东莞莲花山自然保护区蝴蝶群落多样性研究

记述了东莞莲花山自然保护区的蝴蝶9科36属50种；分析了不同季节蝴蝶群落的特点和在科、属、种级分类下的多样性指数[H′(GS)、H′(G)、H′G(S)]．结果表明，物种丰富度以6月份最高为34，9、4、12月则分别为18、14、2；多样性指数也是以6月份最高为2．9041，9、4、12月则分别为2．5547、2．4842、0.1085；均匀度指数以4月份最高为0.9413，9、6、12月则分别为0.8827、0.8235、0.1565：优势种以12月份最明显，报喜斑粉蝶的优势度指数高达0.9773，其次，9月份为宽边黄凤蝶(0.2571)、6月份为巴黎凤蝶(0.2263)、4月亦为巴黎凤蝶(0.2174)；各科蝴蝶物种丰富度、科、属的多样性指数和均匀度指数均以蛱蝶科为最高，分别为12、2．3992、1．9231、0.9655，凤蝶科、弄蝶科次之，个体数量以斑蝶科最大，粉蝶科、凤蝶科次之，而属内种的多样性指数则以凤蝶科最高(1．5456)，蛱蝶科次之(0.4761)。

Diversity of butterflies in Lianhua Mountain Nature Reserve of Dongguan City, Guangdong Province

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.
