中文摘要：

采用巴氏罐诱法,对庞泉沟国家级自然保护区的不同功能区——核心区（绿色长廊）、缓冲区（八道沟）、远离农田的实验区（神尾沟）及靠近农田的实验区（八水沟）林地地表隐翅虫亚科级甲虫物种多样性进行调查研究,旨在探明该保护区有代表性林地隐翅虫的物种组成及受不同程度人为干扰下的隐翅虫多样性格局。结果表明：1）共捕获隐翅虫标本1862号,分属于9亚科。其中,前角隐翅虫亚科为优势类群,与四眼隐翅虫亚科、异形隐翅虫亚科、隐翅虫亚科和尖腹隐翅虫亚科一起构成研究样地的常见类群。2）不同功能区生境中隐翅虫物种组成和数量分布各不相同,个体数量核心区最多,其他α多样性各项指标均为缓冲区最高,βw为靠近农田实验区最高。3）群落相似性分析表明核心区与其他3个生境差异性较大,缓冲区与其他3个生境有一定程度上的相似。适度干扰可提高物种多样性,降低人为过度干扰有利于增加隐翅虫生物多样性。

英文摘要：

The effects of biological conservation practice on diversity of rove beetles（Coleoptera：Staphylinidae） were studied in Pangquangou Nature Reserve（111°22＇—111°33＇E,37°45＇—37°55＇N,elevation 1 600-2 831 m）,Shanxi Province,China.Pitfall catches were set in four sites,i.e.,Lüsechanglang of the core zone（CZ）,Badaogou of the buffer zone（BZ）,Shenweigou of the test zone,which is far from farmlands（TZFF） and Bashuigou of the test zone,which is near to farmlands（TZNF） to catch the beetles from May to September in 2006 and 2007.A total of 1 862 rove beetles belonging to 9 subfamilies were caught.Of these rove beetles caught,Aleocharinae accounted for 80.15% in number,as the dominant group;Staphylininae,Oxytelinae,Omaliinae and Tachyporinae accounted for from 1%~10%,as the common groups;and the Proteininae,Pseudopsinae,Steninae and Xantholininae accounted for less than 1%,as the rare groups.The Proteininae,Pseudopsinae and Xantholininae are the newly recorded subfamilies in Shanxi.There were difference in the beetle composition and numbers among the sites.CZ had the greatest number of individuals and relatively lower evenness index.BZ had a very high richness,diversity and dominance index.TZNF had a very high β-diversity index.A branching pattern was established for groups linkage,based on sub-family assemblages of the rove beetle in the four sites with Euclidean distance.BZ and TZFF were similar;CZ had a very low similarity with other zones.It is inferred that the high diversity of rove beetles species in BZ may be due to the edge-associated species and the presence of species from the adjacent habitats.Nevertheless,the biological conservation practice,which could relieve the pressure of human disturbance,significantly contributed to the re-establishment and maintenance of the diversity of rove beetles assemblages in the studied area.
