刘裕在京口起兵成为宰辅后对藩镇做了一系列政策调整，改变了东晋以来以权臣镇守要藩的传统，初步形成了“皇子守要藩”的政治格局。为防止幕僚专制地方，刘裕在为出守藩镇的子弟配以文武僚佐时，十分注意幕僚之间的相互制约，同时，关中的得而复失使得刘裕认识到藩镇僚佐之间相互掣肘的危险性，故而开始转变藩镇政策，湘州的复设意味着刘宋开始走向分割藩镇以削弱地方势力的道路。

After rising to power in Jingkou and becoming a prime minister,Liu Yu implemented a series of policy adjustments to fanzhen( military-governing areas),altering the Eastern Jin tradition of having powerful ministers guard strategic regions and initially forming the political pattern of “imperial princes guarding key regions”. To prevent officials from monopolizing local power,Liu paid great attention to ensuring checks and balances among the civil and military aides assigned to the princes governing these regions. Meanwhile,the loss of the Guanzhong region after its brief recovery made Liu Yu aware of the dangers of internal friction among aides,thus prompting a shift in his fanzhen policy. The reestablishment of Xiangzhou marked the beginning of the Liu Song dynasty's approach of dividing fanzhen to weaken local powers.
