Determine the Temporal Calendar Tourism in Lake Gahar Based on Model MEMI

today, the worth of the human basis of tourism planning. A difference in time-where climate in different regions a strong potential for tourism, and the reason is that Iran is a diverse country in the world tourism has five rows. A very beautiful area that has great potential in terms of ecotourism, protected areas Ashtarakoh and consequently Gohar Lake in the province. The level of comfort is influenced by environmental factors and physiological. MEMI model component models the thermal equilibrium thermo - physiological, the three sub-indices PMV, PET, SET formed, the basis of this model based on energy balance equation is based on the human body. In this study, in order to determine the appropriate time for tourism in the Lake Gohar Calendar of air drying temperature climate indices C, amount of cloud in the sky Acta, prevailing wind speed in meters per second, the water vapor pressure Hkto Pascal and relative humidity in percent synoptic stations city Dorud period 1379-1391, and parameters human physiological (age, Genus, weight, height, coverage and activity), as well as situational variables (longitude, latitude and altitude geometric study area), the model MEMI were evaluated. Calculate the comfort index for evaluating the results of this model suggest that PET and PMW output indicators are almost identical, and all year variety of physiological conditions in the lake is ruling Gohar. According to this model, the best time for tourist activity in the months of May, June, September and October are.
