Redevelopment of large contaminated brownfields (megasites) is often hampered by a lack of communication and harmonization among diverse stakeholders with potentially conflicting interests. Decision support is required to provide integrative yet transparent evaluation of often complex spatial information to stakeholders with different areas of expertise. It is considered crucial for successful redevelopment to identify a shared vision of how the respective contaminated site could be remediated and redeveloped. We describe a framework of assessment methods and models that analyzes and visualizes site- and land use-specific spatial information at the screening level, with the aim to support the derivation of recommendable land use layouts and to initiate further and more detailed planning. The framework integrates a GIS-based identification of areas to be remediated, an estimation of associated clean-up costs, a spatially explicit market value appraisal, and an assessment of the planned future land use's contribution to sustainable urban and regional development. Case study results show that derived options are potentially favorable in both a sustainability and an economic sense and that iterative re-planning is facilitated by the evaluation and visualization of economic, ecological and socio-economic aspects. The framework supports an efficient early judgment about whether and how abandoned land may be assigned a sustainable and marketable land use.
大型污染棕地（megasites）的再开发常常受到不同利益相关者之间沟通不畅和协调不足的阻碍，这些利益相关者可能存在利益冲突。需要决策支持来为具有不同专业领域的利益相关者提供综合而透明的评估，以评估通常复杂的空间信息。成功的再开发需要确定一个共同的愿景，即如何对各自的污染场地进行修复和再开发。我们描述了一个评估方法和模型的框架，该框架在筛选层面分析和可视化特定于场地和土地利用的空间信息，旨在支持可推荐的土地利用布局的制定，并启动进一步和更详细的规划。该框架集成了基于 GIS 的待修复区域识别、相关清理成本估算、空间明确的市场价值评估，以及对规划未来土地利用对可持续城市和区域发展的贡献的评估。案例研究结果表明，衍生选项在可持续性和经济性方面都具有潜在的优势，并且通过评估和可视化经济、生态和社会经济方面，迭代规划变得更加容易。该框架支持对废弃土地是否以及如何可以指定可持续和有市场价值的土地利用进行有效的早期判断。
