【摘要】 元世祖忽必烈第七子奥鲁赤被封西平王，出镇吐蕃，开创了元朝治藏新格局。元成宗时期，奥鲁赤及其次子八的麻的加一支似乎移镇辽东，由其长子铁木儿不花一支镇戍吐蕃。除了铁木儿不花及其次子搠思班、孙党兀班、曾孙卜纳剌一系相继镇戍吐蕃外，其长子老的之子豫王阿剌忒纳失里也深度介入了治藏事务。他是搞垮元朝乌思藏格局的关键人物；在朵思麻地区，他力压镇西武靖王搠思班后裔，总揽大权。元亡后，阿剌忒纳失里所部南逃，可能与今天康北的霍尔巴人有历史渊源。更多还原

【Abstract】 Oqruch■,the seventh son of Qubilai khan,was granted Xi-ping Wang(西平王) and stationed in Tubo,which established a new pattern of Tubo governance in the Yuan Dynasty.During the Cheng Zong period,Oqruch■ and his second son Padma Dkhar,were re-stationed in Liaodong probably,and the Tubo-governing task was handed over to the eldest son Timar-buqd.In addition to Timūr-būqā and his second son C’os-dpal,grandson Tangut-dpal,great-grandson Prajna,his eldest son Lao-di’s son Aratnasiri,who was granted Yu Wang(豫王),also deeply involved in the governance of Tubo affairs.Aratnasiri was a key figure to disorder the Tubo governance of the Yuan Dynasty.In the area of Mdo-smad,he took over the power and suppressed the descendants of C’osdpal who was granted Zhenxi-wujing Wang(镇西武立靖王). After the fall of the Yuan dynasty,Aratnasiri fled to the south,and this may had a historical connection with the Hor-pa people in northern Mdo-khams area today.更多还原
