摘要
本文通过对黄淮海地区500年旱涝资料的计算、分析,得出了以旱涝灾害指数作为鉴别干旱的指标,能较确切地反映出新研究范围内各年旱涝灾害程度。这对分析各年灾害程度、探讨灾害的成因以及灾害的变化规律都是有益的。
Having calculated and analysed the data of droughts and floods of past 500 years in Huang(Yellow River)-Huai(Huaihe River)-Hai(Haihe River) region, the paper obtained the index numbers of drought and flood which can be used as indexes for drought appraisal. They can precisely indicate the level of each year's droughts and floods in the mentionedr egion and are very useful for analysing annual level of disasters as well as for studying causes and patterns of hazards.
