The identification of sites for locating new natural systems for wastewater treatment (NSWT), such as stabilization ponds and constructed wetlands, should combine multiple crucial factors (environmental, design, social and economic), and thus the implementation of multicriteria decision-making (MCDM) methods is required. In addition, the spatial nature of the site selection process necessitates the use of geographic information systems (GISs) because they are unanimously recognized as the most appropriate tool capable of supporting sophisticated spatial decision making. The resulting multicriteria spatial decision support systems (MC-SDSSs) provide a consistent framework for dealing with conflicting objectives while integrating the decision makers' (DMs') preferences in spatially related patterns/problems. A map-based, interactive UTAII implementation is presented, which provides a link between a well-understood decision support method and exploratory geographic visualization. Spatial UTA (S-UTA) is applied in a real case study concerning the ranking of candidate sites for implementing natural systems for wastewater treatment in the Evros-Rodopi prefectures of northeastern Greece. Finally, the obtained results are compared with those derived using other MCDM approaches to evaluate the performance of S-UTA in GIS-based land use suitability analyses.
确定用于废水处理（NSWT）的新自然系统（如稳定塘和人工湿地）的定位地点，应结合多个关键因素（环境、设计、社会和经济），因此需要实施多准则决策（MCDM）方法。此外，选址过程的空间性质需要使用地理信息系统（GIS），因为它们被公认为是最适合支持复杂空间决策的工具。由此产生的多准则空间决策支持系统（MC-SDSS）为处理冲突目标提供了一致的框架，同时将决策者（DM）的偏好整合到空间相关的模式/问题中。本文提出了一种基于地图的交互式 UTAII 实现方法，它在一个被广泛理解的决策支持方法和探索性地理可视化之间建立了联系。空间 UTA（S-UTA）应用于一个实际案例研究中，涉及在希腊东北部的埃夫罗斯-罗多彼省对实施废水自然处理系统的候选地点进行排名。最后，将获得的结果与使用其他 MCDM 方法得出的结果进行比较，以评估 S-UTA 在基于 GIS 的土地利用适宜性分析中的性能。
