南极海底地名专名采词特征分析及规律研究OA

Antarctic undersea feature names form a core component of the identification system for polar geographic entities.Research on the naming rules of their constituent proper names carries significant implications for understanding the history of Antarctic exploration and scientific expeditions.However,existing scholarship lacks a systematic analysis of the patterns underpinning the lexical selection of proper names for Antarctic undersea features.In this study,we compiled a dataset of 313 Antarctic undersea feature names officially archived by the Scientific Committee on Antarctic Research(SCAR)and the Sub-Committee on Undersea Feature Names(SCUFN)up to 2025.Based on this dataset,we established a four-level classification system and a three-dimensional analytical framework:lexical selection features-linguistic ontological features-spatiotemporal evolution patterns.The findings reveal the following patterns:(1)For lexical selection,proper names are dominated by the humanistic and historical category,which accounts for 62.9％of the total samples.(2)For semantic attributes,nominal proper names are overwhelmingly dominant,accounting for 98.7％of all entries.(3)For structural characteristics,proper names consisting of three or more Chinese characters predominate,with a proportion as high as 86.3％.(4)For spatiotemporal distribution,the preference for lexical selection types exhibits a distinct transition from themes of early expedition commemoration to those of modern scientific research.Meanwhile,the lexical selection preferences of proper names in different sea areas are closely correlated with their respective exploration histories and geographical environments.This study provides a novel analytical perspective for subsequent research on Antarctic toponymy,and offers a scientific reference for China's participation in the governance of international undersea feature naming.
