住宅院子和花园的植物多样性高得惊人。然而，我们仍然不了解驱动单个花园多样性的所有因素，或者花园如何扩大规模以创造更大的城市生物多样性模式。例如，邻居之间的社会互动可能会影响他们是否模仿彼此的庭院设计，从而影响植物群落的空间周转。此外，社区之间的社会经济差异可能导致城市中不同的植物组合。在本文中，我们使用田野调查、GIS和空间统计来研究美国伊利诺伊州芝加哥市870个院子前院植被（包括人工和自然植物）的变异性。我们的目标是了解居民社区植物群落的多样性和空间格局，以及它们如何随规模而变化，考虑α、β和γ多样性。我们解决了以下问题：(1)不同社会经济特征的社区中，人工栽培和自然植物的α、β和γ多样性是如何变化的？(2)在小区内部，前院植物群落是否存在空间自相关？如果是这样，那么这些空间格局是否会影响邻域尺度上的植物多样性？我们在芝加哥发现了不同的植物群落和独特的空间模式。自发植物和栽培植物的丰富度和组成在不同的社区之间存在差异，其中一些差异可以由教育等社会经济因素解释。自发植物和人工栽培植物表现出显著的空间自相关，但这种空间自相关一般不影响邻域尺度多样性。对这些空间格局及其社会经济驱动因素的了解可以用于在整个城市中增加对环境友好的庭院管理实践的采用。
Residential yards and gardens can have surprisingly high plant diversity. However, we still do not understand all the factors that drive diversity in individual gardens, or how gardens scale up to create larger patterns of urban biodiversity. For example, social interactions between neighbors could affect whether they mimic each other’s yard design, affecting spatial turnover in plant communities. Further, socio-economic differences between neighborhoods might result in distinct plant assemblages across a city. In this paper, we used fieldwork, GIS, and spatial statistics to examine the variability in front yard vegetation—both cultivated and spontaneous plants—in 870 yards in Chicago, Illinois (USA). Our goals were to understand diversity and spatial patterning of plant communities in residential neighborhoods and how they vary with scale, considering alpha, beta, and gamma diversity. We addressed the following questions: (1) How do alpha, beta, and gamma diversity of cultivated and spontaneous plants vary between neighborhoods with different socioeconomic characteristics? (2) Within neighborhoods, do we see spatial autocorrelation in front-yard plant communities? If so, do those spatial patterns affect plant diversity at the neighborhood scale? We found diverse plant communities and distinct spatial patterns across Chicago. Richness and composition of both spontaneous and cultivated plants differed between neighborhoods, with some differences explained by socioeconomic factors such as education. Spontaneous and cultivated plants showed significant spatial autocorrelation, although that spatial autocorrelation generally did not influence neighborhood-scale diversity. Knowledge of these spatial patterns and their socioeconomic drivers could be exploited to increase adoption of environmentally-friendly yard management practices across a city.
