摘　　要：2016年12月至2018年11月使用样线法对海南东郊椰林中的蝶类群落多样性及季节变化进行调查,分析海南东郊椰林蝶类多样性及季节变化特点。结果表明:海南东郊椰林蝶类昆虫隶属9科54属,共80种。其中物种丰富度以蛱蝶科最高,达到20种;粉蝶科次之,为13种;环蝶科和珍蝶科最低分别为1种。个体数以粉蝶科最高,达到317头;灰蝶科次之,为199头;环蝶科最少,为38头。种级多样性(H(S))以蛱蝶科最高,为2.67;凤蝶科次之,为2.10;环蝶科和珍蝶科最低,为0。属级多样性指数(H(G))以蛱蝶科最高,为2.36;灰蝶科次之,为1.97;环蝶科和珍蝶科最低,为0。蝶类群落的多样性数随季节变化而变化,蝶类物种丰富度6—8月最高,达到75种;3—5月次之,为72种;12月—翌年2月最低,为36种。等级多样性指数(H(FGS))3—5月最高,达到9.37;6—8月次之,为9.33;12月—翌年2月最低,为7.77。均匀度指数3—5月最高,为2.19;优势度指数12—2月最高,为0.15。蝶类种-多度曲线趋于对数正态分布。To clarify the diversity and seasonal variation of butterfly in the Dongjiao coconut forest.An investigation of butterfly diversity was performed by the sample line method in Hainan Dongjiao coconut forest from December 2016 to November 2018.The results indicated that there were 80 species belonging to 54 genera in 9 families were collected.Among them,species richness was highest for the family Nymphalidae(S=20),followed by Pieridae(S=13),the lowest were for Amathusiidae and Acraeidae(S=1).The number of individuals was highest for Pieridae(n=317),the second was for Lycaenidae(n=199),the lowest was for Amathusiidae(n=38).The diversity of the species was highest for Nymphalidae(H(S)=2.67),followed by Papilionidae(H(S)=2.10),the lowest were for Amathusiidae and Acraeidae(H(S)=0).The diversity of the genus was highest for Nymphalidae(H(G)=2.36),followed by Lycaenidae(H(G)=1.97),the lowest were for Amathusiidae and Acraeidae(H(G)=0).The butterfly diversity indexes changes in the seasons.Species richness was highest from June to Aug.,which species richness values were 75;the second was from Mar.to May,which values were 72;the low-est was from Dec.to Feb.,which values were 36.Diversity index(H(FGS))was highest from Mar.to May,which values were 9.37;the second was from June to Aug.,which values were 9.33;the lowest was from Dec.to Feb.,which values were 7.77.Species evenness was highest from Mar.to May,the values were 2.19.Species dominance was the highest from Dec.to Feb.,the values were 0.15.The butterfly species abundance curves conformed to the lognormal distribution.
