摘要
将黄河流域主要控制站/区间的降雨、径流、洪水资料系列延长至2010年并分析其变化特点,在对实测径流还原的基础上,通过降雨径流关系变化分析下垫面变化对径流系列一致性影响,并采用多种方法进行一致性处理,提出3种下垫面情景的天然径流系列并推荐近期I下垫面情景的黄河设计径流成果。分析了影响洪水一致性的因素,对主要影响因素进行还原,对影响黄河中下游常遇洪水量级的因素进行还现,提出黄河流域各站天然设计洪水及中游现状下垫面5年一遇及以下设计洪水。
The data series of rainfall, runoff and flood at the main sites or reaches in the Yellow River basin were extended up to 2010 and its changing characteristics were analyzed. Based on the runoff reduction, the influence of the underlying surface change on the consistency of hydrological data series were analyzed through the relationship change between rainfall and runoff. By taking consistency treatment with different methods, this paper proposed 3 runoff series in different underlying surface stages, and the design runoff result of underlying surface stage I was recommended. The natural design flood of Yellow River basin and the design flood occurred every 5 years or below of recent stage II underlying surface in the middle reaches were presented by analyzing the influencing factors of the flood consistency, taking reduction of the main influencing factors and the influencing factors of frequent flood magnitude in the middle and lower reaches in the Yellow River.
