摘要: 近年来,绿化造林工程在北京市大规模展开,涉及林地生境类型多样。林地昆虫群落组成和多样性特征受林分树种组成、立地条件、管护方式的影响。通过对北京市5种人工林样地中蛾类群落结构、多样性和相似性及其时空动态特征的调查,探讨了蛾类多样性变化对生境类型的生态响应。结果表明:共获得标本7046头,隶属于25科269种,以夜蛾科(Noctuidae)为优势类群;聚类分析和群落相似性分析表明,市区样地和郊区样地在蛾类群落特征上存在着一定差异,郊区种群多样性指数和均匀度指数较高,市区种群物种优势度和个体数较高。蛾类群落特征与其生境类型、林分质量关系密切,与郊区相比,市区人工林地,特别是腾退林地,爆发虫害的可能性较大,建议对该区域城市林地病虫害重点防控。

Abstract: A largescale afforestation project has been carried out in Beijing in recent years, involving a variety of woodland habitats. Insect community composition and species diversity are closely related to tree species composition, site condition, and management measures of forest stands. In this study, we investigated the structure, diversity, similarity and the spatiotemporal dynamics of moth communities in five types of forest plantations in Beijing, and analyzed the ecological responses of moth diversity to habitat types. The results showed that 7046 specimens belonging to 269 species of 25 families were sampled, with Noctuidae being the dominant group. Results of cluster analysis and community similarity analysis showed that the moth community characteristics were divergent between the urban and suburban habitats. The diversity and evenness indices of the moth community in suburban habitats were higher than that in urban habitats, while the species dominance and abundance in urban habitats was higher than that in suburban habitats. In conclusion, moth community characteristics were closely related to habitat type and stand quality of urban plantations. The risk of pest outbreaks in urban habitats was higher than that in suburban habitats. Pest control in urban plantations, especially in woodlands of vacated areas, should thus be more concerned.

Key words: diversity, stability, moth, habitat quality.
