land use planning, refers to how to use, distribute and protect the land. this type of planning can be considered from different perspectives, such as sustainable development perspective view is one of important land use views. in this paper we have tried to study and evaluate the land use change of maragheh city from sustainable development perspective, and study the harmony or disharmony with...

One of the most important problems facing desert areas today is the growing trend of desertification and land use change. Land use is a special use of man from the earth. These uses are changing over time and these changes lead to increased land degradation and ecosystem destruction, especially in arid and semi-arid regions. Accordingly, in this research, the trend of land use change in the eas...

Production and prediction of land-use/land cover changes (LULCC) map are among the significant issues regarding input of many environmental and hydrological models. Among various introduced methods, similarity-weighted instance-based machine learning algorithm (SimWeight) and Markov-chain with lower complexity and proper performnce are frequently used. The main aim of this study is utilizing Si...
