Odonata are widely distributed in the global scale. Their distribution and abundance influenced by various environmental factors where they habit. Therefore, their distribution patterns reflect the differences of their habitat condition. In this study, we characterized the distribution patterns of Odonata in korean streams by considering various environmental condition such as geographical, landscape, hydrological, and water quality factors. Species Ischmura asiatica, Cercion calamorum, and Onychogomphus ringens displayed the highest abundance and occurrence frequency in the dataset. Among various environmental factors altitude was the most contributing factors on the distribution of Odonata species, and the species richness was higher at low land than at high land.
