| 摘 要： | 基于对近年来汉江上游古洪水水文学研究成果的整理和分析,结合文献记载和气候背景分析,对汉江上游5个沉积剖面记录的北宋时期古洪水事件进行了文献考证.研究结果表明,北宋时期为洪水频发期;洪水灾害的影响范围、灾情的严重性以及洪痕沉积规律等表明,汉江上游5个沉积剖面记录的古洪水事件可能是北宋太平兴国七年(982年)六月的一次特大洪水事件.依据树轮、冰芯、石笋等气候代用性指标及历史文献记载,北宋太平兴国七年(982年)正处于北宋980年代气候突变时期,此次古洪水事件可能是对当时气候异常多变的瞬时响应.该研究结果可为汉江上游防洪减灾和水利工程建设提供科学依据.

| Abstract: | Based on the collation and analysis of the paleoflood hydrological study in the upper reaches of the Hanjiang river, the paleoflood events recorded by 5 sedimentary profiles in the upper reaches of Hanjiang river during the Northern Song Dynasty were studied combineing with literature records and climate background analysis. The results show that the Northern Song Dynasty experienced frequent occurrence of floods. According to the influence of flood disaster, the severity of the disaster and sedimentary regularity of the flood mark, the flood events recorded in the upper reaches of the Hanjiang river may be the flood event in June (lunar month) in Taiping Xingguo (982) during the Northern Song Dynasty. Tree-ring, ice core, stalagmites and historical documents show that Taiping Xingguo seven years (982) during the Northern Song Dynasty is in the climate change period. The paleoflood event recorded by 5 sedimentary profiles in the upper reaches of Hanjiang river may be the instantaneous response to the variable climate at that time. The research results could provide scientific basis for flood control, disaster reduction and water conservancy construction in the upper reaches of Hanjiang river. |
