Drought is a creeping environmental phenomenon that has many damaging effects on the economy, agriculture and society. Drought is a situation of shortage of rainfall and incoming temperature increases that may occur in any climate. This phenomenon is in parts of eastern central and southern of Iran, due to dry and semidry weather will be more. The geographic distribution of droughts occurred in the percentage of the country shows that the southern and eastern areas of the country s is more extensive, and whatever from the southern and eastern parts of the country took distance the intensity and frequency of drought is also reduced. The reason for this is the impact of subtropical high-pressure systems that significant amount of the rainforest of South and Eastern parts in the country towards the northern and Western parts of the significantly reduced and prevents the effect of Northern and Western systems in these area.Methodology Khorasan Razavi with 143864.118 Km2 is the fourth largest province in Iran. The highest point of the province is in the North of Nishabor with a height of Binalud heights 2116 m above sea level and the lowest point of the province is Sarakhs plain with a height of 300 meters above sea level which is located in Iran and Turkmenistan border. The average annual precipitation of Khorasn Razavi is between 75 to 390 mm. At the first data related to precipitation in the Razavi Khorasan Province was obtained from the country s water resources management organization. Precipitation data from 1980 to 2010 were averaged on an annual basis. This data is them prepared in note pad file, and by using DIP software, the index of SPI, PNI and ZSI was calculated for all situations. After the calculation of this indicator for each year, the data were entered into ArcGIS software and then used ordinary Kriging method for drought zoning for the end of the 11 years (2000-2010).Discussion and result The results indicated that changes in wet and drought year during WKH VWXGLHG SHULRG GLGQʼW IROORZ a regular process but changes in indicator are similar. Results also indicate that the year of 1992 and 2008 respectively are the rainiest and driest year during the studied period in all three indicators.The results of drought indices zoning of PNT, ZSI and SPI in the period of case study suggest that changes in different years and parts of Province does not follow the regular process. The result of drought index zoning in Khorasan Razavi Province suggested that PNI drought index made the condition wetter and ZSI drought index drier. Also the results show that drought index SPI and ZSI
