Aiming at identifying the key factors which may affect the future status of Tehran Province spatial planning, this study was conducted with a future studies approach. This study is an applied study in terms of targeting strategy and its methodology is of descriptive-analytical and regarding the future studies methods it is an explanatory one. Following the Delphi method, the theoretical and practical data have been collected using documentary and survey research techniques, respectively. To carry out this study, a total of 20 urban experts who were professional in regional, spatial planning areas were chosen based on purposive sampling method. MIC MAC was used to analyze the gained information from Delphi methods and to carry out the cross-impact analysis. The results of this study indicated that the dispersion of key and effective variables of the future status of Tehran Province spatial planning has an unstable system. The study also showed that out of 64 examined factors in this study, 22 key factors may affect the future status of Tehran Province spatial planning. A great deal of such key factors has been concentrated in the effective and double variables group.

Among the many factors influencing the wheat production, environmental conditions and climate are the most important variables that need to be scrutinized. According to the talents and capacities of wheat production in the city of Shush, according to the 12 year comprehensive review of climatic and environmental factors were identified. Then based on Boolean logic in GIS environment between any of the environmental and climatic parameters were studied in wheat. Finally, wheat prone areas were identified in the city of Shush.The results indicate that the city of Wheat cultivation, favorable conditions and has the talent is, But culture is made of wheat and wheat growing areas of the north and northeast of the city, the best place for you is.

One of the most important factors influencing human life is the weather. The aim of this study was to investigate the spatial temporal features of the occurrence of thunderstorms in the southwest of the country. States (Khuzestan, Chaharmahal Bakhtiari, Kohkiluyeh and Boyer-Ahmad) During a statistical period from 1985 to 2015, And then the analysis of the synoptic conditions of the thunderstorms obtained from the synoptic stations of the region. The results of the annual analysis of the frequency of thunderstorms at Dezful station with 479 phenomena and Ramhormoz with 252 events have recorded the lowest in the stations. And in the seasonal analysis, the highest hurricane occurred in the spring with the number of 137 and in the summer with the lowest storm with the number 10. In the monthly analysis of the frequency of thunderstorms, April was the most 75 days and August was the least with 2 days. In terms of the frequency of thunderstorms during the eight-hour observation period, the highest frequency of the thunderstorm is 12 o'clock (3.30 o'clock).

This study aims to investigate the role of heat island in the process of temperature changes in an urban area of Tehran during 2010 and 2018, equivalent to 1389 and 1397. To evaluate the changes, five points were identified on the map of region 1 and its eight regions. Then the middle month of each season from 2010 and 2018 was selected for review. Landsat 8 satellite data were used to analyze the heat island and the effects of urban construction on the intensification of this phenomenon. The maximum temperature data, normalized vegetation difference index, and ground surface temperature were extracted. This study shows that the level of vegetation in 2018 compared to 2010 has decreased sharply, so that it has caused temperature changes and also the creation of a heat island in recent years in the region. The increase in temperature in the morning and noon is observed in all selected months of the four seasons of the year. At the same time, the amount of increase in minimum temperatures was greater than the maximum temperatures.
