基于更路簿多抄本互证的南沙渔场作业空间重构OACHSSCD

Drawing upon 832 original entries from five Genglubu(traditional Chinese sea route records)manuscripts authored by Wang Guochang,Xu Hongfu,Liang Qirui,Mai Xingxian,and Li Genshen,218 fishing production routes covering 75 islands and reefs in the Nansha Islands were extracted through core text screening and three-tiered data integration.Breaking away from the traditional analytical framework of linear routes such as the"Dongtouxian,"a"Four Zones in One"spatial framework was constructed,thereby revealing the operational patterns of Hainan fishermen across the core zone(67 routes),eastern zone(51 routes),western zone(17 routes),southern zone(30 routes),and inter-zonal routes(53 routes).By integrating fishermen's oral histories with relevant literature,the production organization modes and adaptive strategies within each zone were analyzed.Through the establishment of a multi-source textual cross-verification mechanism,key nodes were calibrated across manuscript versions,and the dynamic evolution of fishermen's cognitive space was deciphered via an analysis of core routes and isolated routes.Cross-verification with He Jisheng's research results supplemented six critical routes,bringing the total number of reconstructed routes in the Nansha fishing grounds to 224,thus confirming the stability of the Hainan fishermen's geographical cognitive system regarding the Nansha fishing grounds.
