The Study Of Butterfly Species Diversity In Mt.Fengyang Of Zhejiang Province

For the sake of exploring the butterfly species diversity with time and space and in Mt.Fengyang of Zhejiang Province,as well as the factors affecting butterfly species diversity,and put forward corresponding protection measures.From April 2017 to September 2019,this study took Mt.Fengyang as the research area,and set up 7 butterfly monitoring sample lines according to different vegetation types,habitat types,altitude gradients,human interference and other factors,namely Dasai Village(?),Fengyu Villa(?),Shatian Village(?),Huangmaojian Peak(?),Fengyang Lake(?),Luao Village(?)and Datianping(?).Using the method of sample line monitoring,7 sample lines were monitored once a month,and 18 monitoring datas were obtained for each sample line in three years.In this study,the species diversity of butterflies in Mt.Fengyang was analyzed from the aspects of species diversity model,diversity index analysis and similarity comparison.The main results were as follows:(1)A total of 6430 butterflies,belonging to 5 families,128 genera and 261 species,were detected in 7 lines of Mt.Fengyang.Among them,there are 22 species in Papilionidae 6 genera,15 species in Pieridae 9 genera,127 species in Nymphalidae 51 genera,44 species in Lycaenidae 31 genera,53 species in Hesperiidae 31 genera.The number of genera,species and individuals of Nymphalidae is significantly higher than other families,which is the dominant group in Mt.Fengyang.On the whole,the species abundance relationship of butterfly community in Mt.Fengyang obeys the normal distribution of Preston logarithm,which indicates that the butterfly community structure in Mt.Fengyang is stable,the ecological environment is good,and the human interference is small.(2)The change trend of species diversity of butterflies in different sample lines:the diversity index is line ?>?>?>?>?>?>?,the dominance index is line?>?>?>?>?>?>?,and the species richness is line ?>?>?>?>??>?>?.The variation trend of butterfly species diversity in different months:diversity index is June>July>September>May>April>August,dominance index is August>April>May>September>July>June,species richness index is July>June>September>September>August>May>April.The diversity trend of butterfly in different altitude gradients:the diversity index is low altitude zone ?>middle and high altitude zone ?>high altitude Zone ?>middle uplift zone ?,the change of dominance index is opposite to the change of diversity index,and the change of richness index is low altitude zone ?>middle and high altitude zone III>middle uplift zone ?>high altitude zone ?.(3)The results show that the similarity coefficients of the two lines are the highest,which are located in the low altitude area and close to each other.The similarity coefficient of butterfly species in August and September is the highest.The similarity analysis of different altitudes shows that the middle and high altitudes are the most similar.Compared with other areas of Zhejiang Province,the similarity coefficient of butterfly species in Mt.Fengyang and Mt.Tianmu is the highest.(4)The relationship of butterfly species change in different years:the number of genera and species of butterfly is 2019>2018>2017,and the change trend of individual number is just the opposite.Diversity trend:diversity index 2019>2017>2018,richness index 2019>2018>2017.
