In recent times demand for enjoying nature and concerns about prospects and impacts of tourism have dramatically increased. Forests and green spaces have been shrinking which has lead to the degradation of tourism resources and devastation from tourist attractions. Negative impact of tourism on the residential environment has also been an issue of major concern.The concept of land use management needs to be employed for developing and managing tourist resorts. The application of the concept is essential for study and analysis of : the situation of land use in the region, changes in land use and impacts/consequences of the land use changes.The followings are the results of this study :1) The digital land use maps of years 1992 and 2002 were made from topographic maps. Overlay analysis was applied on the digital maps which clarified location and size of land use changes from forest to residential and agricultural areas. The analysis also identified the particular places where the land use had been significantly changed to residential areas.2) A significant correlation was found between the area size of residents and buildings in 1992 and population in 1990. Land use change had strong correlation with the capacity for the number of tourists in the region. In addition, it became clear that the effect of tourism spots was small to the land use change.JEL classification : R11, R14
