摘要: Urban gardens are popular green spaces that have the potential to provide essential ecosystem services, support human well-being, and at same time foster biodiversity in cities. We investigated impact of gardening activities on five soil functions relationship between plant (600 spp.) fauna (earthworms: 18 spp., springtails: 39 85 urban (170 sites) across city Zurich (Switzerland). Our results suggest high diversity had a positive effect multifunctionality, garden management intensity decreased diversity. Indices biological activity soil, such as organic microbial carbon bacterial abundance, showed direct multifunctionality. Soil moisture disturbance, driven by watering tilling, were driving forces structuring communities. Plant indicator values proved useful assess community structure, even anthropogenic assemblages. conclude enhance functions, gardeners should increase diversity, lower intensity. protective practices, applying compost, mulch or avoiding be included space planning improve nature’s contribution people.
