本文在有限度战争的理论指导下,对宋辽围绕着北汉存亡的军事冲突进行了考察,认为由于北汉的存在,宋辽近二十年的军事冲突并没有呈现辗转升级的线性发展态势,而是在有限政治目标下显得较为克制,河东地区充当了缓冲地带的作用。但是,随着北汉的灭亡,双方的有限目标的政治内容已不复存在,宋辽关系出现较大的波动,双方战争全面爆发。 Under the guidance of the theory of limited warfare, this paper examines the military conflicts surrounding the existence of the Northern Song Dynasty between Song and Liao, and concludes that due to the existence of the Northern Han Dynasty, the military conflicts in the Song and Liao Dynasties have not shown a linear trend of development. , But appears to be more restrained under the limited political goals. The Hedong region serves as a buffer zone. However, with the demise of the North Han Dynasty, the political content of the limited objectives of both sides ceased to exist and the relations between the two countries witnessed greater volatility. The war between the two sides broke out in full swing.
