摘要: 合理的汛期分期,可以为汛限水位分期控制提供科学依据和技术支撑,充分利用洪水资源。采用安康水库1943~2011年降雨径流资料,结合天气系统成因分析和数理统计分析等方法,研究确定安康水库的汛期分期方式。结果表明,天气系统成因分析和数理统计分析得到的结果较为一致,分期方式能够较好地反映汉江流域夏秋两汛的特性,安康水库的汛期分期推荐方案为:51~620为前汛期;621~731为夏汛期81~820为过渡期;821~1031为秋汛期

Abstract: Identification of flood season can provide scientific basis and technical support for multiple control of flood limited water level, and make full use of flood water resources. Using the daily rainfall and runoff data from 1943 to 2011 of the Ankang reservoir basin, the flood seasonality is determined by rational method and statistical analysis methods. The results are consistent and can reflect the characteristic of two main flood seasons (summer and autumn) in the Hanjiang basin, the flood seasonality of Ankang reservoir is divided into pre-flood season (1st, May-20th, June), summer flood season (21st, June-31st, July), interim flood season (1st, August-20st, August) and autumn flood season (21st, August-31st, October).
