Abstract: To support the safe utilization of contaminated construction land for redevelopment in Sichuan Province, this study conducted statistical analysis on the soil pollution characteristics of 1 075 closed and relocated construction land sites that completed soil pollution status surveys from 2017 to 2023 at the site and industry levels. The pollution load index (PLI) and systematic clustering method were adopted to characterize the risk based on the proportion of contaminated sites, the amount of pollution per unit area, and the comprehensive exceedance multiple. Meanwhile, the types of pollution, typical pollutants, the spatial distribution of exceedance and causes of pollution were statistically analyzed. The results showed that the top three industries in terms of the number of contaminated sites were Pb/Zn smelting, Pb/Zn mining, and Fe ore mining. Industries such as metal surface treatment and heat treatment processing, coking, and Pb/Zn smelting had more than 10 types of pollutants and a relatively high risk of soil pollution. The pollution types were mainly inorganic pollution, with As, Pb and Cr⁶⁺ being high-frequency pollutants (occurrence frequency greater than 30%).The areas with excessive pollution in contaminated sites were mainly distributed in material storage areas, production areas, sewage treatment areas, etc. This study reveals the risk coupling characteristics of "industry-pollutant-distribution area-source" in contaminated construction land plots in Sichuan Province. It is suggested that enterprises in industries such as metal surface treatment and heat treatment processing, Pb/Zn and ferroalloy smelting, As, Pb, Cr⁶⁺ and other pollutants, as well as key areas such as material storage areas, production areas and sewage treatment areas of enterprises be included in the list of key investigations and supervision, while adopting differentiated management models for contaminated construction land plots in different industries to optimize resource allocation and enhance the redevelopment and utilization of contaminated construction land sites.
