• During the past few decades, Thailand has sharply lost her forest area. The forest area has been declined from 53% to 26% of the total land area in 1960-1995. The forest covers have been changed to the other types of land use, such as, farmland, urban area, orchard and etc. This study tried to show the process of deforestation in the Mae Klong Watershed Research Station (Lintin), Thongphaphum District, Kanchanburi Province, Thailand. This case study is valuable to understand drastic land use and land cover changes in rural area in Thailand. Five different time series of aerial photographs have been interpreted and land use maps have been made over the period of 1954, 1969, 1974, 1986 and 1994 to consider anthropogenic forces of land use changes in rural Thailand. From aerial interpretation, we can classify land use types into two main land use types; forest land use and farming land use. From the land use maps of 1954 and 1994, the forest covers in mountainous area have been less converted to other types of land use than those forest covers in the flat areas. But forests in mountainous area have continuously degraded over the study period. On the other hand, forest land use in the flat area have been decreased gradually from 1954 to 1974, then forest land use in the flat area have been declined rapidly during the year of 1974 and 1994 while the farming land use has been increased. From the changes of forest covers in the mountainous and flat areas, it shows that the topographic factors are related to the changes of land use and land covers in the area. In flat area, increasing of households, in the two village, is an important driving factor of converting forest area to agricultural land. Therefore anthropogenic factor directly affects land use and land cover changes in the study area.
