Community Diversity Of Butterfly In Dongzhaigang Mangrove Forest,Hainan,China

This paper mainly studies on the community diversity of butterfly in Dongzhaigang Mangrove Forest.The main conclusions are as follows:(1)In Dongzhaigang Mangrove Forest,we have collected 208 butterflies which belong to 7 families,30 genera,39 species.(2)The species number of Nymphalidae and Lycaenidae are more than the others.The individual number of Pieridae and Danaidae are more than the others.Euploea tuliola,Eurema Hecabe,Neptis Hylas is the dominant species.Euploea is the dominant genus.(3)The species in Oriental region are accounted for 66.67% of the total butterfly species,and the coexisted species both in Oriental region and Palearctic are accounted for 25.64% of the total.This result is different from the result of Butterfly in Hainan Island because of the difference between mountain ecosystems and coastal ecosystems.(4)The community diversity of butterfly in the forest fixed by mangrove forest and terrestrial forest in Daoxue is more than others,because the vegetation abundance in Daoxue is more than the others,and the human disturbance in Daoxue is less than the others.The community diversity of butterfly in the artificial flower bed of Changningwei and the community diversity of butterfly in the dam of Sanjiang are less than the others.It is because that the vegetation abundance in artificial flower bed and the vegetation abundance in dam are less than the others.So the vegetation abundance and the human disturbance are the main effect factors for the community diversity of butterfly.The number of species and the number of individuals in butterfly in February are more than other Month.This shows that the mangrove butterfly community in east harbor is also affected by climate.
