Abstract:

Since the Anthropocene epoch, the geopolitical environment in the South China Sea has become complex due to the involvement of neighboring and extraterritorial powers, and China's maritime rights and interests are constantly being restricted, squeezed and challenged. Starting from the geographical environment, geographical relationship and geographical structure of the natural and social gene subsystems, this paper divides three types of ancient-hereditary toponymic DNA, modern-variant toponymy DNA and modern-complex toponymy DNA from the logical starting point of placenames. A country-specific geo-environmental analysis framework for geographical names in the Nanhai Zhudao. The results showed that: 1) the names of the Nanhai Zhudao (South China Sea islands) were determined through the interaction of natural genetic and social genetic subsystems. 2) Considering cause-effect correlation, the source flow of the names of the Nanhai Zhudao from "owner-other-owner" led to the changes in genetics, mutation, and compounding in the transcription and expression of toponymic genes. For construction, the neighboring or extraterritorial powers used illegal means to build new geopolitical relationships for multilateral competition for maritime resources and maritime rights in the South China Sea. 3) The origin of the names of the Nanhai Zhudao was determined to be an interactive coupling process of spatial and material dominant genes and conceptual and historical evolutionary recessive genes in terms of gene transcription and expression..
