Soil pollution risk control and remediation is the key to the safe use of constructed land. The effectiveness of this work is influenced by both technological development and environmental management, and the systematic and coherent linkage of supervision is crucial. National and local governments have made diverse attempts at the collaborative supervision of soil environments within constructed land. Utilizing local legislation, regulatory documents, and technical standards, these strategies have progressively honed and standardized the allocation of departmental responsibilities, process supervision, and access management, leading to effectively controlling the environmental risks of contaminated sites. Despite these advancements, there is a clear need for further bolstering the all-encompassing and interconnected nature of coordinated supervision. This thesis, based on the analysis of the natural attributes, socio-economic attributes, and soil remediation particularities of constructed land, systematically reviews the current status and typical issues of constructed land soil pollution risk control and remediation, and provides suggestions on optimization of collaborative supervision. Overall, within the framework of the national institutional system, local governments were focused on refining the scope of supervision, formulating implementation details, and strengthening supervision and implementation to meet national requirements, without imposing additional demands. In addition, the text analyzes issues such as unclear scope of joint supervision, insufficient planning considerations, shallow integration of land transfer, and inadequate integration of land plot information. It advances a suite of recommendations for enhancing the coordinated supervision framework, including clarifying supervisory scopes, alignment of land planning with soil remediation endeavors, specification of land transfer procedures, embracing a unified national land spatial "one map" strategy, and strengthening of oversight through a multiplicity of approaches. Future investigative trajectories may delve into the realms of precision regulation, pivot to green and low-carbon remediation methodologies, and digital transformation of soil pollution oversight, all aimed at significantly elevating the collective impact of coordinated supervision. This study offers valuable insights for enhancing the integrated regulatory framework for soil risk control and remediation on constructed land, thereby ensuring the safe and effective use of such land.
