Tourism as a source of income and employment at the national level could be a strategy for economic development in the national territory. Tourism, especially at a time when profits are falling activity in other economic sectors, A good alternative for them and a strategy for development. On this basis, the main reason for the development of tourism over low wages and provide new employment opportunities and social developments in the local community. Conducting targeted research, demonstrate the carrying capacity (receive tourists) in Sistan tourist spots of steps to improve its capacity and that the Play Button What ways can be done. Methodology This study was descriptive and can be used to calculate the ecological, According to the formula provided by the World Conservation Union of Nature and Natural Resources and to estimate the carrying capacity of natural and cultural areas for tourism purposes two types of physical carrying capacity was calculated and real bearing. To analyze the information and provide tourism development strategy Sistan plain strategic model rides (SOAR) is used as a management complements the research pans growth and development of regional tourism plan is Hazrjht. The study area is the limiting factor Hurricane tourism, Shhrsvkhth a significant role as it is a tourist area. The results make it possible that with respect to the original planners of areas such as wetlands plain, Havmnatq semi-natural and historical wells around it would provide Sistan Plain tourism boom

The contribution of migration to urbanisation and urban population growth Internal migration, and net migration to urban areas in particular, drives the urbanisation of a country’s population. Rapid overall population growth often overlaps with rapid urbanisation, creating especially fast urban population growth. Rural-urban migration continues to attract much interest, but also growing concern. Migrants are often blamed for increasing urban poverty, but not all migrants are poor. In many cities, however, migrants form a large proportion of the urban poor with whom they share income and non-income disadvantages, including difficulties in finding adequate housing and in accessing services. Like the majority of the urban poor, they work long hours in low-paid, insecure and unsafe jobs and are exposed to a wide range of environmental hazards because most low-income and informal settlements lack basic infrastructure. In many cases when urban governments try to reduce or control rural–urban migration, this also affects low-income residents and not just migrants.This raises the question of whether policies that specifically target migrants in urban centres are desirable and possible.

In this research, we are present a GIS-based multi-criteria decision analysis approach to evaluating the suitability for industry site selection in the Kurdistan province in Iran. The multi-criteria decision approach considers different criteria which are standardized by fuzzy membership functions and combined by integration of fuzzy analytical hierarchy process (FAHP) and weighted linear combination techniques. The FAHP is used for the elicitation of attribute weights while WLC method weighting layers by use of obtained weights from FAHP and multiply in constraint elements. In preparation the restriction map, we combine different constraint element by union analyst. We used of increase and decreased linear-fuzzy functions to standardization the layers, and the Gamma operator is used for the overlaying these layers. We used of three levels of gamma operator for overlaying the layers, and we compare the three result map, then we recognized that the 0.5 of gamma operator is rational and optimum.in the final stage by overlaying gamma0.5 result map with restriction map we distinguished the suitable place for industry in Kurdistan province. As a result, 0.024 percent of total province area has the best potential to industrialization.

Firefighting station are one of the elements of public security in the city.to make them have the supposed role in public security; we should look at different urban facilities in detail and lend the city structure as a whole. Appropriate site selection of firefighting stations is one of the most important obligations of the city planners, which should be carefully planned and implemented. Better site selection is meant to avoid waste of resources in one hand and better capability of the stations on the other hand. In this research, best sites for the construction of new stations and moving of those stations with improper location in Tehran city has been studied. First, conceptual model of the study was defined, then, spatial layers and other information about site selection of the stations collected.in the next session Analytical Hierarchy process used to assign weights to spatial layers. This process was done based on the expert’s views and pair wise compactionmethod. After collection of expert views and in order to avoid wrong views, judgment compatibility amounts were calculated. After accepting of CR values, these weights used in future analyses. Network analysis, one of GIS spatial functions, used to find best routes from fire stations to affected area and service area of each station. Based on the analyses of this section and field checks, gave good attitude in terms of stations functionality. Regarding to the locations of existing stations, new stations proposed using a moving widow on the potential sites map.
