摘　　要：本文综述了襀翅目昆虫的历史发展及辽西义县组地层中发现的襀翅目化石种类。襀翅目现生昆虫生境范围狭窄,不同类群反映不同的水生环境,将今论古,已发现的襀翅目化石类群反映了高山、河流、山间溪流以及低地湖泊等古环境的存在。襀翅目化石类群反映的这些古环境与地层学分析的沉积环境,以及地层中其他动植物化石反映的古环境相符。The historical development of Plecoptera insects and the fossil stoneflies from the Early Cretaceous Yixian Formation in the Western Liaoning are reviewed. The extant Plecoptra insects generally have narrow and specific habitat,thus different taxa represents different aquatic environment. Present is the key to the past,the discovered fossil groups of Plecoptera indicates that there existed mountains,rivers,mountain streams and lowland lakes environments in the Early Cretaceous in Western Liaoning,which were consistent with the results from stratigraphic analysis on sedimentary environment and the animal and plant fossils assemblage in the same stratum.
