摘要
于2005—2008年对江西怀玉山地区的蜻蜒资源进行调查，经过对采集标本的鉴定，初步确定江西怀玉山地区蜻蜒目昆虫有12科、33属、44种，其中16种是江西省新纪录。该地区蜻蜒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；种类个体数量表现为春季〉秋季；该地区蜻蜒的多样性指数为2．7188，优势度指数为0．1136，均匀度指数为0．7185，优势集中性指数为0．1097。
Based on the identification of specimens of odonata collected in Dazhang mountain in Jiangxi Province from the year 2005 to 2008,44 species were classified into 12 families and 33 genus. 16 species among them are recorded in Huaiyu Mountain in Jiangxi Province for the first time. The characteristics of the fauna show that the percentage of oriental species is higher than that of palearctie species, and the percentages of cosmopolitan species is the lowest. The number of individuals appears as spring 〉 autumn. The region＇ s diversity index for the dragonflies is 2.718 8, the index for dominance 0.113 6, the index for niformity of 0.718 5, the index for superiority centrality of 0. 109 7.
