چکیده:
Climate is an important part of a region’s tourism resource base. Weather and climate information
is of interest to both tourists and the tourist industry. Information on climate is useful for planning
vacations.Processing information associated with tourism and a new era in human interactions,
social and cultural structures, especially in urban areas the figure is estimated. Natural features of
a place are considered as a bed for creation and extension of habitat, recognition of living system
capabilities will be helpful as a guideline in future tuorism planning and elimination of limits and
obstacles. Natural features of a place are considered as a bed for creation and extension of habitat,
recognition of living system capabilities will be helpful as a guideline in tourism planning and
elimination of limits and obstacles. The region of our study is situated on the high level of central
Alborz. This region is extended from 51˚, 225' to 51˚, 43' in eastern wing of Greenwich Meridian
and also 35˚, 47' to 36˚ in the north of equator. Above position includes special climate because of
height effect, some of its features are semi mild summers and cold winters and also its variation
slope is lower than 1 degree. However Jajorod and Ahar valleys have a great effect on region's
ecology but this region is a combined area of mountain and valley. So, height differences affect on
temperature variation and slope effects are quite obvious in this region. Besides Jajorod river,
earth slope is various from 5 to 51% and a town, Darkia, around this complexity. Generally
Geographical directions related to warm and cold slopes,extended in all four main direction
(south, west, east and north), can influence on the construction of effective tourism planning. This
study presents the initial ecological studies in this field, moreover, people are more sensitive in
weather changes and ecology situation, so the more we inform about these effects, the better we
can manage daily activities. This research attempts to identify the role and factes of tourism
climate their significance and impact & impact of natural environmental factors, particularly
climatic elements such as effective temperature, rainfall and topography on the physical
development, physical cities, particularly cities in the region like, Oshan and Fasham. In this
article, analytical methods, field and library have been used and the results show the most
important factors which affect normal physical development (tourism activite) such as temperature,
ice, rainfall and topography. This research is based on effectiveness in tourism climatology data
over a period of 12 years, the region's tourism potential areas of Iran and Tehran Oshan and
Fasham, which is based on studies of descriptive - analytical using data collected from local
weather stations
