Abstract :

Abstract Change and destruction of the environment by human activities, has been increased that results can be pointed out to the landscape change. This paper aims to determine the best scenario to protect and restore land cover changes in the future with an emphasis on the patches connection of natural vegetation. Predict the ecological impacts of management scenarios based on metrics values determine and then the best scenario-based TOPSIS method was selected. In addition, the implementation of the scenario of protection and restoration in the watershed Tajan will be reduce the number of patches from 7600 to 4657 patches in natural vegetation and will cause better connectivity that is a sign of decreasing degradation and fragmentation of the landscape in the study area. The approach used in this study the possibility of predicting the ecological results of land use for achieve the objectives of the assessment and better integrated management of the watershed changes provides.
