外文摘要：Urbanization has profound impacts on ecological environments.Green spaces are a vital component of urban ecosystems and play a crucial role in maintaining ecologi-cal balance and enhancing sustainability.This study aimed to investigate the community composition characteristics of butterflies in urban green spaces within the context of rapid urbanization.Simultaneously,it explored the status and dif-ferences in butterfly taxonomic diversity,functional diver-sity,and functional traits among different types of urban green spaces,regions,and urban gradients to provide rel-evant insights for further improving urban green space qual-ity and promoting biodiversity conservation.We conducted a year-long survey of 80 green spaces across different urban regions and ring roads within Hefei City,Anhui Province,with monthly sampling intervals over 187 transects.A total of 4822 butterflies,belonging to 5 families,17 subfamilies,40 genera,and 55 species were identified.The species rich-ness,Shannon,Simpson,functional richness,and Rao's quadratic entropy indices of butterflies in urban park green spaces were all significantly higher than those in residential and street green spaces(P＜0.05).Differences in butterfly diversity and functional traits among different urban regions and ring roads were relatively minor,and small-sized,multi-voltine,and long flying duration butterflies dominated urban green spaces.Overall,these spaces offer more favorable hab-itats for butterflies.However,some residential green spaces and street green spaces demonstrate potential for butterfly conservation.
