In this study, spatial variation of soil texture was assessment in the Farahan plain, Markazi province, using Kriging geostatistical method. First, 52 samples from different points in the plain was prepared. Then descriptive statistics for data were determined using geostatistical analysis in ArcGIS 10.3 software. Then Kriging method was used for determination the spatial variations. Regarding the results of evaluation criteria, Kriging model had an acceptable efficiency in zoning for soil physical properties variations. So that values of evaluation criteria are close to one. On the other hand, spatial correlation was high and in all models it was less than 0.25. According to the results, soil intrinsic properties, climate and land use were effective in soil texture changes in Farahan plain. It is important to pay the attention land use in soil projects.

The changes in life have created problems in different countries. These problems arise from the mismatch of the needs of urban populations with the capacity of urban management in response to them And since the city has a dynamic inventory, it needs integrated management. The purpose of this research is to analyze the criteria for integrated urban management in Tehran. The research method is descriptive-analytical and is used to collect information using a library method. The statistical population of this research includes the employees of Tehran municipality and according to the wide range of statistical population, cluster random sampling method was used. And the information provided has been analyzed using the Delphi method and the Tapsis technique and has therefore been ranked in the criteria. The criterion of the legitimacy of managers in the integrated urban management structure with a score of 0. 735193 won the first place.

Today, tourism is the most prominent and most efficient economic activity that can bring many economic, social, political, and cultural achievements to its pioneers. This phenomenon is now recognized as one of the foundations of globalization and a hallmark of space-time condensation. Historical tourism, which incorporates the old and ancient texture of cities, has a significant impact on the spatial and functional structure of a city. Therefore, the purpose of this study is to plan a strategic tourism development in the historical city of Khorramabad. The methodology of this research is descriptive - analytical based on documentary and field studies using the SWOT model and then the proposed strategies are calculated using quantitative matrix method (QSPM). The results of the research show that invasive strategy (SO)‌(utilizing maximum strengths and opportunities) with a score of 3.42 in the first priority and competitive strategy (ST) (avoidance of threats and the use of opportunities) with The 2.63 points were identified as the most important strategies for the development of the historical context of the city in the second priority.

One of the necessities to stop the unrestricted and unruly growth of urban blocks in inappropriate directions is designing suitable environments in order to produce urban green network areas to develop the quality level of city life. The city of Karaj has faced an increasing number of citizens due to the immigrations and geographical alterations. This increasing population will result unbalanced expansion and inappropriate city development. The effort in this article has been to identify different zones of Karaj district and giving out a suitable urban green network area by studying all the plans of the current situation of the district, analysis of the data and considering the effective characteristics of the area to reach an ecological balance and a systematic urban green area. This was done by using Gis software.

Nowadays many of governments, don’t give a lot of credit to developed organizations and seek better risk management. The present study aimed to investigate the role of drought risk management in reducing the vulnerability of socio-economic in rural settlements of nagadeh.In the analysis of Friedman test methods, T one sample, path analysis and Pearson correlation coefficient was used.The results showed that the vulnerability of rural settlements have seen the most demage after the occurrence of drought and risk management based on economic, social and socio-economic aspects could have an important effect in reducing rural vulnerability with average of 3.75. on basis of path analysis economic and socio- economic aspects of risk management with /528 - /363 coefficient have direct impact and social aspects have indirect impact in reducing economic and social vulnerability with /198 coefficient. Therefore, it can be inferred that drought risk management as the most sensible approach is to reduce vulnerability and at the operational level should be done participatory, flexible and Situational

This study analyzes the spatial distribution of population among districts in Ahvaz by ranking them. The research way is descriptive analytical models and taxonomy, SAR, SAW, entropy , Kapland and borad index is used. The population is eight area of Ahwaz metropolitan. Ahvaz city, according to latest census of 1390 the population was 1112668 and intern of distribution and access to municipal services, population growth is not appropriate. The correlation coefficient obtained with a value of 0.619 indicates that the distribution and population density in the city of Ahwaz, there is a weak relationship. Combining the results of the model show in 1 area looks increase in population and in region 6,7 and 8 in order to increase the level of coordination between the needs of the population and service so we can say with a balance distribution of service across metropolitan areas in Ahwaz according to the needs of population can reach a balance in urban areas. Therefore, the relationship between the distribution of the population and services in eight districts in Ahwaz to achieve sustainability and social justice seems necessary.

Geomorphotourism and geotourism is Responsible approach, conservation and scientific phenomena is unique in terms of identifying geomorphosites To sustainable socio-economic development of local communities and is traced the protection of geological heritage Combining the fields of cultural heritage, history and ecology of the high potential for sustainable tourism offers. This article tries to focus on the best available research and arid desert areas of the region maranjab Choose from eight types of tourism development and the processes of desertification and desert selected geomorphosites ability to evaluate geomorphosites this area. In this context, the use of assessment methods based on the evaluation of the 5-fold scientific, cultural, aesthetic appearance, economic and administrative potential of the area is evaluated using field survey. The results showed that, the desert and desert maranjab due to its tourist attractions, are now in need of structural and management of tourist services with an emphasis on the formulation of conservation laws. While some such geomorphosites lake terraces, more feature-based comparison of the positions nbka, barkhan and new approaches are geotourism. Which requires the separate programs.

This research aims to study the performance of municipality and its effect on the urban living environment permanency of area number 2, of Ahvaz. The sample size (N=97458) was maintained as 384 people using the Morgan table. To determine the questionnaire coastal in this paper, we used the Kronbach Alpha and the coastal coefficient was 0/84.To examine the theories,we applied the average comparison test. The results showed that the average performance of Ahvaz municipality in area number 2 regarding the urban living environment permanency was rated 3/56 with the scale deviance of 1/68 .The average comparison test results show that the meaningfulness stages of all the scales were below 0/05 . Then, to rate the role of municipality in improving these 8 indexes, we used the Topsis model. And with the use of prioritizing that we got by applying the Topsis model, the green areas, soil, and sonic indexes with the average priority coefficient of 0.50 were the highest scales affecting the role of urban management, while the sewage index with the coefficient rate of 0.25 and Transportation, polluting jobs and water pollution with the coefficient rate of 0.08 in priority followed as the average and lowest scales, respectively.
