珠江口“貿易（諸）島（Ilha(s) da B(v)eniaga）”蠡探：位置與名移

This study delves into the historical transformation and geographical positioning of the “Trade Islands” (Ilha(s) da B(v)eniaga) located at the Pearl River Estuary. The term, which has been a staple in Portuguese documentation since the mid-16^th century, signifies the initial point of contact and commerce between Portugal and China, an event of pivotal significance in the annals of Sino-foreign relations. Through a meticulous analysis of historical Portuguese records, navigational maps, and pertinent literature, this paper uncovers the exact location of the “Trade Islands” and traces the evolution of their nomenclature. The findings indicate that the term initially denoted Chek Lap Kok Island, with the designation eventually transitioning to Ladrone Island over the years. This shift mirrors the reorientation of Macao’s eastward trade routes and the emergence of Macao as a burgeoning trade hub. Additionally, the paper explores the broader implications of the “Trade Island” concept within Portuguese maritime geography and reviews the historical significance of various trade islands dotting the Guangdong coastline.
