        Thermal energy recovery technologies which used to burn solid urban waste are one of the relatively new and appropriate methods in waste management. Heat and gases are generated by burning waste that can be used to generate energy. In this research, a decision model based on the Analytic Hierarchy Process (AHP) method is Provided to select the best thermochemical system based on three technical, economic and environmental criteria. In this study, waste incineration, gasification, pyrolysis and plasma systems were evaluated. Collection of required information was obtained by reviewing reliable sources and preparing and completing questionnaires. The study area in this study is Mashhad city. The results of this study indicate that among the studied systems, plasma system (technology) is the best option for energy recovery from solid wastes in Mashhad, after that, waste incineration, gasification and pyrolysis systems are in the next categories, respectively.

        In this regard, with the aim of studying the rural spatial organization, the present study seeks to first determine and form a hierarchy of settlements that can be an effective framework for the distribution of services and functions at different levels, and finally the prevailing spatial pattern in Identify the area. Therefore, in order to achieve the objectives of the research, using the centrality index and applying 35 variables, the studied settlements were classified at different functional levels (5 levels). It is noteworthy that the present study is applied in terms of purpose and based on descriptive-analytical method. The method of data collection is due to the nature of library and field research. Geographical territory of research is Zebarkhan village of Neishabour city. The findings of the study indicate that the lack of proper distribution of services and lack of spatial balance has increased mobility and movement between human settlements in the countryside. Hence, the two settlements of Ghadamgah, Darrud, have become the main places of intra-district traffic with the first ranks. Meanwhile, the villages of Bazhidar, Aliabad, Cheshmeh Khosrow, Mohammadabad, Qaredash, Qarebeik and Kalateh Lavidani are at the lowest level of development (deprived) and lack the minimum services and facilities.The results indicate that the pattern of flows is one-way relationships and no complementary, two-way and synergistic relationships are formed.
