Data underlying the publication: Scarcity of flowering plants on Sedum roofs limits pollinator diversity

This study investigates how green roof characteristics and surrounding landscapes influence pollinator diversity and abundance in urban areas. Researchers collected ecological data on pollinators (bees, wasps, hoverflies, and butterflies) using pan traps and hand netting across 25 green roofs categorized as sedum roofs, nature roofs, and roof gardens. The dataset includes measures of species richness, abundance, and functional diversity, alongside roof-level variables (flower diversity, vegetation cover, microrelief, roof size, height, and age) and landscape factors (percentage and proximity of surrounding green space). The research aims to identify which factors most strongly shape pollinator communities, providing evidence-based guidance for designing pollinator-friendly green roofs.

本研究旨在探究城市环境中绿色屋顶（green roof）的特征及其周边景观如何影响传粉昆虫的多样性与丰度。研究人员采用盘式诱捕器（pan traps）与手持网捕的采样方法，在25座分别归类为景天屋顶（sedum roofs）、自然型屋顶与屋顶花园的绿色屋顶上，收集了涵盖蜂类、胡蜂、食蚜蝇与蝶类的传粉昆虫生态学数据。本数据集包含物种丰富度、个体丰度与功能多样性等传粉昆虫群落指标，同时纳入了屋顶层面变量（包括花卉多样性、植被覆盖度、微地形起伏、屋顶面积、高度与使用年限）以及景观因子（周边绿地占比与邻近距离）。本研究旨在明确对传粉昆虫群落塑造作用最为显著的影响因素，以期为设计适配传粉昆虫的绿色屋顶提供循证指导依据。
