南北朝在分裂对峙中存在着正统争夺和文化争胜的情况,多认为北朝因占据中原而具有地理上的正统优势,而南朝处于下风。北朝通过孝文帝迁都改制、军国文书的措施,逐渐建立起中原地理正统论,并在南北外交场合中多次使用。南朝则利用种族上的正统优势,将北方的地理元素与胡族相联系,并用江南的自然环境和物产与胡族色彩浓厚的风土物产拉开距离。 In the separatist confrontation, there existed a situation of orthodox competition and cultural victories in the North and South Dynasties. Many believed that the North had a geographical orthodox advantage over the Central Plains while the South was in a disadvantage. Through the measures taken by Xiaowen Emperor to relocate the capital and military instruments, the Northern Dynasties gradually established the orthodox geography of the Central Plains and used it repeatedly in the diplomatic occasions between North and South. The Southern Dynasties used the ethnic orthodox superiority to link the geographical elements of the north with the Hu tribes and to distance themselves from the rich natural and terroir property of the Hu ethnicity with the natural environment and properties in the south.
