摘要
水生昆虫（Ａｑｕａｔｉｃｉｎｓｅｃｔｓ）是自然环境的重要成员，参与构成生物多样性（Ｂｉｏｌｏｇｉｃａｌｄｉｖｅｒｓｉｔｙ）。经对昆明市郊山林水环境设８个样点调查，共获水生昆虫５目１５科３０种。其中半翅目（Ｈｅｍｉｐｔｅｒａ）和鞘翅目（Ｃｏｌｅｏｐｔｅｒａ）为两大优势类群。样点Ｓ一Ｖ和Ｓ一Ⅵ水生昆虫种类较多，物种丰富度（Ｓｐｅｃｉｅｓａｂｕｎｄａｎｅｃ）依次为２１和１９；样点Ｓ一Ⅶ和Ｓ一Ⅵ的半翅类昆虫多样性指数即Ｓｈａｎｎｏｎ一Ｗｉｅｎｅｒ指数较大，分别是１．５３００和１．５１２２。
Aquatic insects is a important member in the natural environment and participatein forming biological diversity.Through investigating mountain forest water environment ofKunming suburbs about 8 sites,obtained 30 spieces of aquatic insects, which belong to 5 fam-ilies and l5 orders respectively.Among them,Hemiptera and Coleoptera are two dominantgroups.The kinds of aquatic insects in sites S一Ⅴ and S一Ⅵis more,species abundance are 21and 19 in turn;the biological diversity index,namely Shannon一Wiener index of Hemiptera iasites S一Ⅶand S一Ⅵare quite big,which are 1.5300 and 1.5122 respectively.
