摘　　要：2005-2008年对江西大障山地区的蜻蜓资源进行了调查,经过对采集标本的鉴定,初步确定江西大障山地区蜻蜓目昆虫有12科,41属,57种,其中16种是江西省新纪录。该地区蜻蜓目区系组成的特点是：东洋种所占的比例较大,古北种次之,广布种最少。春、秋两季蜻蜓多样性研究表明,春季蜻蜓种数大于秋季,春季（3.2751）的多样性指数大于秋季（2.9029）。Based on the identification of specimens of Odonata collected in DaZhang mountain of Jiangxi from 2005 to 2008,57 species were classified in 12 families and 41 genus. Of which, 16 species recorded in DaZhang mountain are the new distribution record in Jiangxi Province. The characteristics of the fauna show that the percentage of Oriental species is higher than that of Palearctic species, and the percentages of cosmopolitan species is the lowest. According to a constant research of Odonata in different seasons, the species diversity decreased in seasons of autumn, spring, the numbers of Odonata in spring were more than in autumn, the species diversity in spring （3. 2751 ） were more than in autumn （2. 9029）.
