摘要:
利用呼图壁河出山口石门水文站1980—2011年日径流量和输沙量实测资料，采用年内不均匀系数、完全调节系数、集中度（期）等方法指标，分析了呼图壁河水沙年内分配及同步变化规律。结果表明：（1）不同年代的径流与输沙年内分配均呈“单峰型”分布，且输沙量较径流量的分配更为集中；（2）近32年以来，径流和输沙的不均匀系数、完全调节系数、集中度都呈缓慢上升趋势，且二者的年际变化都显示出较好的同步性。径流和输沙的集中期同样有着微弱的上升趋势，但输沙集中期略提前于径流集中期。这是由于河流的补给方式和下垫面等综合影响造成的；（3）呼图壁河泥沙年内分配不均匀系数明显高于径流。完全调节系数与不均匀系数的变化趋势基本一致。各个年代冬春季节径流量与同一时段输沙量的变化不同步。
Abstract:
We used the measured data of runoff and sediment discharge the years of Hutubi River Shimen Station in 1980—2011, and analyzed the distribution of Hutubi River sand years and synchronous change rule by using the index coefficient of inhomogeneous, manipulated for monthly and annual variation analysis assisted by using concentration (period) and other methods. The results showed that: (1) the runoff and sediment of different years follow the unimodal type distribution, the distribution and sediment discharge are more concentrated the distribution of the runoff since nearly 32 years; (2) the uneven coefficient of runoff and sediment, completely adjustment coefficient and concentration present the slowly rising trend, and interannual variability of runoff and sediment shows the good synchronicity, runoff and sediment concentration period also has a small upward trend, but the sediment concentration is slightly ahead of runoff because the river supply way and underlaying surface caused by comprehensive effect; (3) The non-uniform coefficient of sediment distribution is significantly higher than the runoff during the year. Complete adjustment coefficient and the change trend of non-uniform coefficient are basically identical. Change of runoff and sediment discharge in winter and spring is out of sync.
