Mapping Practice of Nanjing Toponym Cultural Map from the Perspective of Genes
Rich and profound toponymic resources have been accumulated in Nanjing in its long urban development history,and the research on the inheritance and preservation of Nan-jing's toponymic culture has received extensive attention.Based on the theory of cultural gene,we carry out the map-ping work of Nanjing's toponymy culture from three aspects:the extraction of toponymy cultural gene elements,the classifi-cation of element levels and the expression of mapping.First-ly,we couple toponymy and gene theory,introduce toponym-ic entity cultural genes and toponymic word cultural genes,de-construct and extract Nanjing's toponymic cultural genetic ele-ments to provide cartographic elements for the map.Second-ly,in order to realize the hierarchical classification of carto-graphic elements,the preliminary classification of cartograph-ic elements is carried out from the qualitative perspective of"macro-meso-micro",and then the entropy weight method is used to quantitatively score the micro-toponym individuals.Finally,the toponymic culture map of Nanjing is realized via paper media with electronic media by using map design theory and interactive technology.This research introduces multidis-ciplinary theories,methods and technologies into the mapping practice of Nanjing toponymic culture map,in order to better inherit Nanjing toponymic culture,promote toponymic re-search,and provide new ideas for Nanjing toponymic culture mapping.
