties period and the historical evolution of the imperial gardens in the vicinity of the Six Dynasties, this paper studies the influence of the Xuanwu Lake and its surrounding imperial gardens on the pattern changes of the capital cities in the Six Dynasties and their important roles.
