Abstract:

The resources of dragonflies are investigated in some habitats which were suitable to dragonflies in Maolan area of Guizhou in July, 2011. The dragonflies were recorded and collected in the space of 20 metres along the sample lines by watching and netting methods, the fauna and diversity of the dragonflies were also analysed after the identification and calculation. The results showed: 1) 65 species were recorded in Maolan area of Guizhou which belonged to 42 genera, 11 families. 2) Oriental species was a dominant one which owned 31 species accounted for 47.69% in total; Palearctic species was relatively poor, accounting for 1.54% in total. 3) The diversity index in Maolan area of Guizhou dragonfly was 2.8617, the evenness index was 0.6855, and the dominance index was 0.1385, and the superiority centrality index was 0.1006. 4) the similarity index of these five sample sites were between 30% to 55%, only two of them were over 50%, which was 53.41% in Laocun-Wengang, and 52.77% in Laocun-Banwang, it was possibly related to the habitats in Maolan area which were more suitable for the dragonfly and higher in the diversity of habitats.
