摘要： 本文利用27万条自然灾害史料记载,整理出我国东部及南部85个地区的受灾县次记录,分析了这些记录的可靠性,建立了这些地区1471—1950年的旱涝指数序列,并以北京地区为例,详细说明了利用旱涝县次建立旱涝指数序列的过程,分析了这种方法的可靠性。

Abstract: In this paper,the numbers of the damaged counties(especially for Drought/Flood counties) are extracted from the historical materials in Chian during historical times, and the reliability of them are described. In general, the materials about the number of Drought/Flood counties can be considered as quantitative information of climate.And so, to reconstruct the Dryness/Wetness index series by using these materials, the comprehensive error of the series can be avioded better than by using the description about disasters in historical documents. To show the process of reconstrcting Dryness/Wetness index series by the number of Drought/Flood counties, a case of Beijing is described, and the reliability is discussed.
