2005～2006年,对广州地区4个不同城市化发展区域(森林区、农田区、城市区、沿海湿地区)的蝶类进行6次调查,共统计到10科46属73种.森林区科、属、物种和个体数目都最多,沿海湿地区各项数量指标都最小,农田区的个体数量大于城市区,但科、属和物种数却与城市区差异不大.多样性分析结果表明,森林区的种类丰度、多样性指数最高,沿海湿地区的种类丰度和多样性指数最低;均匀度大小依次为沿海湿地区﹥农田区﹥森林区﹥城市区;优势度指数大小依次为沿海湿地区﹥城市区﹥农田区﹥森林区.相似性分析结果表明,森林区和农田区具有的相同物种数最多,相似性系数最高;沿海湿地区和森林区、农田区、城市区具有的相同物种数都较少,相似性系数也较低.

To investigate the correlation between urbanization and butterfly diversity, four different habitats, i.e. forest, farmland, city and wetland, in Guangzhou were surveyed between 2005 and 2006. 73 species of butterflies from 46 genera in 10 families were recorded. Margalef species richness and Shannon-Wiener indices were used to analyze the species and community diversity of butterfly in the four urbanized regions. The results showed that both indices were the highest in forest regions and the lowest in wetland regions. While, wetland region showed the highest evenness index, followed by farmland, forest and city regions;also, wetland regions have the highest dominance index, followed by city, farmland and forest regions. The highest similarity, in term of numbers of common species, occurred between forest and farmland;in contrast, wetland regions had the most distinct species composition as compared to other regions.
