摘要:

2005年5–10月, 自重庆市沙坪坝区到北碚区沿城市生境梯度选取了5个断面(沙坪公园、南溪口、回头坡、鸡公山和缙云山), 进行蝴蝶取样调查。共采获蝴蝶4,802只, 隶属11科41属65种。统计分析表明, 东方菜粉蝶(Pieris canidia)、菜粉蝶(P. rapae)和酢浆灰蝶(Pseudozizeeria maha)等3种为优势种, 青凤蝶(Graphium sarpedon)、宽边黄粉蝶(Eurema hecabe)、连纹黛眼蝶(Lethe syrcis)、黄钩蛱蝶(Polygonia c-aureum)、点玄灰蝶(Tongeia filicaudis)和直纹稻弄蝶(Parnara guttata)等9种为常见种。多样性指数变化趋势为缙云山>回头坡>鸡公山>南溪口>沙坪公园。沿城市生境梯度, 从人为干扰较大的沙坪公园(城市化水平较高的代表)到人为干扰较小的缙云山(城市化水平较低的代表), 蝴蝶多样性指数基本呈递增趋势, 且植被种类丰富度越高、覆盖率越高、日照量越高的生境, 蝴蝶种类和数量越多, 蝴蝶多样性指数也越高。蝴蝶的多样性特征可以作为城市生境质量和环境变化的指标。

Abstract

To investigate the butterfly diversity in Chongqing Municipality, we selected five sampling sections along a gradient of urbanization from Shaping District to Beibei District, namely Shaping Park, Nanxikou, Huitoupo, Jigong Mountain, and Jinyun Mountain. A total of 4,802 butterfly individuals were collected, belonging to 11 families and 41 genera. Of these, the dominant species are Pieris canidia, P. rapae, and Pseudozizeeria maha, while common species are Graphium sarpedon, Eurema hecabe, Lethe syrcis, Polygonia caureum, Tongeia filicaudis, and Parnara guttata. The diversity indexes ranked in the following order:Jinyun Moun-tain>Huitoupo>Jigong Mountain>Nanxikou>Shaping Park. It is concluded that butterfly diversity, which is the highest in Jinyun Mountain and lowest in Shaping Park, increases with vegetation richness, vegetation coverage, and sunlight. Being significantly impacted by urbanization, butterfly diversity can serve as an effective indicator of urban environmental quality and change.
