Data underlying the master thesis: Factors influencing invertebrate diversity on green rooftops in the Netherlands

This study investigates how green roof characteristics and surrounding landscapes influence pollinator diversity and abundance in urban areas. Researchers collected ecological data on arthropods, using pan traps, pitfalls and hand netting across 21 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 biodiversity-friendly green roofs.

本研究探讨了城市区域内绿色屋顶特征与周边景观如何影响传粉者的多样性及种群丰度。研究人员采用色盘诱捕器、陷阱诱捕器与手持网捕三种采样方法，在21座归类为景天（Sedum）屋顶、自然型屋顶与屋顶花园三类的绿色屋顶上采集节肢动物的生态数据。该数据集包含物种丰富度、种群丰度与功能多样性的相关测度指标，同时涵盖屋顶层面变量（花卉多样性、植被覆盖度、微地形、屋顶面积、高度与使用年限）以及景观因子（周边绿地占比与空间邻近度）。本研究旨在明确对传粉者群落结构影响最为显著的驱动因素，可为设计具备生物多样性友好性的绿色屋顶提供循证指导。
