作为中国的首都，北京有着超过800年的城市化历史，是一个独特的城市生态学研究对象。城市化会对蝴蝶群落产生巨大的影响。然而，目前还没有相关报道对北京城市公园中的蝴蝶物种多样性和分布进行研究。
近期，在发表于Scientific Reports的Ring roads and urban biodiversity: distribution of butterflies in urban parks in Beijing city and correlations with other indicator species一文中，来自中国科学院昆明动物研究所的Kong-Wah Sing及同事首次在北京市十个城市公园中对蝴蝶开展了调查，并评估了它们的物种多样性。此外，作者研究了蝴蝶的物种分布模式，并分析了蝴蝶物种多样性与公园相关变量（建成时间、面积、与城市中心的距离）之间的关系，并调查了其他指示生物类群（鸟类与植物）的物种多样性。
作者收集到了587只蝴蝶，分属于来自5个科的31个物种；其中74%的物种分布广泛。蝴蝶物种多样性和丰度最高的公园位于城市的周边区域。物种多样性和公园与城市中心的距离呈显著的正相关关系(p < 0.05)，而物种多样性与公园的建成时间、面积或其他指示生物之间没有显著的相关关系(p > 0.05)。本研究首次提供了北京城区中蝴蝶物种的相关数据，为后续调查和保护工作提供了基线。
摘要：The capital of China, Beijing, has a history of more than 800 years of urbanization, representing a unique site for studies of urban ecology. Urbanization can severely impact butterfly communities, yet there have been no reports of the species richness and distribution of butterflies in urban parks in Beijing. Here, we conducted the first butterfly survey in ten urban parks in Beijing and estimated butterfly species richness. Subsequently, we examined the distribution pattern of butterfly species and analyzed correlations between butterfly species richness with park variables (age, area and distance to city center), and richness of other bioindicator groups (birds and plants). We collected 587 individual butterflies belonging to 31 species from five families; 74% of the species were considered cosmopolitan. The highest butterfly species richness and abundance was recorded at parks located at the edge of city and species richness was significantly positively correlated with distance from city center (p < 0.05). No significant correlations were detected between the species richness and park age, park area and other bioindicator groups (p > 0.05). Our study provides the first data of butterfly species in urban Beijing, and serves as a baseline for further surveys and conservation efforts.
