广州市城镇型绿道蝴蝶群落多样性研究

2019年4—11月,采用样线法对广州市城镇型21条绿道的蝴蝶群落结构多样性进行调查,分析了不同月份蝴蝶群落特点。共记录蝴蝶7科27属31种106头,酢浆灰蝶Pseudozizeeria maha和东方菜粉蝶Pieris canidia是优势种。粉蝶科Pieridae物种数最多,灰蝶科Lycaenidae次之;蛱蝶科Nymphalidae属数最多,粉蝶科和灰蝶科次之,蚬蝶科Riodinidae最少。物种丰富度、各科的种属多样性指数以蛱蝶科最高,分别为2.52、1.99和1.99,优势度指数则最低,为0.25。不同月份优势类群和常见类群不同,7月的蝴蝶多样性指数明显高于4月和11月,优势度指数则最低。蝴蝶多样性可为城镇型绿道品质提升提供数据参考。

Diversity of Butterfl ies Community in Urban Greenways of Guangzhou

From April to November in 2019,the diversity of butterfly community structure in 21 line transects of four districts in Guangzhou was investigated by using the line transect method,and the characteristics of butterfly community in different months were analyzed.A total of 106 individuals of 31 butterfly species were observed belonging to 27 genera and 7 families. The dominant species were Pseudozizeeria maha and Pieris canidia.Pieridae had the largest number of species,while Lycaenidae followed.Nymphalidae had the largest number of genera,followed by Pieridae and Lycaenidae,and Riodinidae was the least.Shannon-Wiener diversity of individuals,species richness and genera richness of Nymphalidae were the highest,which were 2.52,1.99 and 1.99 respectively,but Berger-Parker index of Nymphalidae was least (0.25).The dominant groups and common groups were different in different months.The diversity index of butterfly in July was significantly higher than that in April and November,but the dominance index in July was the lowest.Butterfly diversity can provide data reference for improving the quality of urban greenway.
