Plant-soil feedbacks not only shape plant communities but also the abiotic and biotic nature of soils. These feedbacks are well-studied in natural and agricultural landscapes, but poorly studied in cities. Here, we investigated soil fungal communities, vegetation and soil abiotic properties in five urban green space types within urban Adelaide, South Australia. We surveyed eight, spatially-independent replicates of Sport Fields, Community Gardens, Parklands, Young Revegetation, and Old Revegetation sites. Vegetation strongly associated with soil fungal abundance and diversity. Revegetated urban green spaces had appreciably higher fungal diversity than other spaces, as well as greater richness in saprotrophic and pathotrophic fungi. We suggest that restoration of urban green space fungal microbiomes appears possible via replanting the native vegetation community. Such revegetation interventions will likely have positive outcomes for not only biodiversity conservation but also human health, via re-creating a biodiverse environmental microbiome.

植物-土壤的反馈不仅影响植物群落，而且影响土壤的非生物和生物性质。这些反馈在自然和农业景观中得到了很好的研究，但是在城市中却研究得很少。在这里，我们调查了南澳大利亚州阿德莱德市内五种城市绿地类型中的土壤真菌群落，植被和土壤非生物特性。我们调查了运动场，社区花园，公园，年轻植被和旧植被地点的八个与空间无关的副本。植被与土壤真菌的丰度和多样性密切相关。植被绿化的城市绿地比其他空间具有更高的真菌多样性，并且腐生和病原真菌的丰富性更高。我们建议，通过重新种植原生植被群落，似乎有可能恢复城市绿地真菌微生物群。通过重新创建生物多样性的环境微生物组，这种植被干预措施不仅可能对生物多样性保护而且对人类健康都有积极的成果。
