黄河中下游汛期洪水的分期识别
发布时间:2019-02-11 14:24
【摘要】:根据黄河中下游降雨洪水泥沙特性,采用成因分析法、数理统计法、模糊聚类法、分形分析法、圆形分布法等多种方法,对黄河中下游主要洪水来源区和控制站降雨、洪水、泥沙影响因子进行了分期点识别。结果表明:黄河中下游汛期洪水泥沙不仅在时间上有较明显的多分期特点,而且在空间上也有显著的分期时间差异。经综合分析,确定潼关、花园口站汛期洪水分期点为9月10日、10月10日,三门峡—花园口区间汛期洪水分期点为8月20日、10月10日。
[Abstract]:According to the characteristics of rainfall, flood and sediment in the middle and lower reaches of the Yellow River, the methods of cause analysis, mathematical statistics, fuzzy clustering, fractal analysis and circular distribution are used to study the rainfall and flood of the main flood source areas and control stations in the middle and lower reaches of the Yellow River. The influence factors of sediment are identified by stages. The results show that the flood and sediment in the middle and lower reaches of the Yellow River not only have obvious multi-stage characteristics in time, but also have significant difference in space. Through comprehensive analysis, it is determined that the flood staging points of Tongguan and Huayuankou stations in flood season are September 10, October 10, and the flood periods in Sanmenxia and Huayuankou district are August 20 and October 10.
