【摘要】 海南南湾自然保护区共记录等翅目昆虫—白蚁３科５属１０种，其中天涯锯白蚁、海南土白蚁为优势种。南湾白蚁的Ｓｉｍｐｓｏｎ指数λ＝０．４１４，ＰＩＥ指数ＰＩＥ＝０．５８６，Ｓｈａｎｏｎ－Ｗｉｅｎｅｒ指数Ｈ１＝１．２９０，Ｐｉｅｌｏｕ指数Ｊ１＝０．５６０，Ｗｈｉｔａｋｅｒ指数βＷＳ＝３．１３。南湾白蚁物种组成分为二种类型：第一类型是天涯锯白蚁和细颚士白蚁，这一类型占调查样方的４２．１％；第二类型中有恒春新白蚁、台湾乳白蚁、异头乳白蚁、黄翅大白蚁、黑翅土白蚁、海南土白蚁以及天涯锯白蚁和细颚土白蚁等，这一类型占调查样方的５２．６％；第二类型仅出现在１个样方，有海南大白蚁、平行土白蚁、海南土白蚁、台湾乳白蚁、细颚土白蚁等。天涯锯白蚁、台湾乳白蚁、海南土白蚁和细颚土白蚁是影响白蚁物种组成类型的主要种类更多还原

【Abstract】 Ten species of Isoptera were recorded at Nanwan Nature Reserve, Hainan, China through investing in nineteen samples of 0.25 km 2 area. These species belong to three families, and five genera. Microcerotermes remotus Ping et Xu and Odontotermes hainanensis(Light) of the termite at Nanwan were superiority species. The hiodiersity indices of termite at Nanwan were calculated depending research results. Simpson index: λ=0.414, PIE index:PIE=0.586, Shanon Wiener index:H 1=1.290, Pielou index:J 1=0.560, Whittaker index:β WS =3.13. The species composition of termite′s community could be distinguished into three types. The first type consisted of M.remotus ping et Xu and O.angustignathus Tsai et Chen. The type occupied eight of nineteen samples. There were eight species in the second type. They are N.koshunensis (Shiraki), C.formosanus Shiraki, C.varicapitatus Tsai et Li, M.barneyi Light, O.formosanus Shiraki, O.hainanensis (Light), and first type termite′s community two species. The sample of this type was 52.6% in total samples. The last one termite′s community only one investing sample obtained five species that were M.hainanensis Li et Ping, O.parallelus Li. O.hainanensis (Light), C.formosanus Shiraki and O.angustignathus Tsai et Chen.更多还原
