Green stormwater infrastructure such as bioretention cells (BRCs) have the potential to influence human well-being through ecosystem services. Many services are regulated by vegetation, but only a handful (primarily regulating services) have been linked to specific plant functional traits that control their provisioning. Less attention has been paid to cultural services (e.g., aesthetics and sense of place, defined as people's attachment to and identification with natural elements that capture the unique character/identity of a place), such that we presently know little about the role plant traits play in regulating cultural services provisioning by BRCs. We address this knowledge gap by 1) quantifying aesthetic services and sense of place for 15 plants that are native to Southern California, U.S., and common in BRCs (human subjects surveys) and 2) the role of plant functional traits in regulating the provisioning of these services (supervised machine learning). Our survey demographic was civil and environmental engineering students in Southern California, who have grown up during a time of increased BRC implementation and are likely to play a role in their future design. Our study suggests that aesthetic services and sense of place in Southern California are regulated by different plant traits (leaf color for aesthetic services and maximum plant height for sense of place) and participant characteristics, particularly psychosocial characteristics like environmental worldviews (defined as an individual's perception of their environmental role in the world), which significantly influenced aesthetic services, but not sense of place. Reflecting these differences, only 4 of the 15 plant species evaluated were found to provide both cultural services well. This suggests that careful attention to plant selection is needed if we want BRCs to co-provide these services, enriching people's experiences with green stormwater infrastructure.

生物保留单元（BRC）等绿色雨水基础设施具有通过生态系统服务影响人类福祉的潜力。许多服务受植被调节，但只有少数（主要是调节服务）与控制其供应的特定植物功能性状相关。对文化服务的关注较少（例如，美学和场所感，定义为人们对自然元​​素的依附和认同，这些自然元素捕获了地方的独特特征/特性），因此我们目前对植物性状的作用了解甚少发挥作用，规范BRC提供的文化服务。我们通过以下方法来解决这一知识鸿沟：1）量化美国南部加利福尼亚州本地的15种植物的美学服务和位置感，在BRC（人类受试者调查）中很常见，并且2）植物功能性状在调节这些服务的提供中的作用（监督式机器学习）。我们的调查对象是南加州的土木和环境工程专业的学生，​​他们在BRC实施不断增加的时代成长，并且很可能在他们的未来设计中发挥作用。我们的研究表明，南加州的审美服务和位置感受不同的植物性状（叶子颜色代表美学服务，最大植物高度代表位置感）和参与者特征，尤其是心理社会特征（例如环境世界观）（定义为个人的感知）对其在世界范围内的环境角色的影响），从而极大地影响了审美服务，但对位置感却没有影响。反映了这些差异，在评估的15种植物中只有4种能很好地提供两种文化服务。这表明，如果我们希望BRC共同提供这些服务，从而丰富人们在绿色雨水基础设施方面的经验，则需要对植物的选择给予认真的关注。
