| 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 occur
rence 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 predicti
on and forewarning of drought, reduction of damage and planning and allocation of limited water resources. |
