In order to determine the natural seasons in Iran, mean daily temperatures and relative humidity often stations during. 1961 - 90 period were analysed via pentad means. Application of Harmonic analysis to the pentad means showed a complete harmonic during year. At first, pentads were grouped by SPSS Clustering program. The clustering resulted in climatic classes in each station. Thermal characteristics of the resulted classes did not coincide with people’s common impression of the seasons, especially in winter. Thus, pentads grouped according to two winter threshold (10C) and summer threshold (22C).
The results showed only long summer and short spring in the Southern coastal areas. At the rest of the country, spring began generally in March and lasted about two months. Summer began as early as May 1st in South and as late as June 21st in the North and continued generally up to end of September all over the country. Fall season is short over the country and lasts about two months.
Winter starts about late October in the North and about early December in the South. The longest season is winter in the North (lasting about 5 months) and Summer in the South (lasting about 10 monthes).

This articl shows the Comparision of the aireal Photos from 1956 to 1996, plus the result of fieldwork research in recent years.
East of Hormoz Straite is examined here to discuss the change of rivers direction along the Caostal Plain deltas.
The research results represent that the frequency of change direction is increases from west to East. This Problem has correlation with Uplifting of Shore line Under the effect of active subduction of region.
In addition to that the place of change direction also related to this correltion and it is closer from west to east and to the Peak of deltas.
Therefore, it Seems that tectonic factor is the main reason of change direction and other factors have less impact on this change.

The attention to natural beauties such as Flowers and decorative Plants in Urban environments has been the Cause for greater Production and expansion of the activities of Tehran’s bazaar of flowers.
This change in recent years has increased the profit derived from our country’s import and export to 121 billion rials.
Tehran’s bazaar of flowers as a center for activities of functional system in exporting flowers has been the focus for examining the production procedure distribution of flowers as a result of transfering fruits and fresh vegetables bazaar to new area.
Examining the present system of production in regard to geographical and climatic possibilities as well as transfering the bazaar of flowers to the west bazaar of fruits and fresh vegetables have made apparent needs and priorities.
Thus the designation of spacial organization will both compensate for the short comings and play a vital rule in trading flowers

As explained in the first section of this paper, the Conventional methods are Used for converting the manual GIS maps to computerized GIS maps in most of related organization in Iran at the time being. Howerer, this paper presents the novel Approach based on intelligent approaches named Genetics approach.
This approach has more accuracy, better Resolution, faster response comparing with the conventional methods. this method also provide better Geographic symbole recognition for GIS maps.

The recent patterns of spatial distribution of triple ecomomic activities’ employments in Iran’s porvinces has been studied in this paper. Regarding the UN’s selection of nine coded employments and the rationale of this author, they are regrouped in here as three major classes of primary, secondary (maunfacturing) and tertiary activities. There are regional inequalities observed dominantly among the provinces of Iran concerning the structure of triple ecomomic employments. Although the spatial distribution of primary activities is geographically motivated, but the question of regional or provincial inequities would be considered carefully in view pointing of secondary and tertiary activites. The future regional and national planning of this country could be focused on the development of industiralization, specialization and diversification of the triple economic activities sturcturally. Of course, the associated efforts for provincial relocating of spatial distribution of triple economic activities would be requried.

The Dasht - e - Kawir (great kawir) in the center of Iran, is a coIlction of basins, which in general is divided into two main Hydrographical basins, Between them there are stretches an extensive area, which covering a lot of anticlines and several smaller basins. Physical features in the arid central basins of Iran are exterernely diverse and many have individual persian names.
One of the Eruopean researchers, says, ‘kawir denotes an expanse of slime or mud viscous rather than free flowing with frequent salt effiorescence, or continuous thick layers at the surface.” There are several theories as to formation of the Dasht-e-Kawir.
Dasht-e-Kawir is bordered by the marginal villages and towns, which there are many similarities in these area. The Sar-Kawir area in the north and Biabanak area in the south of the Dasht-e-Kawir, have been important in the past, because there are on the caravan routes loading north and south.
