Abstract
Based on the data of the climatic, maize growth and development, and the yield from 23 meteorological stations throughout the Xiliaohe watershed during 1961 and 2010. The whole growing period of maize was divided into three stages, early stage(from seedling to tasseling stage),medium stage(from tasseling to milk-ripe stage)and later stage(from milk-ripe to mature stage). According to water deficiency index to divide the level and hazard assessment model of drought and flood. In addition, spatial distribution of hazard in Xiliaohe watershed can be analyzed using the IDW method. Conclusions are as follows: (1)water deficiency index of maize in the early stage is on the rise but in the medium and later stages are on the decline. (2)The frequency above drought decrease from northwest to southeast in the whole stage, above medium flood increase from north to south in the early stage and later stage, and decrease from middle region to all around in the medium stage. (3)There are obvious regional differences about the hazard of drought and flood in Xiliaohe watershed.
