摘　　要：城市土壤中的真菌,尤其是植物和动物致病真菌,对植被生长和人类健康产生重要影响。然而,目前人们对城市绿地土壤中致病真菌分布和影响因素的研究几乎是空白。选取上海绿地土壤为研究对象,收集了社会经济因素和气候因素,测定了土壤理化性质,探讨了这些因素对城市土壤真菌群落尤其是致病真菌多样性及组成的影响。研究表明,城市土壤真菌群落多样性与人均国内生产总值(GDP)显著负相关(P<0.05),且人口密度和人均绿地面积等社会经济因素对真菌群落组成有显著影响。此外,人口密度是影响土壤致病真菌群落组成,特别是动物致病真菌的主要因素,而年均温(MAT)、年降水(MAP)等气候因子对非致病真菌群落组成影响更为显著。因此,随着人类社会经济活动强度的增加,城市土壤真菌多样性会减少,而动物致病真菌的占比会增加。我们的研究首次揭示了社会经济因素对城市绿地土壤病原真菌多样性和群落组成产生的重要影响,为保障城市绿地土壤质量和人类健康提供了重要的科学依据。Soil fungi in urban green space,including plant and animal pathogens,threaten plant growth as well as human health.These fungi can be found in various soil types,including urban green space.However,there is a lack of knowledge regarding the distribution and influencing factors of pathogenic fungi in soils of urban green space.In this study,we conducted research in Shanghai′s urban green spaces to investigate the diversity and influencing factors of soil pathogenic fungi.We found that the greater diversity of plant pathogenic fungi was primarily distributed in the outside of the middle ring road,while the higher diversity of animal pathogenic fungi was mainly concentrated in the inner ring road.In addition,according to the FUNGuild annotation,plant and animal pathogens accounted for 10.7%and 5.7%of the total fungal species,respectively.Specifically,the Volutella,Monographella,Gibberella,Clonostachys and Curvularia were the dominant plant pathogenic fungi,which account for 66%of the total plant pathogenic fungi.The dominant animal pathogenic fungi include Trichosporon,Metarhizium,Madurella,Metacordyceps,and Beauveria,which account for 99%of the total abundance of animal pathogenic fungi.Additionally,our results revealed a negative correlation between soil fungal community diversity and per capita GDP(P<0.05),and significant effects of social-economic factors such as population density and per capita green space area on the composition of fungal communities.The Mantel test analysis revealed that the community composition of pathogenic and non-pathogenic fungi was significantly influenced by mean annual temperature and population density(P<0.05),and pathogenic fungi exhibited a stronger response to population density compared to non-pathogenic fungi.Those results indicated population density had a greater impact on the composition of the pathogenic fungi community(r=0.43),while non-pathogenic fungi community mainly response to mean annual temperature,mean annual precipitation,and per capita green space area.Moreove
