综述目的虽然数十万种昆虫、哺乳动物和鸟类依靠花作为食物或繁殖，但令人惊讶的是，专门关注花卉资源的文献匮乏。在城市地区，了解花卉资源的可获得性尤其必要，因为城市地区最近被提议作为传粉者数量下降的重要栖息地。在这项研究中，我们的目的是综合现有的信息，并就土地利用和土地覆盖(LULC)变化和城市化对植物资源的分布、多样性和丰度的影响提供新的见解。特别是，城市土地可能比农业或自然土地具有更高的植物密度。然而，我们也观察到不同研究之间的不同结果，城市化和花卉资源可获得性之间的关系可能因城市而异，这种差异可能部分是由于城市规模、LULC组成、区域生物群以及采样中的偏差。然而，要全面了解城市化对花卉资源的影响，就必须考虑景观组成和异质性。我们建议更多的研究通过结合关于LULC组成的数据和关于不同LULC类型内的花卉资源可用性的数据来估计景观尺度上的植物资源可用性。这些研究应特别侧重于花卉社区，并沿着整个城乡梯度进行。
Purpose of ReviewWhile several hundred thousand species of insects, mammals, and birds rely on flowers for food or reproduction, a surprising dearth of literature focuses specifically on floral resources. An understanding of floral resource availability is particularly necessary in urban areas, which have recently been proposed as important habitat for declining pollinator populations. In this study, we aim to synthesize existing information and provide new insights about the effects of land use and land cover (LULC) change and urbanization on the distribution, diversity, and abundance of floral resources.Recent FindingsOur results suggest that certain LULC types provide more floral resources than others. In particular, urban lands may have higher floral density than agricultural or natural lands. However, we also observed inconsistent findings between studies, and the relationship between urbanization and floral resource availability may vary by city, with this variation possibly due in part to city size, LULC composition, regional biome, and biases in sampling.SummaryIt appears that cities have the potential to provide an important source of floral resources. However, a complete understanding of the effects of urbanization on floral resources requires that landscape composition and heterogeneity be taken into account. We recommend that more studies estimate floral resource availability at a landscape scale by combining data about LULC composition with data about floral resource availability within various LULC types. These studies should focus specifically on flower communities and be conducted along a full urban-rural gradient.
