Sustainable development, sustainable forestry, and forest ecosystem management are the main research topics of the 21st century. Achieving these goals requires not only detailed criteria and indicators but also incorporation of the concept of landscape in implementation. In this study, the demonstration forest of ecosystem management at the Lukuei Branch Station, Taiwan Forestry Research Institute was selected as the research site. This study was based on 2 different forest type maps (1996 and 1988) obtained using digital photogrammetry. GIS and fractal dimension were applied to investigate forest spatial variations, forest landscape changes, and the effects of human disturbances, such as cutting and forest roads, on forest landscapes. The results indicate that during 1988 to 1996, from the forest landscape structure perspective, the study area experienced a slight change in forest roads and obvious changes in plantation patches due to cutting for experimental purposes. Nevertheless, these changes have had little effect on the forest landscape based on an area-weighted fractal dimension. Considering human disturbances of cutting and forest roads simultaneously, however, the effect becomes more obvious. As a result, from the perspectives of spatial and temporal changes, the fractal dimension is a useful indicator for monitoring forest landscapes, and it can be applied by foresters in monitoring, planning, and analyzing forest landscapes.
