【Abstract】 This paper dealt with the diversity of butterflies collected from Lianhua Mountain Nature Reserve of Dongguan in April,June,September and December 2001.In this area,there were 50 species butterflies belonging to 9 families,36 genera.Data analysis showed that the species richness and the highest diversity index were the highest in June,followed by in September,April and December,and the evenness index was the highest in April,then in September,June and December.The dominance index was the highest in December,then in September,June and April.At the level of families,Nymphalidae was the highest in richness,diversity [H′(GS)、H′(G)] and evenness,the second was Papilionidae,and then was Hesperiidae.As for individual quantity,Danaidae was the most abundant,and the following were Pieridae and Papilionidea.For diversity index[H′G(S)],Papiliondae was the highest,and the next was Nymphalidae .更多还原
