Abstract:

基于1961~2005年淮河流域36个站点的降水时间序列资料,通过定义年降水总量(ATP)、年降水总天数(ATD)、年平均降水强度(ATI)、年平均降水天数(WPA)等降水指标,利用改进的Mann-Kendall趋势检验方法对淮河流域降水时间序列的变化趋势进行检验,从多个方面对淮河流域降水的时空变化进行分析.研究结果表明:1)在1961~2005年间淮河流域年降水总天数呈显著下降趋势,而降水总量呈轻微下降趋势,从而导致淮河流域降水强度上升,这一变化在流域西北部、及上游地区表现最为显著;2)各不同历时降水的发生率和贡献率年际变化数据显示,淮河流域降水历时缩短,而短历时降水事件对总降水量贡献率增大,说明在气候变化影响下,淮河流域水循环加剧,降水过程集中趋势明显,进一步增加了淮河流域短历时洪水及长历时干旱灾害风险
