Nasiri, Alireza | CHehraghani, Abolghasem
Nowadays, spatial spread balance in resources and utilities between cities is one of government aims. Utilities spreading balance is binded to their sites in order to all people can access them easily. On the other side, Land Surveying's main goal is regulating human activities in national environment to reach rational exploitation of resources and land capabilities. This goal could be accessed via GIS and its ability in various contexts. In this paper, we focused on spatial spread of Gas industry infrastructures, especially CNG stations in Qom province. First, we evaluated existing CNG cites. We designed special questionnaire containing questions about CNG station's quality, quantity, spatial and services. The forms were filled with drivers and we analyzed them. Also we used GIS to implement CNG cite standards and analyzed existing stations. Also we determined optimal places for CNG station using GIS. Our model includes AHP for weighting layers, a way that uses comparative methods for weighting, and Index Overlay for combining layers with AHP weights. Finally, we categorized Qom province in six categories ranging "Very Unsuitable Sites" to "Very Suitable Cites" for CNG station.

Dalir, Hamid | Ramezanzadeh lasboyee, Mehdi
The geomorphology is an important branch of natural Geography that its goal is promotion of human life, ultimately. The geomorphic processes have considerable impact on human life, and opposing, human activities and behaviors have its impacts on the geomorphologic units and geomorphologic processes, enhancing the above argument. The Gilan county, at its geographic position; embraced by two structural units; the Alborz-Talesh and Caspian sea, appears as a very good open space of morpho-dynamic formations and features. People of this region, on the track of new cultivation and industrial technologic products introduced, initiated a great changes in the Ecosystem, and due to low knowledge of Epigenic flow activities and sea level fluctuations of Caspian sea, they bother toweling and housing in the interior and exterior borders of the sea and rivers. This low knowledge of action and contractions of surrounding natural environment caused huge, bodily and financial damages to them in these hazardous yards.

Today, the expansion of urbanism has led to many problems for various countries in the world, especially developing countries. Iran is one of the developing countries that in recent years has faced numerous damages due to population increase, especially in urban areas. In recent years, countries in the world have tried to overcome the problems deriving from unsustainable urbanism via using sustainable urban development. Accordingly, the authors carried out this study to determine the similarities and differences among sustainability evaluation systems existing in developing and developed counties and explain the needs of developing countries, like Iran, to improve management of urban areas. Therefore, in the study at hand, the global urban sustainability indicators such as BREEAM Community، CASBEE-UD، GBI Township، LEED-ND، IGBC Green Townships، GRIHA-LD، Green Star, and IUSAF were examined and were compared with the intended system in Iran (IUSI). In this process, the similarities and differences of selected evaluation systems were compared with each other in terms of type and importance level of indicators. The obtained result showed that the urbanism challenges in various countries in the world are different based on the development level and environmental, social, economic, and geopolitical conditions. In addition, the most important indicators of urban development measurement in developed countries were identified as energy, resources and social welfare, smartening, and environment, while the prioritized indicators in the developing countries were determined to be planning and developing the society, managing infrastructure resources, transportation, local security and economy, employment, and – mostly importantly – access to healthy water. Moreover, the findings of this study indicate that via localization of the systems and indicators related to sustainability evaluation for every country, region, or province, a more precise evaluation can be attained. This can offer great assistance to future planning to advance the sustainable development goals.
