Song's Expansion and Relative Policies towards Shengdi (省地)
An Guolou;Shi Binbin;
As a regional geographical concept,the demarcation of Shengdi in Song Dynasty mainly applied to the frontier areas like Chuanxia( 川峡),Jinghu( 荆湖) and Guangxi( 广西) prefectures. The word Shengdi referred to the area under a stable jurisdiction by Song Court's prefecture or county.Outside of Shengdi,there existed numerous affiliated Jimi counties or scattered minority settlements,together with the unaffiliated Shengjie( 生界) areas. Song Court adopted differentiated policies or regulations for frontier affairs towards different areas and local people. The mid Northern Song Dynasty witnesses a further expansion of Shengdi,and the implementation of its administration model and relative transition policy. Many minority areas outside of Shengdi had been transformed from loose direct affiliation or other indirect affiliation, non-affiliation into direct control and administration. Based on the expansion and administration on Shengdi by Northern Song,the administrative efficiency on Shengdi in the south areas was continuously enhanced.
