優休牟涿國은 『三國志』 동이전 한組에 보이는 馬韓小國 中 하나이다. 그런데 이 小國의 規模나 社會性格, 經濟構造 等 모든 面에 對해서 밝혀진 것은 거의 없다. 이에 對해 接近할 수 있는 日次 方道는 位置 問題에서부터라 하겠는데 이것도 模糊한 狀態이다. 이러한 形便이기 때문에 優休牟涿國에 對한 硏究는 매우 어렵다. 다만 優休牟涿國 位置에 對해 富川地域度擧論되고 있어 旣往에 擧論된 優休牟涿國 位置에 對한 여러 설을 檢討하고 이를 通해서 富川과의 關聯 餘부를알아보았다. 그 結果 여러 說 中에서 李丙燾의 富川(富平)說은 如前히 有效한 見解임을 알 수 있었다. 『三國史記』 地理誌 富川地域 軍 이름인 主婦吐軍과 腸諸君을 통해서는 富川(富平·桂陽 包含)地域에 馬韓小國이 實在하였을 可能性을 알아보았다. 그 結果 優休牟涿國이 富川地域과 關聯이 있을 것으로 여겨졌다. 또한 國語學的으로 富川의 朝鮮時代 面 이름 中 하나인 鑄貨串面이 主婦吐軍과 連結되고 나아가 優休牟涿國果毅連結도 可能함을 알게 되었다. 한便 考古學的으로는 富川의 고강동遺跡이 注目되었다. 이 遺跡은 靑銅器時代 後期에서 初期철기時代의 것으로 富川地域 馬韓小國의 存在를 立證해 줄 資料로 생각되었다. 特히 이 遺跡의 幻軀遺構는 그 構造나 立地條件에서 宗敎儀禮와 關聯이 있는 것으로 馬韓 蘇塗의 原形으로까지 推定할 수 있다. 아울러 ‘主婦吐’名 기와가 發見된 桂陽山城度 持續的으로 注視해야 할 遺跡임은 勿論이다. 以上의 結果로써 본다면 現在의 富平·桂陽乙 包括하는 富川地域은 馬韓時代 政治體로서 小菊이 있었을 可能性이 짙다. 그 小菊은 優休牟涿國을 指目해 볼 수 있겠다.

Uhyumotakguk(優休牟?國) is one of the Mahan(馬韓) countries seen in the Section for East Barbarians(東夷傳) of the 『Samgukji(三國志)』. However, little is known about the size, social characteristics, and economic structure of this small country. The first way to approach this is a matter of location, but this is also ambiguous. Because of these circumstances, it is very difficult to study the Uhyumotakguk. However, since the Bucheon(富川) region is also mentioned about the location of the Uhyumotakguk, various theories about the location of the Uhyumotakguk mentioned earlier were reviewed. Through this, this study investigated whether it was related to Bucheon. As a result, it was found that, among many theories, Lee Byung-do(李丙燾)’s Bucheon(Bupyeong：富平) theory was still valid. We investigated the possibility of the existence of Mahan in the Bucheon region through Jubuto-gun(主夫吐郡) and Jangje-gun(長堤郡), which are the names of the Bucheon region(including Bupyeong and Gyeyang(桂陽)) in the 『Samguksagi(三國史記)』 jiriji(地理志). As a result, it was found that Uhyumotakguk would establish a relationship with the Bucheon region. In addition, it was found that Juhwagot-myeon(注火串面), one of the names of myeons in Bucheon during the Joseon (朝鮮) Dynasty, was connected to Jubuto-gun, and furthermore, it was possible to connect with Uhyumotakguk. On the other hand, archaeologically, the Gogang-dong(古康洞) ruins in Bucheon drew attention. These ruins are dated from the late Bronze Age to the early Iron Age, and were thought to prove the existence of Mahan in Bucheon. In particular, the Hwankuyugu(環溝遺構) of this site is related to religious ceremonies in terms of their structure and spatial conditions, and can be estimated as the original form of Mahan Sodo(蘇塗). In addition, Gyeyang-mountain Fortress, where a tile with the name ‘Jubuto’ was discovered, is of course also a site to keep an eye on. Judging from the above results, it is highly probable that the present Bucheon area, which includes Bupyeong and Gyeyang, had a small country as a political body during the Mahan period. That small country can be pointed out as the Uhyumotakguk
