In order to suggest the integrated management plan for uninhabited islands, the geology and geography of the Docho Islands were studied. The uninhabited islands are composed mainly of the late Cretaceous volcanics, sedimentary rocks and Bulguksa intrusives. Topography around these islands shows typical characteristics of ria coast formed by sea level changes during glacial and interglacial transitions. Islets of Docho Islands were encountered differential wave erosions dependent on direction, showing strong erosion in eastern islets but weak erosion in western ones. In western islets facing open sea, the features of erosion coast such as sea cliffs, wave cut terraces and sea caves related with strong waves were well developed, while the development of beaches and intertidal flat resulted from coastal deposition was very weak. For preservation of natural landscape from wastes and livestock grazing, an appropriate management of uninhabited islands is necessary.
