梁武帝置州政策——地域配置、人事安排與國家制度

The Provincial Establishment Policies of Emperor Wu of Liang: Territorial Organization, Personnel Management, and State Institutional Transformation

梁武帝（464-549，502-549在位）統治期間大量置州，州數量大幅增長四倍餘。細究其置州地域與歷史脈絡可知，新置州的地域集中在江淮地區以及對北戰事的新拓地帶、荊楚地區、巴蜀與漢水谷地與嶺南地區。觀察這些新置州較密集的區域，可知在江淮與北境新拓區域，可說受到北魏改鎮為州，以及宋齊以來將淮北四州州鎮化的影響。荊楚地區方面，新置州多集中在蠻人所居之地，可說是左郡左縣政策的延續。巴蜀與漢水谷地和同時受到州鎮化與拉攏在地豪族與蠻酋有關。嶺南地區則與蕭梁保障嶺南交通線有關，另也為籠絡當地俚獠人群而立州於其勢力範圍。
至於都督區與所領州的部分，許多新置州並未包含在都督區內。以中大同元年（546）為準，都督區所包含之州僅佔全體109州中的61州，比例只有56%。新置的87州中只有39州被納入都督區管轄，只佔45%。至於新置州刺史的人事任用，北境軍鎮部分可見其相當程度與附近重要州鎮刺史的軍府幕僚或將領、親屬出身，此種人事安排其實仍和前代以重要軍府作為人事任用的主要來源基本相同。荊楚、巴蜀等地區亦可見通過荊州、益州兩大軍府任用人事的狀況。至於蠻地州多半以蠻酋為刺史。嶺南地區大部分的新置州分布在交通沿線，也有任用當地蠻酋為刺史的案例。
蕭梁的行政區改制可說與南北朝當時的軍政背景與國制改革的進行相關。南朝在失卻淮北地後於緣淮一帶復置淮北四州，並在與北魏間的軍事衝突中失卻豫、司、梁等要州，迫使南朝另置州鎮於內地，開啟南朝州鎮化的先聲。北魏在五世紀後期將南方軍鎮改制為州，又北魏積極招撫蠻酋為刺史。蕭梁在對北戰事得利後也延續北朝建置，同時也通過刺史職吸收蠻酋。與此同時，蕭梁將州依規模、位秩分為五等，但仍有不少新州不在《隋書•百官志》中所見官序。州佐在天監官制改革後被納入中央官序，為中央控制州佐人事創造條件，一方面能強化國家對地方社會的控制，二方面也實現「官＝士」的國家官制秩序。總此，梁武帝廣置新州，係因應當時的軍政情勢，同時服務於軍事防禦、與其他族群的聯合，以及配合國家整體官制改革等多重目標。

During the reign of Emperor Wu of Liang (464–549; r. 502–549), the number of provinces (zhou州) increased dramatically, expanding to more than four times its previous scale. A closer examination of the geographical distribution and historical context of these newly established provinces reveals clear regional patterns. New provinces were concentrated primarily in the Jiang–Huai江淮region and newly acquired northern frontier zones, the Jing–Chu荊楚area, the Sichuan四川Basin and Han River漢水valley, and the Lingnan嶺南region.
In the Jiang–Huai region and the newly expanded northern frontier, the establishment of new provinces was influenced both by Northern Wei policies of converting military garrisons into provinces and by the“province-garrisonization”州鎮化of the four Huai-north淮北provinces since the Liu Song劉宋and Southern Qi南齊periods. In the Jing–Chu region, newly established provinces were largely concentrated in areas inhabited by non-Han populations, reflecting the continuation of the zuojun zuoxian左郡左縣(left-hand commanderies and counties) policy. In the Sichuan Basin and Han River valley, provincial establishment was shaped by both province-garrisonization and efforts to co-opt local elite lineages and tribal leaders. In Lingnan, the creation of new provinces was closely tied to securing transportation routes, while also serving to incorporate Li俚and Liao獠populations by establishing provinces within their spheres of influence.
With regard to the relationship between dudu都督(regional command) districts and their subordinate provinces, many newly established provinces were not incorporated into dudu jurisdictions. As of 546, only 61 of the empire’s 109 provinces—approximately 56 percent—were included within dudu districts. Among the 87 newly established provinces, only 39 (45 percent) fell under dudu administration.
Personnel appointments to newly established provincial governorships further reflect these regional distinctions. In the northern frontier garrison provinces, governors were frequently drawn from the military staffs, commanders, or kin networks of neighboring major provincial or garrison authorities, continuing earlier patterns in which major military headquarters served as the primary reservoir for official appointments. Similar practices can be observed in the Jing–Chu and Sichuan regions, where appointments were mediated through the major military commands of Jingzhou荊州and Yizhou益州. In provinces established in non-Han areas, local tribal leaders were often appointed as governors. In Lingnan, newly created provinces were largely situated along transportation corridors, and appointments of local tribal leaders as governors can likewise be observed.
Administrative reorganization under the Liang dynasty should be understood within the broader context of the political and military background and state institutional reforms during the Northern and Southern Dynasties. After losing Huai-north area and Yu豫, Su司and Liang梁provinces following the defeat by the Northern Wei, the Southern Dynasty reestablished these provinces on the garrisons, marked the beginning of province-garrisonization. In the late fifth century, the Northern Wei converted southern military garrisons into provinces and actively recruited tribal leaders as provincial governors. Following military successes against the north, the Liang dynasty adopted similar practices, both continuing northern institutional models and incorporating tribal leaders through provincial governorships. At the same time, the Liang court classified provinces into five grades based on scale and official rank. Nevertheless, many newly established provinces did not correspond to the official hierarchies recorded in the“Treatise on Officials”in the History of Sui. After the Tianjian天監reforms, however, subordinate provincial officials were incorporated into the central bureaucratic ranking system, enabling greater central control over provincial personnel. This reform not only strengthened state oversight of local society but also advanced a bureaucratic order in which official status and elite identity became institutionally unified. In sum, the provincial establishment policies of Emperor Wu of Liang were made in response to military and political circumstances, in order to strengthen defense, facilitate alliances with non-Han groups, and advance comprehensive reforms of the state administrative system.
