摘　　要：近年,江汉平原受旱涝灾害影响日趋严重。利用监利水文站1954-2010年的月降水资料并结合SPI模型对江汉平原的旱涝分布及其变化规律做了典型性分析和研究。结果表明：运用SPI模型分析得到的监利地区多时间尺度的旱涝分布及其变化规律与实际基本相符。即该地区旱涝灾害频繁且呈交替发生。将SPI模型应用于旱涝分布及其变化规律的研究具有很好的实用性。In recent years, the Jianghan Plain has been affected more and more seriously by drought and waterlog. The monthly precipitation data of the Jianli Station from 1954 to 2010 were used to analyze the distribution and variation law of drought and waterlog in Jianghan Plain based on SPI. The results agree with the fact that Jianli is suffered with frequent droughts and waterlogs which happened alternately and SPI is suitable in studying the distribution and variation law of drought and waterlog.
