Study on the Spatial Distribution of Salt Place Names in Zigong City

This study takes 55 salt place names in Zigong City as the object, and explores their naming logic and distribution characteristics based on GIS spatial analysis and cultural landscape theory. The study found that the salt place name system includes natural landscape types (such as "Shenhai Well" and "Fuxi River") and cultural landscape types (such as "Sanduo Village" and "Xiqin Guild Hall"), and its spatial distribution presents a dual-core structure of "Ziliujing-Gongjing", forming a significant aggregation zone along the Weixi anticline geological structure and the Buxi River system. Natural place names are mostly distributed in the brine overflow area of the anticline axis, and cultural place names extend linearly along the ancient salt transport road in the Qing Dynasty. The semantic system of place names carries the memory of well salt technology (such as "Tianchepo" metaphor wooden well frame), resource competition narrative (such as the "Dengjingguan" name change event) and blessing cultural metaphor, forming a unique salt industry cultural landscape. The research results provide a new perspective for the protection of salt industry heritage and the construction of regional cultural identity.
