孙吴“限江自保”述论

Self-defence with the Changjiang River as the Barrier:National Defence Policy Implemented by the Kingdom of Wu

孙吴政权针对北方敌对政权采取的基本守国政策是"限江自保"。在军事上,"限江自保"即依托长江,而守在江北。孙吴荆州、扬州众多的"险要必争之地",实际反映了孙吴此项政策的具体实施情况。孙吴"限江自保"政策,为后来的东晋南朝政权所继承。

The national defence policy implemented by the Kingdom of Wu is to 'Self-defence with the Changjiang River as the barrier'. On the military affairs, the rulers of the Kingdom of Wu set their defence works to the north of the Changjiang River, in strategically important cities like Jinzhou and Yangzhou. This defence policy is inherited by Eastern Jin Dynasty, and Southem Dynasties.
