城市扩张与生物多样性负向趋势相关。城市地区不透水表面的数量是传粉者物种组合的决定因素。虽然城市化和不透水地表的增加对传粉媒介产生了负面影响，但城市也包含城市绿地，这些绿地具有支持生物多样性的重要能力。其中，代表绿色空间不可忽视的一部分的家庭花园已被证明有利于传粉媒介。家庭花园可能在居民区形成生境集群，但其景观价值尚不清楚。本文研究了不透水地表和园林面积对传粉媒介丰富度的综合影响。由于很难进入私人拥有的家庭花园，我们选择使用来自一个成熟的法国公民科学项目SPIPOLL的公民科学数据。通过对数据点周围50米至1000米缓冲区的回归树分析，我们显示了传粉者在靠近家庭花园的地方的重要性，作为嵌入在景观中的当地有利栖息地，在景观中，不透水的表面代表不利区域。我们强调了当地和景观尺度之间的相互联系，住宅小区家庭花园的潜力，以及考虑园丁在景观背景下协调管理决策的潜力的必要性。(C) 2018 Elsevier B.V.版权所有
Urban expansion is correlated to negative biodiversity trends. The amount of impervious surfaces in urban areas is a determinant of pollinator species assemblages. While the increase in urbanization and impervious surfaces negatively impacts pollinators, cities also encompass urban green spaces, which have a significant capacity to support biodiversity. Among them, domestic gardens that represent a non-negligible fraction of green spaces have been shown to benefit pollinators. Domestic gardens may form habitat clusters in residential areas, although their value at a landscape scale is still unknown. Here, we investigate the combined effects of impervious surfaces and domestic garden areas on pollinator richness. Due to the difficulty of accessing privately owned domestic gardens, we chose to use citizen science data from a well-established French citizen science program known as SPIPOLL. Using regression tree analysis on buffers located from 50m to 1000m around the data points, we show the importance of pollinators being in close proximity to domestic gardens as locally favorable habitats that are embedded within a landscape, in which impervious surfaces represent unfavorable areas. We highlight the inter-connection between local and landscape scales, the potential for patches of domestic gardens in residential areas, and the need to consider the potential of gardeners' coordinated management decisions within a landscape context.
