Abstract: Dragonfly, due to its wide distribution, in-depth research and easy to sample, is an ideal bioindicator for eco.environment assessment. In recent decades, more and more related researches are using dragonfly to assess ecoenvironment. In this review, the related researches were generalized into five types, i.e., general environmental assessment, environment pollution degree assessment, environmental improvement assessment, climate change assessment, and large-scale environmental assessment, and a brief introduction for each type of the researches was given. The current status and deficiency of the researches in China were discussed, and the broad prospects of using dragonfly as a bioindicator for eco-environment assessment were analyzed through the comparison of the superiority of this bioindicator than the others. It was point out that to build up a thoroughly sourced database of dragonfly diversity in China and to develop specific assessment methods could be the most important things to make progress. Using dragonfly as a bioindicator to assess ecological environment would be low-cost, high-efficient, and environmentally friendly, not only important but also necessary to the needs of China today’s economic development.
