Our purpose in this paper is to emphasize the theory of "the effect of the role of place on the spatial distribution of phenomena", whether problems or opportunities. In almost a year, COVID-19 has disrupted people's lives in Iran and caused minor to large damages in various aspects of citizens' lives. The outbreak of the disease in the metropolis of Tehran, given that it is the capital of Iran, is however more worrying than other cities in Iran. Therefore, the importance of this research is that it tries to provide hypotheses that explain the reason for the increase in the incidence of the disease by emphasizing the role of place in some districts of Tehran and by statistical analysis and preparing a questionnaire and questions from the elite and Executive experts and citizens in different districts of Tehran have been trained. The results showed that there was a direct positive correlation between the role of place (economic, cultural, political and environmental) in the 22 districts of Tehran and the increased population and increased number of coronavirus-infected people. According to the evaluation of the performance (role) of each district in Tehran, districts 11, 12, 17 and 20 had the most economic places (bazaar and mall), as a result the number of coronavirus-infected people was higher in these districts. The political places are in the next place. The districts where most political places were located were 8 and 11. Areas with service and cultural places such as passenger terminals, subway stations, universities and hospitals were the last in exposing to this virus.
There is growing evidence that projected climate change has the potential to significantly affect public health. Many of these effects are likely to be exacerbated by the risks associated with exposure to heat, floods, and chemical and biological pollution in cities. Identifying the effects of climate change on the environment, and the risks and opportunities of adapting to mitigating climate change can help city policies and planning. The stability of urban systems may be jeopardized if appropriate measures are not taken with the urban climate in the field of environment. Studies show that urban life has always been closely related to the natural environment. One of the most important natural factors involved in the typology of cities, which has a very influential role, is climate. In fact, the characteristics and conditions of geographical spaces, especially cities, are due to the natural and abnormal natural possibilities and limitations of natural geographical factors. Because the city originates from the mathematical and relative position, natural factors, especially climate, have a great impact on the typology and natural and human characteristics of cities. In this fundamental article, a descriptive-analytical method has been tried to examine urban space policies with emphasis on the environmental field. The question that arises here is what effect does climate change have on the type and method of policy- making and policy of urban managers in the field environmental? The results show that cities are climatically divided into desert, mountainous and coastal cities that have their own economic and social characteristics. Since environmental issues in any country are largely due to natural conditions and the characteristics of the human environment, knowledge of natural geography and an understanding of the dialectical relationships between the environment and humans are important for analyzing geographical issues. And has a significant role in managing space policy, especially urban space.
The environment in which we live greatly affects our health. This paper aimed to analyze the environmental factors influencing health in Hashtpar, a medium sized city with a population of about 53000 people, located in coastal plain of northern Iran. 14 indicators were included in the dataset and it is used one or a combination of 2 or more methods to generate a mean value for any of the indicators in any of the supposed 34 data collection points. The data entered into Arc Map 10.8 (GIS), then, zoning maps were produced using the Kriging interpolation tool in GIS. Findings show that generally, healthy environment indicators are higher than average level and the indicators are in better condition in central parts of the city than those in outskirts.
