广东乳源南水湖国家湿地公园蝶类群落多样性及其时序动态研究

Diversity and Temporal Dynamics of Butterfly Community in Ruyuan Nanshuihu National Wetland Park of Guangdong

对乳源南水湖国家湿地公园蝶类资源开展为期3年的监测,设置7条监测样线,总长15.8 km,探究蝶类群落多样性及其时序动态变化。结果表明,在调查到的11科79属139种蝶类中优势种有7种;东洋界物种占优势,有105种,广布种32种,古北界物种仅1种;多样性指数为3.864,均匀度指数为0.783。在季节时序变化上,物种数、个体数、多样性、丰富度、优势度指数皆为秋季>夏季>春季,均匀度方面为秋季>春季>夏季。珍稀濒危保护蝶类有金裳凤蝶、燕凤蝶、珀翠蛱蝶、宽尾凤蝶和箭环蝶。

The butterfly resources in Ruyuan Nanshuihu National Wetland Park were monitored for three years.Seven monitoring lines with a total length of 15.8 km were set up to explore the diversity and temporal dynamic changes of butterfly community.The results indicated that 139 species of butterfly in 79 genera and 11 families were investigated,including 7 dominant species.In terms of fauna,there were 105 species belonged to the Oriental region,32 species belonged to the widespread,and only 1 species belonged to the palaearctic region.The diversity index was 3.864 and the evenness index was 0.783.In terms of seasonal changes,the number of species,individual amount,diversity,richness and dominance index showed autumn>summer>spring,and in terms of evenness,it showed autumn>spring>summer.The rare and endangered butterflies include Troides aeacus,Lamproptera curius,Euthalia pratti,Agehana elwesi and Stichophthalma howqua.
