摘要
为探索气温和降水在垂直地带上影响径流的具体关键指标,为未来洪水预测预警提供依据,通过典型实际洪水分析,研究影响洪水产生的关键气象指标。研究发现,巴音沟河山洪主要发生在林线以下的中低山区,主要利用短时降雨、降雨位置和下游时空关系进行防范;高山冰川融雪洪水主要利用日内气温变化、融雪位置和下游之间时空关系进行防范;混合洪水受连续高温和长时间暴雨双重影响。
The key meteorological indicators affecting flood are studied through typical actual flood analysis in order to explore the specific key indicators of temperature and precipitation affecting the runoff in vertical zone,and provide basis for flood prediction and early warning in the future.It is found through research that Bayingou River mountain flood mainly occurs in the middle and low mountain areas below the forest line.The short-term rainfall,rainfall position and the downstream temporal and spatial relationship are mainly utilized for prevention.The high mountain glacier snowmelt flood is mainly prevented through the spatio-temporal relationship among intraday temperature variation,snowmelt location and downstream area.The mixed flood is affected doubly by continuous high temperature and prolonged heavy rain.
