北京地区法医昆虫学研究Ⅰ.嗜尸性甲虫物种多样性及其地区分异

STUDIES ON FORENSIC ENTOMOLOGY IN BEIJING DISTRICT Ⅰ. SARCOSAPROPHAGOUS BEETLES AND THEIR LOCAL SPECIFICITY

本项研究系调查北京地区清河、密云、房山三地点与人尸体有关的鞘翅目昆虫，共采集标本878号，经鉴定隶属于13科26属38种，文中列出名录，其中6种为优势种，7种为三个地点都采到标本的普遍分布种。在种类组成上，各地点有明显的地区性差异：仅在清河发现的甲虫有11种（占总种数的40．0％），仅在密云发现的有2种（占15．4％），仅在房山发现的有11种（占52．4％）；唐山的物种多样性指数（H’）是2．45，清河是1．72，密云是1．60。所以，房山种类组成比较特殊。根据此结果，特别是地区的差异，为判断异地移尸提供了基本数据。

This paper is the result of the forensic entomological studies carried out in the suburbs of Beijing (Qinghe, 40°0' N, 116°3'E; Miyun, 40°3'N, 116°8'E; Fangshan, 39° 6'N, 115°9'E). Totally 878 beetle specimens were collected and identified and they contain 38 species belonging to 13 families and 26 genera. There are 11 species (40. 0% of the local total )only found in Qinghe ； 2 species (15. 4 % )only in Miyun; 11 (52． 4 % )only in Fangshan. The three sites show different values of species diversity: Fangshan H' = 2． 45, Qinghe H' = 1. 72, Miyun H' = 1. 60. This result is potentially applicable to find out the removing of corpse between different sites.
