岷州总管府辖区盈缩与唐和吐谷浑关系考察

An Investigation on the Expansion and Shrinkage of the Minzhou General Administration Office and the Relationship Between Tang and Tuyuhun

岷州总管府是唐与吐谷浑从合作走向冲突的产物。武德时期,其辖区由北向南扩大,是吐攻唐守的结果。唐廷旨在建立以岷州为节点连接洮水、羌水流域各州和以武州为节点连接羌水、白水流域各州的防御网络,以保护长安至西域的渭河谷地通道和益州至长安的散关道。贞观年间,其辖区从南向北、从西向东缩小。缩小岷州都督府(由总管府演变而成)辖区,并与松州都督府地域分工,唐廷得以招抚党项,更迭吐谷浑。此辖区盈缩、彼此攻守的形势表明唐、吐关系只能是暂时合作,冲突才是主旋律。

The Minzhou Zongguanfu(General Administration Office)was the product of the deteriorating of the relationship between Tang and Tuyuhun which was moving from cooperation to conflict.During the Wude period,the jurisdiction of the governor\s government expanded from north to south,reflecting the Tang defense strategy in the face of the aggressions from the Tuyuhun.By expanding the jurisdiction of the Minzhou General Administration Office,the Tang Dynasty first established a linkage between the prefectures in the Taoshui and Qiangshui basin with Minzhou as the pivot to protect the Weihe Valley passage from Chang\an to the Western Regions.Subsequently,a Wuzhou node was established to connect theprefectures in the Qiangshui and Baishui basins to protect the Sanguan Road from Yizhou to Chang\an.During the Zhenguan period,its jurisdiction shrank from south to north and east to west in accordance with Tang\s military advances.By reducing the area under the jurisdiction of the Minzhou Dudufu(succeeding the Zongguanfu)and the division of territory with the Songzhou Dudufu,the Tang could focus on pacifyng the Tangut and regime change of the Tuyuhun.Behind this expansion and shrinkage of jurisdiction hides the irreconcilable conflict between Tang and Tuyuhun over border security,which proved to be the norm rather than the temporary cooperation.
