Abstract
Recognition and understanding of landscape dynamics  as a historical legacy of disturbances are necessary for sustainable management of forest ecosystems. This study analyzed the effects of the accuracy during the analyzing forest dynamics and spatial-temporal changes in land use/land cover pattern in a sub-temperate like alluvial forest land with 32.660 ha area along the Eagan Sea coast of Turkey (İnegöl). This area is studied  by comparing LANDSAT images from 1987 to 2001 and evaluated with spatial analyses of forest cover type maps from 1972, 1993 to 2004 using GIS. The study investigated temporal changes of spatial structure of forest conditions over the period using FRAGSTATSTM software. The results showed that the forested areas increased both in 1972 and 1993 (3,61%), 1993 and 2004 years (3,37%), 1993 and 2004 years (7,10%) and between 1987 and 2001 years (4,74%). In terms of spatial configuration, forest areas are generally fragmented in the latter periods due to intensive forest utilization, illegal use, expansion of settlements and infrastructural development in the lowlands. Land use pattern significantly changed over time depending on a few factors such as unregulated management actions, social pressure and demographic movements. In conclusion, land use changes have developed in favor of forestry over time between 1972-2004 and 1987- 2001. The study analyzed accuracy between forest stand type map (accepted as ground truth data) and Land cover map produced from Landsat Image. Accuracy of supervised classification to determine cover type from Landsat TM (1987) 91% with the Kappa statistics (Conditional Kappa for each Category) value  of 0.945, Landsat ETM (2001) 91.04% with 0.9018 Kappa statistics value.
