One of the drought atmospheric phenomena that can in any area done and led to major losses economical, social and environmental. This phenomenon from various sectors of environmental, including the ground water resources during the period of its sovereignty. Effect Drought on groundwater resources far less attention. In this study using the SPI index and the water table level underground standard ( SWI data ) affected by the drought on underground water resources the Yazd ardakan blue years 82 1381 to 91 1390 for all existing wells and long term statistics for 8 basin has been selected. in the intensity of the spatial . In examining the spatial distribution of drought severity of the decline in the aquifer using map sowftward Gis. The drought in the stations studied were determined by Mann-Kendall. The results showed that in the year 79-1378 and 87-1386 in the water during the worst drought in most of the stations were located. It also examines the impact on the level of ground water hydrological drought of SWI index is used.
