住宅庭院是城市环境的一个独特组成部分，拥有丰富的栽培植物多样性；然而，人们为什么以及如何用这么多的植物种类来建造院子还不是很清楚。为了研究这种模式，我们研究了美国犹他州盐湖谷居民的偏好、收入和庭院植物多样性之间的关系，这里的大部分城市植被都是有意种植的。我们进行了面对面访谈，分发了书面调查，并在不同收入水平的社区的住宅庭院中对观赏草本开花植物和草坪植物的生物多样性（即属和物种丰富度）进行了调查。我们发现，95%的受访居民重视“院子里有能创造多样性的植物”（“多样性”一词有待解释），47%的受访居民表达了对多样性的情感联系。平均而言，居民对一般植物品种的重视程度高于高植物多样性（即特定类型的品种），但他们也表现出对缺乏生物多样性和其他类型品种的整齐的单一草坪的偏好。居民对一般植物品种的偏好，特别是生物多样性，不一定反映在他们的院子里。在不同花色、花序类型和属的数量上，高收入家庭有更多的开花植物种类，但由于杂草种类的减少，草坪物种多样性较低。总体而言，我们的研究表明，该地区大多数居民更喜欢院子里的植物多样性，而不是生物多样性，收入越高的人越能实现这些偏好。
Residential yards are a unique component of the urban environment and harbor high cultivated plant biodiversity; however, why and how people create yards with so many plant species is not well understood. To investigate this pattern, we studied the relationships between residents’ preferences, income, and yard plant biodiversity in the Salt Lake Valley, Utah, USA where most of the urban vegetation is intentionally cultivated. We conducted in-person interviews, distributed written surveys, and inventoried the biodiversity (i.e., genus and species richness) of ornamental herbaceous flowering plants and lawn plants in residential yards located in neighborhoods across income levels. We found that 95% of surveyed residents valued having ‘plants that create variety in the yard’ (‘variety’ left open to interpretation) and that 47% of interviewed residents expressed an emotional connection to variety. On average, general plant variety was more important to residents than high plant biodiversity (i.e., a specified type of variety), but they also exhibited a preference for neat monoculture lawns lacking in biodiversity and other types of variety. Residents’ preferences for general plant variety, and biodiversity specifically, were not necessarily reflected in their yards. Higher income households had greater flowering plant variety in terms of number of different flower colors, inflorescence types, and genera, but lower lawn species biodiversity due to a reduction in weedy species. Overall, our study shows that most residents in this region prefer plant variety in their yards more than biodiversity specifically, and that people with higher incomes can better achieve these preferences.
