摘要

Evaluating the transition of landscape can understand that ecosystem processes are being influenced by disturbance.For this reason,it is essential that using appropriate mapping techniques and quantitative methods to assess landscape conditionwithin different disturbance regimes.Landscape metrics were calculated for segmented areas of homogeneous land use in water-shed to allow understanding and characterization of ecosystem.Chen-yu-lan watershed,located in the central of Taiwan,is asensitivity area for disaster such as earthquakes and typhoons.In this study we focus on how the natural disaster affect land-scape pattern.The study shows that landscape metrics can measure the effect of typhoon and earthquake disturbance regime.The analysis shows that evaluating landscape transition can contribute more detailed information for managing ecosystem.
