摘　　要：为探明湿地环境多样性对蜻蜓目昆虫物种多样性的影响,于2020年7月至8月对台州市不同湿地环境中蜻蜓目昆虫物种多样性进行调查。采用扫网法采集蜻蜓目昆虫,分析方法采用Shannon-Wiener多样性指数和相关性指数。结果表明,在所有样地中,以蜻科种类最为丰富,其中黄蜻在植被低矮的湿地环境中个体数量较多,红蜻在池塘分布较多的水库和溪流环境中数量较多,玉带蜻在树木高大、池塘交错的湿地环境中数量较多,异色多纹蜻在水库周边环境较好的地方数量众多。相关性分析表明:蜻蜓目物种多样性与水陆面积比呈负相关关系,随着水域面积的增大,蜻蜓目的物种多样性呈下降趋势;水陆面积比例在9%至12%之间的蜻蜓目物种多样性指数最高。此研究结果为湿地环境保护和水质评价提供了生物多样性数据支持。In order to explore the impact of wetland environmental diversity on the species diversity of Odonata insects,the species diversity of Odonata in different wetland environments of Taizhou was investigated from July to August in 2020.The dragonflies were collected by scanning net method,and the Shannon-Wiener Diversity Index and Correlation Index were used for the analysis.The results showed that the species of Odonatae were the most abundant in all the plots.Among them,the Pantala Flavescens had a large number of individuals in wetland environments with low vegetation,and the Crocothemis Servilia was found in reservoirs and streams with more ponds.There were quantities of Pseudothemis Zonata in the wetland environment with tall trees and intertwined ponds,and there were plenty of Deielia Phaon in places with better environments around the reservoir.Correlation analysis showed that there was a negative correlation between the species diversity of Odonata and the ratio of water area to land area.With the increase of water area,the species diversity of Odonata showed a downward trend.However,as the proportion of land and water area ranging from 9%to 12%,the species diversity index of Odonata was the highest.The results provided biodiversity data support for wetland environmental protection and water quality assessment.
