该文对海南省文昌市不同植被类型不同昆虫种类进行调查。共采得昆虫标本441头,经鉴定隶属于7目24科30属30种,其中以鳞翅目种类最多。结果表明,6个样地的物种丰富度顺次为:混交林样地>椰子林样地>次生林样地>半红树林样地>湿加松样地>木麻黄样地;6个样地的Shannon-Wiener指数为:混交林样地>椰子林样地>次生林样地>半红树林样地>湿加松样地>木麻黄样地;6个样地的均匀度指数变化顺次为木麻黄样地>湿加松样地>半红树林样地>次生林样地>椰子林样地>混交林样地。

This paper studied the different kinds of insects in different ecological types in northeast Hainan.The results showed that there were441specimens and30species of30species were identified by7.The largest number of them were Lepidoptera insects.The species richness of the six samples is as follows:Mixed sample>Coconut forest sample>Secondary sample>HaE mangrove>Wet with little pine sample>Casuarina sample.The Shannon Wiener index of six samples is as follows:Mixed sample>Coconut forest sample>Secondary sample>Half mangrove>Wet with little pine sample>Casuarina sample.The evenness index of six sample change in order for casuarina sample>add wet pine sample area>half mangrove sample sample sample>forest land>coconut forest land>mixed forest sample plots.
