Research on the Protection and Reuse of Third-Line Industrial Relics Based on GIS Spatial Analysis: A Case Study of Zigong Electric Welding Electrode Factory

Under the new situation of accelerating the high-quality development of old industrial cities in China, industrial heritage, as an important material carrier of China’s industrial culture, carries the appearance and memory of the times of different historical development stages of the city, and is the main component element of urban culture. With the passage of time, the traditional industries that once promoted urban development have gradually moved to the urban core, and the old factory sites have decayed and been abandoned, resulting in disconnection with urban development and waste of urban land resources. As an important stock resource, how to better radiate the surrounding areas, promote industrial transformation and drive urban rejuvenation through protection and reuse is an important part of the research on industrial heritage. This paper comprehensively uses POI data kernel density analysis and SWOT analysis model, takes Zigong welding electrode factory as the research object, focuses on analyzing the advantages, disadvantages, opportunities and threats faced in the development of third-tier industrial remains, and provides strategic suggestions for the reuse of urban industrial relics at the planning level.
