Abstract

Temperature changes leave undeniable effects on the level of evaporation and perspiration, hydrology cycle, sustainable agriculture and water consumptions. A major part of our country including the zone under study is located within the limits of fragile ecosystems of arid and semiarid zones throughout the world. Life, activity, planning and management of limited resources in these zones require knowledge and capability to utilize facilities as well as accuracy in operation method. Change of climatic conditions and especially temperature increase impose destructive effects on economic, social, agricultural and livestock breeding structure of the aforesaid zones. For this purpose, anticipation of temperature and its changes are specifically important. Mean, minimum and maximum data for synoptic station of ZAHEDAN from the establishment until 2010 were received and used to anticipate the temperature of the station and its effect on the level of evaporation and perspiration. Static and normal natures of data were tested by Q-Q charts and AUTOCORRELATION and partial AUTOCORRELATION-correlation functions. The data was changed to normal and static data by using appropriate differentiation changes. Mean, minimum and maximum TIME SERIES of temperature for each station were then anticipated. Accuracy of the model was assured by partial AUTOCORRELATION and functions of model remainders. In addition, validity of the model was assessed and approved by actual data of 2010 and 2011. Model (0, 1, 1) (1, 1, 1) was identified to anticipate temperature in ZAHEDAN station. The effect of temperature change on the level of evaporation and transpiration was measured through calculating the potential evaporation and perspiration of the station using CROPWAT software and Hargrives method. Research results showed that all temperature parameters increased over 1.3oC especially in March, June and August and averagely about 0.9oC in December and January. As the result of temperature increase, level of potential evaporation and perspiration in the aforesaid months averagely increases about 0.22 and 0.08 mm per day. This severely affects water consumption in different parts.
