Abstract:

With the increase of fossil hels and accumulation of the contaminant gases in the earth atmosphere due to the worldwide development of vehicles and industries during the recent century, the greenhouse effect has evolved in which the earth heat and reversal high waves can not exit fiom atmosphere and subsequent to which the earth temperature has risen to one degree or two. Universal studies have leb many of the scientists to believe that the phenomenon of temperature increase has been also observed at some meteorological stations in Iran, indicating a tendency to a drier climate. This paper has been designed with the theory that climatic variations in Iran have been influenced by the ecological instability and have altered its natural system. Making use of the statistical, descriptive and attritional methods, the research deals with the analysis of climatic variation influences and the relevant susceptibility specially resulted in the recent decades: The growing process of droughts. The development of deserts and desert growth. The progressive increase of floods. The research attempts to analyze each of the above mentioned variations and offers appropriate strategices for them.
