中文摘要：

2010-2013年,对宁夏灵武白芨滩国家级自然保护区的蜻蜓目昆虫多样性进行了调查研究。结果共获得蜻蜓标本305号,隶属2亚目3科9属13种,其中差翅亚目2科6属9种,束翅亚目1科3属4种。蜻科（5属7种）、蟌科（3属4种）为优势科,长叶异痣蟌、秋赤蜻和黄蜻为优势种。总属种比值系数为0.692,单种属占总属数的66.67%。其区系组成的特点是在世界地理分布中偏向古北区,古北区种占总种数的46.15%,广布种占总种数的30.77%。在中国动物地理区划中共有8类区系型,其中七区型所占比例最高（占38.46%）;四区型和五区型次之;六区型分布仅有1种,无单区型、双区型和三区型分布的种,表明宁夏灵武白芨滩国家级保护区蜻蜓目昆虫在中国动物地理区划中区系关系和构成较为复杂。

英文摘要：

From 2010 to 2013,the Odonata diversity were surveyed in Ningxia Lingwu Baijitan National Nature Reserve. A total of 305 specimens were collected. 13 species of 9 genera in 3 families were identified. 9 species of 6 genera in 2 families were belonged to Anisoptera and 4 species of 3 genera in one family were belonged to Zygoptera. Coenagrionidae（ 3 genera and 4 species） and Libellulidae（ 5genera and 7 species） were dominant families. Ischnura elegans,Sympetrum frequens and Pantala flavescens were dominant species. The ratio of total genera and species was 0. 692,monotypic genus accounted for 66. 67% of total genera. Most species markedly presented the characters of Palaearctic Region in world geographical distribution. Palaearctic Region species accounted for 46. 15% of total species and Polytopic species accounted for 30. 77%. In the zoogeographic of China,the fauna can be divided into 8 distribution patterns. The seven type distribution was predominant type（ accounted for38. 46%）,followed by the four type distribution and five type distribution. The six type distribution had only one. The single type distribution,two type distribution and three type distribution were absent. It was showed that the relationship and composition of fauna of Odonata were more complicated in Ningxia Lingwu Baijitan National Nature Reserve.
