东晋京口—广陵战略格局的形成与演变

Formation and evolution of the strategic system of Jingkou and Guangling in the Eastern Jin Dynasty

东晋初,郗鉴以徐兖二州刺史身份从广陵移镇京口,同时都督青徐兖三州,这标志着京口—广陵战略格局的形成,长江南北被纳入同一军府管辖之中。东晋中期,由于京口与广陵各自承担不同的军事防卫任务,徐兖军府时镇京口、时镇广陵,京口—广陵一体化的格局便发展为防守京师镇京口、北伐进取则屯广陵。淝水之战前后,由于内部政局较为稳定,外部面临军事压力,广陵的战略地位明显上升。

At the beginning of the Eastern Jin Dynasty,Xi Jian,the governor of Xuzhou and Yanzhou,moved from Guangling to Jingkou and governed Qingzhou,Xuzhou and Yanzhou,which marked the formation of the strategic system of Jingkou and Guangling,and the north and south of the Yangtze River were under the jurisdiction of the same military government.In the middle of the Eastern Jin Dynasty,because Jingkou and Guangling undertook different military defense tasks,the government developed the system of the integration of Jingkou and Guangling:garrisoning Jingkou to guard the capital or stationing troops in Guangling for the Northern expedition.Before and after the Feishui War,due to the relatively stable internal political situation and the external military pressure,Guangling's strategic position increased significantly.
