Abstract
Inner Mongolia belongs to arid and semiarid area, with little and unevenly-distributed precipitation , hence drought is the major natural disaster .In order to reveal the characteristics of temporal and spatial distribution of drought occurrence in different areas of Inner Mongolia , survey and analysis are conducted of the data of precipitation and damage caused by drought to agriculture and animal husbandry in 101 counties of the region during 1990 ~ 2007 .By using the methods of statistic calculation and frequency analysis , the characteristics of temporal and spatial distribution of drought occurrence in the region are found out , including the frequency and distribution of areas and seasons (spring , spring~ summer, spring ~ summer~ autumn)prone to occurring drought and levels of drought(severe , moderate , mild). These results may serve as reference for the prediction and forewarning of drought , reduction of damage and planning and allocation of limited water resources .
