Factors of the natural-ecologic, social, economic, historical and political environment affects formation, establishment and organization of rural environments. Thus, the present article seeks to clarify the influence of natural elements (natural-ecologic environments) in transformability of spatial organization in 11 rural districts of Lavasan-e Kuchak village. Descriptive-analytic methods and secondary-research methods are used for collecting information. Moreover, models like Gatman institutional measurement, value of centrality, total minimum distance, number of direct links, number of communicative nodes and demographic capacity are also considered. Results indicate that natural elements, especially topography, water resources and slope have influenced the position of rural settlements. This has resulted in the spatial organization of the study area possessing a two-level hierarchical structure. Moreover, based on the results it is suggested to form spatial organization of the area with three rural areas of Afje, Kantiya and Bujan villages and a rural complex of Lavasan city.

The present study describes and compares the spatial method and spatial statistics by a combination of different methods of science in different fields such as multiple criteria analysis of GIS. The ultimate goal of this method is to assess the appropriateness of the area in question in order to determine the optimal location for landfill. In this context, the first step is the formation of a hierarchical structure of multiple criteria. Next, it is using the spatial analysis process to establish evaluation criteria, these based on the laws of Greece and the European Union, and also on the basis of practical and feasible international guidelines. The relative importance of the assessment criteria is determined based on the hierarchical structure and, using simple weighing model, suitable sites for landfill in the study area are determined. as a result, suitable locations are ranked from 0 to 10, which is from the lowest to the best, respectively. The last stage is the process of spatial clusters, which are designed to represent the most appropriate area. The initial ranking permits the selection of suitable places for burial from among existing places. The application and implementation of the proposed method on the Lemnos island in the north of the Aegean Sea showed that 9.3% of the studied area was suitable for burials above the 9th level.
