The transformation of inefficient industrial & productive land (IIPL) in urban centers and surrounding areas is a crucial component of stock planning and urban renewal in megacities. From the perspective of environmental risk, both national and local governments have gradually established and refined a 'full life-cycle' environmental management process. Through a review and analysis of current research, this study summarizes the current status of soil environmental quality in a central urban area of Shanghai, reveals its relationship with historical land use, and establishes a risk assessment model for the soil environmental quality of IIPR in the central urban area. According to different risk levels and the current status of IIPR in central urban areas, a technical framework has been formulated for land planning and banking. For high-risk land parcels that require urgent treatment, a green governance strategy has been proposed such as the 'environmental remediation+' model. This approach integrates remediation with development needs, minimizing redundant excavation and backfilling, thereby reducing costs. A tailored remediation plan, 'One Parcel, One Policy' was introduced to ensure rational planning and efficient reuse of land, promoting urban renewal and the resource-efficient utilization. The results of this study provide significant insights for soil environmental management in megacities.
