智能技术承诺采用创新方法来管理基于自然的解决方案（NBS），以便在气候变化下发挥更有效的调节功能。然而，智能系统也可能通过引入城市景观的显著变化来影响人们对NBS的体验。本研究调查了公众对“智能”蓄水池的看法，这些蓄水池的水位变化由智能系统控制，并在规划和设计选择确定的以下微尺度景观元素中变化：土地利用背景，流域坡度和周围植物。使用可视化，显示池塘景观设计方案在典型的，低（排水），高（蓄水）水位，我们调查了居民在三个美国城市的智能池塘（n = 974）的看法。我们的研究结果表明，智能系统的水位操纵会对雨水池的感知产生负面影响;低水位和高水位都被认为比典型的水位条件显着缺乏吸引力，整洁和安全。此外，水位的这些影响被其他设计元素所缓和。高水位的看法是更积极的池塘在绿地比在住宅或商业环境。低水位的看法是更积极的池塘在住宅环境比绿地或商业环境，以及池塘周围的木本或未经维护的植物比那些周围的草坪边缘。在高和低的水条件下，池塘与陡峭的斜坡被认为是更积极的比那些浅的斜坡。这些研究结果可以支持成功的规划，设计和管理智能NBS。
Smart technologies promise innovative approaches to manage nature-based solutions (NBS) for more effective regulating functions under climate change. However, smart systems may also affect people’s experiences of NBS by introducing noticeable changes in urban landscapes. This study investigated public perception of “smart” retention ponds that had changing water level as controlled by smart systems and varied in the following microscale landscape elements determined by planning and design choices: land use context, basin slope, and surrounding plants. Using visualizations that showed pond landscape design alternatives at typical, low (draining water), and high (retaining water) water levels, we surveyed residents in three American cities for their perceptions of smart ponds (n = 974). Our results suggest that water level manipulation by smart systems negatively affects perceptions of stormwater ponds; both low and high water were perceived as significantly less attractive, neat, and safe than the typical water level condition. Furthermore, these effects of water level were moderated by other design elements. Perceptions of high water level were more positive for ponds in greenspace than in residential or commercial contexts. Perceptions of low water level were more positive for ponds in residential contexts than in greenspace or commercial contexts, as well as for ponds surrounded by woody or unmaintained plants than those surrounded by mown turf edge. In both high and low water conditions, ponds with steep slopes were perceived more positively than those with shallow slopes. These findings can support successful planning, design, and management of smart NBS.
