SPECIES DIVERSITY AND DISTRIBUTION CHARACTERS OF INSECTS IN HANWAN NATURE RESERVE OF HAINAN PROVINCE

本文共记录南湾自然保护区昆虫１６目１２６科４５７种，其中，优势类群为：鳞翅目、鞘翅目、双翅目、直翅目、膜翅目、半翅目，它们分别占总科数的１３．４９％、２１．４３％、１４．３０％、９．５２％、１２．７０％、８．７３％；占种类数的２６．０４％、１８．３８％、１２．４７％、１０．５０％、８．３２％、８．１０％。南湾蝴蝶种类十分丰富，有１００种（亚种），占全部昆虫种类的２１．８８％。南湾昆虫种类及季节分布都有明显的热带、亚热带分布特点。与内伶仃及太行山猕猴自然保护区的半翅目、直翅目和蝶类昆虫比较，南湾这三类昆虫的物种丰富度和物种相似性指数都是与内伶仃的比较接近，而比太行山的高出许多。

Abstract spccics of insects, which belong to 16 orders and 126 families, recorded at Nanwan Nature Reserve, Hainan province. Six orders among these insects were superior in number.

They accounted 21 88% of all specics of total insects recorded. The species and seasonal distribution have tropical and subtropical characters obviously. Among Nanwan, Neilingding, and Taihangshan Nature Reserve, species richness and similarity coefficients of Hemiptera, Orthoptera, and Rhopalocera of Lepidoptera at first two reserves are similar, and great higher than that of last one.
