摘要
对河龙区间各主要支流的场次暴雨洪水开展了研究,利用统计模型、相关分析等方法分析了水利水保措施对暴雨洪水泥沙的影响。结果表明:①1970—2006年河龙区间水利水保工程对洪峰、洪量、沙量的削减程度分别为33.6%、41.3%、38.0%,陕西北片5条支流洪峰、洪量、沙量的削减程度分别为23.7%、41.7%3、0.3%;②水利水保工程对洪量的削减程度最大,沙量次之,洪峰最小,对主要来沙区5条支流的影响程度略小于整个河龙区间的。
The rainstorm and flood in main branches of Hekouzhen to Longmen region of the Yellow River were studied,the conservation projects impacts on flood and sediment had been analyzed by statistical model and correlation method.The results show that： a）for conservation project reasons,the flood peak,flow and sediment reduced by 33.6%,41.3% and 38.0% respectively in the whole region,and by 23.7%,41.7% and 30.3% respectively in five branches in north Shaanxi Province from 1970 to 2006;b）the impacts on the whole region are larger than on the five branches;and the decrease of flow is the largest and the flood peak is the smallest.
