【摘要】 为了解双拥公园不同生境访花昆虫资源及其多样性，调查了不同生境类型中的访花昆虫资源与分布情况。结果表明，本研究共采集与观察到访花昆虫1 548只，隶属于6目42科89种，野生与栽培植物共记录1 308株，隶属于17科40种。不同生境传粉昆虫多样性指数（H’）由高到低为灌木生境>路边花草生境>草甸生境>乔木生境；均匀度指数（J）由高到低为灌木生境>路边花草生境>草甸生境>乔木生境；优势度指数（D）由高到低为灌木生境>路边花草生境>草甸生境>乔木生境。不同花色及花形对访花者的吸引存在较大差别。本研究为分析访花昆虫对不同植物环境选择的内在因素及其特征研究提供了基础数据，为区域自然生态保护和管理提供了依据。更多还原

【Abstract】 To understand the resources and diversity of flower-visiting insects in the different habitats of the Shuangyong Park, the resources and distribution of flower-visiting insects in different habitat types were investigated.The results indicated that a total of 1 548 flower-visiting insects were collected and observed, belonging to 6 orders,42 families, and 89 species, with a total of 1 308 wild and cultivated plants recorded, belonging to 17 families and 40 species. The diversity index(H’) of pollinator insects in different habitats, from high to low was shrub habitat >roadside flower habitat > meadow habitat > tree habitat; the evenness index(J), from high to low was shrub habitat >roadside flower habitat > meadow habitat > tree habitat; and the richness index(D), from high to low was shrub habitat >roadside flower habitat > meadow habitat > tree habitat. The study found that there were significant differences in the attraction of flower visitors by different flower colors and shapes. This research provided basic data for analyzing the intrinsic factors and patterns of flower-visiting insects’ habitat selection in different plant environments, and offers a basis for the protection and management of regional natural ecosystems.更多还原
