中文摘要：

于2008年至2009年对宁夏罗山国家自然保护区膜翅目昆虫的种类组成和地理分布特点进行系统研究。结果表明,罗山膜翅目昆虫已定名标本12科33属50种,其中蚁科、蜜蜂科为优势种类。罗山膜翅目昆虫在世界动物地理区划中的归属中以古北区占优势,达66%,跨区分布的＂古北区＋东洋区＂区系型次之,达20%。罗山膜翅目昆虫在中国动物地理区划中的归属以蒙新区（16%）种类为主体。蒙新区、华北区、东北区膜翅目昆虫关系密切。研究结果对保护区生物多样性保护有促进作用和参考价值。

英文摘要：

The community structure and the fauna composition of Hymenoptera fauna were collected and investigated in Luo Mountain from 2008 to 2009. Results showed that 12 families, 33 genus and 50 species insects were indentified. Formicidae and Apidae were the most significant species. In the zoogeographic regions of the world, the main faunistic category is Palaearctic origin, accounted for 66%. Palaearctic origin and Oriental origin accounted for 20%. In the zoogeographic regions of Chi- na, the Mongolia-Xinjiang Region was predominant types for 16%. The relationship of insects in Mongolia-Xinjang, Northeast and North Region of China was the closest of Hemiptera. The results have stimulative effect and reference value for the conservation of biodiversity.
