西元2001年，位於宜蘭縣礁溪鄉的淇武蘭遺址因當地疏濬工程而被發現。同年，開始進行考古遺址的搶救發掘工作，至西元2003年發掘結束，遺址開挖面積共計約3,814平方公尺。其考古資料在歷經數年的處理之後，於西元2008年完成發掘報告。此外，亦有為數不少的相關研究論文發表。淇武蘭遺址的發掘資料，對於歷史、族群與考古研究等領域皆有相當的重要性，尤其是這些資料皆出自地層中最真實且原始的堆積，留有完整的脈絡資訊以為依據。目前認為該遺址屬過去的噶瑪蘭族群所遺留，可確定之較早年代至少達600年前，但很可能尚可追溯及1,500年前。本文根據考古出土證據，復原與探討當時之飲食生活，主要資料來自考古發掘所出土的相關考古遺留，但因本時代已涉及文字歷史階段，故亦從文獻中尋得若干相輔證據。

The Qiwulan Site, located in Jiaoxi township in Yilan county, was discovered in 2001 during public works construction connected with clearing a drainage channel. Salvage excavation was immediately undertaken. By the end of the project in 2003, a total of 3,814 m^2 area had been excavated. It took several years to analyze the archaeological data from the site and complete the excavation report in 2008. Several related research articles have also been produced. The excavated data from Qiwulan site is important for studies of history, ethnography and archaeology. The data discussed here was taken from the real and primary strata, where complete contexts of evidence had been preserved. The preliminary investigation indicates that the Qiwulan site contains the remains related to the Kavalan people. Its confirmed archaeometry points to at least 600 years ago, however the site history could be as early as 1,500 years ago. This study aims to reconstruct the traditional diets of that time according to the excavated data. The main research data for this study is archaeological remains, but historical documents are also used as complementary data.
