Background and Aim: Rising temperatures in cities are one of the effects of direct human intervention. The thermal island of the city is due to the characteristics of urban planning, air pollution, human heat, and the existence of impermeable surfaces in the city. In the meantime, recognizing the effects of heat islands on the psyche of people is very important. The purpose of this study is to study and identify the heat islands of Ahvaz according to the pattern of air pollution.Methods: This research is applied in terms of purpose and in terms of descriptive-analytical methodology based on spatial studies approach and analysis of satellite images. To identify and analyze the heat islands of Ahvaz, satellite images were used during 5 periods from 2001 to 2017 and processed using software (ENVI). Also, data related to the air pollution index (AQI) in the city of Ahvaz was used in a period of 7 years from 2010 to 2017. In order to identify the areas with the most pollution, the network analysis process (Network Analyst) has been used in the ArcGIS environment.Findings and Conclusion:The results of this study show that southwest of Ahvaz Due to the multiplicity of polluting centers such as oil and gas refining centers and industrial towns, the pollution center of this city is considered. The results of the questionnaire analysis also show that the Heat tolerance threshold in the city of Ahvaz in the first place reduces the increase in stress and daily pressure in people and then reduces happiness and freedom and reduces the feeling of life satisfaction will follow.

Landslide is always a serious threat to human settlements. In the Face of such accidents, little can be done at the moment of occurrence. Before that, its effects can be foiled with planning and for reduction of possible casualties and damages. The aim of the present study is to take a systematic look at natural hazards, including Landslide in order to draw up a scientific and accurate plan outlining for preparation and planning based on the use of spatial information systems and multi-criteria decision-making models in line with the zoning risk landslides and determining the direction of residential development is predictable. The present study extracted 15 effective criteria in landslide risk. Then using of the results of the evaluation of two models of (DEMATEL, FUZZY hierarchical analysis process) showed that the DEMATEL model is in accordance with the principles and laws of mathematical and has more certainty. While the process of FUZZY hierarchical analysis was only consistent with the knowledge and expertise rating. In the risk zone whit the DEMATEL model low risk, zones %37/1 (190/39 km2) it has the largest area of 513/12 square kilometers, have most area of surface. Also, high risk zone with %2/32 (11/89 km2), high and medium risk zones each with %34/33(176/13 km2) and low risk by 134/71(%26/25 km2) were next in the ranking. Zoning and risk with FUZZY hierarchical analysis, risk zone of very small allotment, %36/53(187/43 km2) and low risk zone of %17/73(90/96 km2) and medium risk zone %17/79(91/27 km2), and high risk zone of %16/84(86/41 km2), as well as very high risk zone%11/2(57/6 km2) were ranked.

Today, the challenges of modern urban life and environmental and social problems have led to a futuristic approach to urban planning and the use of various tools to build a desirable future. The present study uses the technique of cross-impact analysis, which is one of the common methods in futures research, and using Mick Mac software, has analyzed the components of urban development in the metropolis of Ahvaz. Then, 37 components were extracted as indicators of urban development using the Delphi method. The results indicate that six categories (influential factors, risk factors, purpose, influential factors, and independent factors, regulators) can be identified in the scatter page. Finally, among the 37 key factors, after examining the impact of these factors on each other and the future situation of the metropolis of Ahvaz by direct and indirect methods, 13 effective and key drivers were identified, including; (Population, equitable distribution of urban services, development of tourism industry, organization of special tourism axes, organization of suburban areas, control of air pollution and promotion of environmental health, expansion of public open space and creation of leisure centers, providing the appropriate level of economic growth, improving quality of life in dilapidated urban fabric, organization, and improvement of worn-out fabric, expansion of small and high-yield workshops, empowerment of non-governmental organizations, development of recreation and tourism centers) which have the most role in the future state of urban development in Ahvaz, were selected as factors and drivers Affecting the urban development of Ahvaz. The results further show that the factors of "development of the tourism industry, organizing the suburbs" are at risk. Population factors, fair distribution of urban services, development of the tourism industry, will have the greatest impact on the urban development process of Ahvaz metropolis.
