This paper systematically reviews the common ornamental fruit tree species resources in Northeast China(including later introduced species), then focuses on elaborating their diverse forms of application in landscape gardening. Meanwhile, it proposes key points for maintenance and management that need attention during application, aiming to provide theoretical basis and practical references for the rational selection of ornamental fruit tree species in landscape construction of Northeast China, as well as enhancing landscape quality and ecological value.
