广东韶关市郊不同生境蝶类种群结构及多样性的初步研究

Community structure and diversity of butterflies in different habitats in the suburbs of Shaoguan City, Guangdong Province

20 0 0年 4月～ 2 0 0 1年 1 0月间 ,分别在韶关市郊的西联校园区、芙蓉山公益生态林、沙湖公园、森林公园、沐溪水库区 5个点进行蝴蝶群落结构及多样性的抽样调查研究 ,共收集蝴蝶 1 388只 ,隶属于1 0科 ,35属 ,5 6种。个体数量以凤蝶科最多 ,蛱蝶科次之。种类以蛱蝶科最多 ,凤蝶科次之 ,珍蝶科最少。各样地的多样性指数和物种丰富度排序为 :沙湖公园 >校园绿化生活区 >森林公园 >沐溪水库公益生态林 >芙蓉山公益生态林。

The community structure and diversity of butterflies in five habitats: Xilian Campus, the public welfare ecological forest on the Furong Mountains, Shahu Park, the Forest Park and the ecological forest of the Muxi Reservior, was surveyed from 2000 to 2001. Of the total collection of 1 388 specimens, 55 species of 35 genera in 10 families were identified. Five families predominated: the Pieridae (genera: Pieris Schrank, Eurema Hübner, etc.), Papilionidae (genera: Papilio L., Ggraphium Scopoli, etc), Nymphalidae (genera: Athyma Westwood, Junonia Hübner: etc.), Satyridae (genera: Mycalesis Hübner, Satyrus Latreille, etc). Among genera, Nymphalis Kluk had the most species. The Papilionidae was the most abundant in terms of number of individuals with Nymphalidae next. The Acraeidae were the least abundant in terms of number of genera, species or individuals. Species richness decreased in the following sequence: Shahu Park, Xilian Campus, the Forest Park, the ecological forest in the Muxi Reservior and the ecological forest on the Furong Mountains.
