Continuous decline in Lake Urmia water levels In recent years, the decline of rainfall and river flows and constant droughts has become the main concern of the people and the people. To study climate change and increase of temperature in the catchment area of ​​Lake Urmia, two factors for measuring the temperature and properties of satellite images were used which indicate the importance of land surface temperature changes (LST) and normalized vegetation differences (NDVI). This study was carried out using the satellite data of the periodic watershed (2008-2008) to investigate the spatial relationship between NDVI-Ts and NDVI-ΔT to investigate the actual agricultural drought occurrence. The goal is to extract the VTCI (vegetation temperature index) index, which is capable of identifying drought stress at regional scale. The results showed that the slope is negative for the warm edge, where it is positive for the cold edge. The gradient gradient shows that the maximum temperature is reduced when the NDVI value increases for any interval. The slope on the cold edge indicates that the minimum temperature rises when the NDVI value rises. Overall, at the warm and cold edges, it has been observed that the drought trend over 2009-2008 is higher than in 2010. In the days of Julius Day 257, the slope of the cold edge from 2008 to 2010 is decreasing. But at the hot edge, intercept pixels for 2008 is more than 323 degrees Kelvin, where in 2009-2010 it is less than 323 degrees Kelvin. In general, the correlation coefficient (R2) is different in the TS-NDVI spacing between (0.90-0.99). The present study showed that with the integration of satellite satellite data with meteorological data, the VTCI threshold for drought stress varies from year to year depending on the data conditions.

Considering the factors affecting the conversion of places and destinations to the tourism brand of the prevalence of tourism development in each region. Because these factors play an important role in the conversion of tourism destinations, and on the other hand, the conversion of a destination to its tourism brand is also a factor in developing more tourism in purposes. Considering the importance of this issue, the present study aimed to investigate the factors and stimuli effect on increasing the transformation of urban and rural areas to tourism brand in Guilan province. The present research is in terms of purpose, applied and method of doing it. The data collection tool and the questionnaire and interview information. The statistical population of the research is experts and tourism specialists in Guilan province, using targeted sampling method, 50 experts were selected as samples. To answer the research questions, the binary logistics model and qualitative analysis were used. The results of the research indicate that linear and meaningful communication has existed with the factors and stimuli of the research with the conversion of urban and rural places to the tourism brand. Also, the results showed that among the five factors in question, three factors of diversity of job opportunities, culture and natural assets and local infrastructure have had the most effects on the transformation of urban and rural areas in Guilan province for tourism brand.
