Abstract:At present, due to the influence of human activities, the butterfly habitat area is gradually decreasing, which poses a direct threat to the survival and reproduction of butterflies. Using urban butterfly population, the influencing factors of butterfly diversity in urban green space were analyzed by sorting out relevant literature and data. Finally, from the perspective of urban small green space, this paper discusses the butterfly micro habitat optimization path, puts forward 'mutual, total, mission' three ecological landscape strategies, combined with the needs of butterfly habitat and human interaction, to build an all-age urban butterfly micro-habitat based on native plants, emphasizing on management and maintenance, and integrating ecological popularization and nature education.
