中文摘要： 2009—2010年对宁波四明山地区的蜻蜓资源进行了野外调查，共采集蜻蜓标本460只，隶属9科32属43种。蜻科Libellulidele为优势科（17种，占总数的39.5％），灰蜻属Orthetrum为优势属（5种，占属总数的15.6％）。单种单属有25个，占总属数的78.1%，说明四明山区蜻蜓区系在起源和构成上比较复杂。四明山区蜻蜓区系以东洋区和跨古北区东洋区种类占优势。调查发现水体污染、湿地过度开发利用已经成为该地区蜻蜓目昆虫及其它水生生物面临的主要威胁。
英文摘要： Field surveys were conducted on the Odonata in the Siming Mountains of the Ningbo Region from 2009 to 2010. 460 Odonata specimens were collected, and a total of 43 species in 32 genera and 9 families identified. The Libellulidae were the dominant family (17 species, 39.5%) of which Orthetrum was the dominant genera (5 species, 15.6%). 25 genera (78.1%) were represented by single species. Oriental and OrientalPalearctic Realm species were the most common. Water pollution and overutilization of marshes are the main threats to the Odonata and other local aquatic organisms.
