多功能被视为可持续城市排水系统（SUDS）的主要优势之一。它得到了科学研究和实践指南的推动。然而，不同利益之间的相互关系是模糊定义的，从而突出了缺乏在实际设计过程中如何促进它们的知识。在本研究中，我们借助情景分析来研究多功能性。芬兰图尔库市Kirstinpuisto的案例区设计了三个涉及不同范围的SUDS元素的雨水场景。之后，根据与多功能相关的四个标准（水量、水质、舒适性和生物多样性）对备选设计方案进行了评估。结果表明，多功能性可以在设计阶段本身进行分析，从而有意识地提供。然而，舒适性和生物多样性价值的评估较为复杂，且缺乏适当的方法。由于这四个标准是相互联系的，因此在景观设计中应该考虑多功能性，否则我们可能会失去一些与多功能性相关的好处。这加强了一种新兴的理解，即需要一种跨学科的方法将生态理解与系统思维结合到SUDS设计中，将它们不是作为单独的元素或处理列车的一部分，而是与城市景观的更广泛的社会生态框架联系起来。
Multifunctionality is seen as one of the key benefits delivered by sustainable urban drainage systems (SUDS). It has been promoted by both scientific research and practical guidelines. However, interrelations between different benefits are vaguely defined, thus highlighting a lack of knowledge on ways they could be promoted in the actual design process. In this research, multifunctionality has been studied with the help of scenario analysis. Three stormwater scenarios involving different range of SUDS elements have been designed for the case area of Kirstinpuisto in the city of Turku, Finland. Thereafter, the alternative design scenarios have been assessed with four criteria related to multifunctionality (water quantity, water quality, amenity, and biodiversity). The results showed that multifunctionality could be analyzed in the design phase itself, and thus provided knowingly. However, assessing amenity and biodiversity values is more complex and in addition, we still lack proper methods. As the four criteria have mutual interconnections, multifunctionality should be considered during the landscape architectural design, or else we could likely lose some benefits related to multifunctionality. This reinforces emerging understanding that an interdisciplinary approach is needed to combine ecological comprehension together with the system thinking into SUDS design, locating them not as individual elements or as a part of the treatment train, but in connection with wider social ecological framework of urban landscape.
