Based on the daily precipitation and runoff data of six main embranchments (Haicheng River, Nansha River, Beisha River, Lanhe River, Xihe River, and Taizi River south embranchment) of Taizi River basin in 1967-2006, this paper analyzed the variation trend of runoff coefficient of the embranchments as well as the relationship between this variation trend and precipitation. In 1967-2006, the Taizi River south embranchment located in alpine hilly area had the largest mean annual runoff coefficient, while the Haicheng River located in plain area had the relatively small one. The annual runoff coefficient of the embranchments except Nansha River showed a decreasing trend, being more apparent for Taizi River south embranchment and Lanhe River. All the embranchments except Xihe River had an obvious abrupt change in the annual runoff coefficient, and the beginning year of the abrupt change differed with embranchment. Annual precipitation had significant effects on the annual runoff coefficient.
基于太子河流域1967—2006年6条主要支流(海城河、南沙河、北沙河、蓝河、西河、太子河南支)的日降水和径流数据,分析了各支流径流系数的变化趋势以及该变化趋势与降水之间的关系。1967—2006年,位于高寒山区的太子河南支年平均径流系数最大,而位于平原地区的海城河年平均径流系数相对较小。除南沙河外,各支流的年径流系数呈下降趋势,其中太子河南支和蓝河的下降趋势更为明显。除西河外,各支流的年径流系数均发生了明显的突变,且突变起始年份因支流而异。年降水量对年径流系数有显著影响。
