摘　　要：2010年3—10月,沿城市发展梯度选取了合肥市3个区域(城市、城郊和农村),进行蝴蝶调查。共采集蝴蝶1484只,隶属7科28属34种。结果表明:研究区域优势种蝶类为菜粉蝶(Pieris rapae)、酢浆灰蝶(Pseudozizeeria maha)、黄钩蛱蝶(Polygonia c-aureum);合肥不同城市化区域蝶类多样性存在差异,其多样性指数变化趋势为农村>城郊>城市;农村和城郊的多样性指数和丰富度指数在7月最高,城市8月最高;城市和城郊的优势度指数在8月最高,农村7月最高;3种不同城市化区域的均匀度指数均是8月最高。在快速城市化过程中,应根据不同城市化水平、不同生境类型采取不同的措施,保护和促进城市生物多样性。To investigate the butterfly diversity in Hefei,we selected three regions along a gradient of urbanization,namely urban,suburban and rural regions from March to October,2010. A total of 1484 butterfly individuals were collected,belonging to 7 families,28 genera and 34 species,among which Pieris rapae,Pseudozizeeria maha and Polygonia c-aureum were dominant species. Diversity index of butterfly varied with the three different urbanization regions. The diversity indices of butterfly in the three different urbanization regions were in order of rural site suburban site urban site. Temporally,the Shannon index and richness index at rural and suburban sites were the highest in July,while they were the highest in August in urban site. The Simpson index at urban and suburban sites was the highest in August,while it was the highest in July at rural site. The evenness index in the three different urbanization areas was the highest in August.Therefore,it was suggested that different measures should be taken to conserve and enhance the biodiversity based on the urbanization level and habitat type under rapid urbanization.
