In the history of civilization, small islands have played a complementary role in the formation and evolution of human civilizations of neighboring lands. Because these islands have always acted as anchorages for stopping and strengthening the seafarers, as well as loading and unloading marine cargoes, and depending on the geopolitical situation, they have acted as advance fortresses in attack and defense. Over time, the function of Kharg Island has accepted many changes in form and substance and has played a role as an island city in the human ecology of the Persian Gulf and the southern coasts of Iran. The function of external environmental forces in accepting the first position of Iran's oil export has many impacts, In the current research, the study of "landscape ecology" is considered. In this research, by using library resources, after representing the history of the island, it is intended to produce thematic maps in GIS software for the spatial description of its environmental features. In the following, by using Google Earth software, the spatial changes of the island and the transformations of the landscape elements (Patch - corridor) were monitored in recent decades. The findings from the above research path indicate the attrition, shrinking and isolation of the island's biological patchs, which has resulted in the decline of ecosystem services, according to the principle of "structure-function". Therefore, with the aim of adjusting the disturbances in the landscape and improving the ecological conditions, proposals have been presented with the approach of "Integrated Coastal Zone Management".
