  Today, the importance of water in maintaining life, especially in arid and semi-arid areas, is not hidden from anyone,.. There are various techniques to determine evaporation and transpiration, which include the use of empirical formulas, lysimeters, remote sensing and satellite methods. It is micro-climatic technologies and methods of using plant transpiration coefficient. This research started in April 2014 and was completed by the middle of September 2014. Studies were conducted on three species of bay leaf (Laurus nobilis L.), rosemary (Rosmarinus officinalis L.) and oleander (Nerium oleander L.) located in the parks and boulevards of all 9 districts of Shiraz municipality. To calculate the rate of evaporation and transpiration of the target plant, first the rate of evaporation and transpiration of the reference plant was calculated using the data of the Shiraz synoptic station and the standard Penman-Mantis-FAO method, and then the coefficient (KL) was calculated based on the California method. This coefficient is the key factor in estimating the water requirement of green space. The highest rate of reference evaporation and transpiration is related to the months of August and July, respectively, and the lowest is related to the months of Bahman and January. . The highest water requirement is between June and October. In order to solve a large part of the lack of water resources mentioned, methods such as recycling and reuse of returned water, using non-conventional water sources (sewage, sewage, gray water, etc.) and surface water and runoff are suggested as solutions.
