This invention discloses a method and system for calculating carbon emissions from contaminated site remediation based on multi-source data fusion, belonging to the field of environmental remediation and carbon management technology. The method includes: determining the system boundary for calculating carbon emissions from contaminated site remediation; identifying all potential carbon sources and potential carbon sinks within the system boundary; collecting activity data of potential carbon sources and calculating multi-dimensional carbon source emissions; when remediation technologies include phytoremediation, using the biomass method to calculate the technical carbon sink; analyzing the physicochemical properties of the site soil before and after remediation to calculate the soil carbon pool disturbance; and calculating the net carbon emissions from contaminated site remediation by coupling analysis of carbon sources and carbon sinks. This invention integrates three major carbon flows—"material and energy carbon sources," "technological carbon sinks," and "soil carbon pool disturbance"—into a unified calculation framework. By fusing multi-source data, it achieves accurate quantification of the net carbon effect of remediation activities, providing technical support for the green and low-carbon transformation of the contaminated site remediation industry.

A surface layer improvement system for on-site remediation of contaminated sediments includes: a stabilizer spray unit that performs underwater spraying of a stabilizer to a remediation target region; and a disturbing and mixing unit that induces bioturbation by mixing the stabilizer with the contaminated sediments in water. The disclosure performs the remediation of the contaminated sediments by spraying the stabilizer to the remediation target region of a water bottom floor through the stabilizer spray unit and performing on-site incorporation of the stabilizer sprayed through the disturbing and mixing unit.
