From top-level design to practice path:enlightenment based on the research of contaminated sites risk management and reuse system in the UK and the US
Top-level design features of contaminated sites risk management and reuse systems in the UK and the US were summarized,including the basic concepts,law and policies,cross-department cooperation,and their practice path thus was extracted.After fully learning the international experience,based on China's work foundation,a"begin with the end"top-level design optimization suggestion,a"divide and management"site classification system and a"parallel flow process"practice path construction strategies were proposed,including enacting laws and policies related to the future land use planning of contaminated sites,breaking down land use and contamination data barriers,constructing a classified site management system,developing practice guidelines for contaminated sites risk management and reuse,and establishing a collaborative decision-making mechanism for the entire process.These conclusions could provide a reference for the formulation of relevant policies on risk management and reuse systems of contaminated sites in China.
