摘　　要：应用气候趋势系数法、累积距平曲线法和滑动t检验法对邯郸市1956年-2010年年降水量和季节降水量系列进行了降水量特征、变化趋势、丰枯变化和突变点分析，结果表明：邯郸市年降水量系列呈下降趋势，但没有发现降水量突变点，春季和冬季降水量系列发生了突变，突变点主要出现在1983年和2000年。通过对邯郸市降雨量特征及变化趋势分析，为水资源开发利用提供科学依据。Applying climate tendency coefficient method, cumulative surface curve method and sliding ＂t＂ test method we carry out an analysis on the rainfall characteristics,the change trend,the dry and wet changes and mutation points of the annual and the seasonal precipitation rainfall in 1956-2010 of Handan. The find is that the annual precipitation series is dropping without mutation points. The mutations point occurred in spring and winter rainfall series, mainly in 1983 and 2000. The analysis on characteristic of precipitation and variation tendency in Handan City could provide scientific basis for exploitation and utilization of water resources.
