摘要: 频谱分析发现泾河中游地区洪水发生具有周期性,比较显著的周期有101年、11年、3.4~2.2年周期等,其中101年和11年周期可以和太阳活动的周期相对应,3.4~2.2年周期则可能与热带海气耦合规律有关,说明太阳活动和低纬海洋大气活动对该地区洪涝灾害都有影响。每个世纪中期是该地区洪涝灾害较为集中的时期。

Abstract: We have done the reanalysis on the data of flood hazards in the mid-reaches of Jinghe River from 1646 to 1949,using the historical document.As a result,it is found that the flood hazards in this area are mostly local ones in a small scale.It is worth to point out that the flood hazards in the study area happened more frequently in the middle of the 20th.Spectral analysis on the flood sequence indicates that there exist periodicities of 101 years,11 years and 3.4-2.2 years in the mid-reaches of the Jinghe Rive.The centennial and quasi-decennial periodicities can be well correlated respectively to those of solar activity;the periodicity of 3.4-2.2 years is probably associated with the activity of tropical air mass,which indicates that both the solar activity and the atmospheric activity in the area of low latitude ocean can influence the frequency of flood hazards in the study region.

Key words: mid-reaches of Jinghe River, flood hazards, periodicities, solar activity, Qing Dynasty
