内蒙古东部地区长蝽总科的分布及多样性分析

选取内蒙古呼伦贝尔市、兴安盟、通辽市、赤峰市4个样地,采用野外调查、形态分类学和生物多样性研究方法,分析内蒙古东部地区长蝽总科分布情况。明确该地区长蝽分属7科48种,以地长蝽科Rhyparochromidae物种最丰富(20种),长蝽科Lygaeidae次之(12种)分布情况。在4个样地中,呼伦贝尔市物种最丰富(34种),通辽市最少(13种),Shannon-Wiener多样性指数、Pielou均匀度指数和Simpson优势度指数由大到小依次为呼伦贝尔市、兴安盟、赤峰市、通辽市。相似性分析表明赤峰市与呼伦贝市、赤峰市与兴安盟长蝽群落中等相似;通辽市与其他三地相似性均较低。长蝽分布与多样性情况可能与生境、食物、寄主和自身适应性等因素相关。

Distribution and diversity analysis of Lygaeoidea in the eastern Inner Mongolia

Using field investigation,morphological taxonomy and biodiversity methods,selecting the Hulunbuir City,Xingan League,Tongliao City and Chifeng City of Inner Mongolia as four samples,Lygaeoidea species of the eastem Inner Mongolia were analyzed.The results showed that seven families 48 species were distributed in eastem Inner Mongolia.The most abundant family was Rhyparochromidae (20 species),and the second one was Lygaeidae (12 species).Among of the four samples,Hulunbuir City had the most species (34 species) and Tongliao City had the fewest species (13 species).Shannon-Wiener diversity index,Pielou evenness index and Simpson dominance index from large to small were Hulunbuir City,Xingan League,Chifeng City and Tongliao City.Similarity analysis showed that Lygaeoidea communities of Chifeng City with Xingan League and Chifeng City with Hulunbuir City were medium similar;,and Tongliao City with other three cities were low similarity.The distribution and diversity of Lygaeoidea in eastem Inner Mongolia might be related to habitats,foods,hosts and its adaptabilities etc.
