摘要
根据关中地区历史时期洪涝、干旱、地震、饥荒等灾害史料的分析,统计出自公元前1000年至公元20世纪的3000年间每个世纪灾害发生的频率,并对此时间内历史气候变化进行分析,得出关中地区历史时期气候交替变化较为频繁;重大自然灾害,尤其是旱灾出现频率高,且集中于6-10世纪,14-18世纪。同时分析得出该地区历史时期灾害频数与气候变化有很好的对应关系,即灾害在气候突变时出现频率远高于气候平稳期。
According to the analysis on the historical data of calamities, such as the flood , aridity , earthquake , famine, the frequencies of these disasters during the historical period from 1000 B.C. to 20^th century in the Guanzhong district were obtained. And the conclusions were that the climate changed frequently, more and heavy calamities took place, especially the drought took place during the 6-10th and 14-18th century. This paper also summarized that there was a good corresponding relation between the historic calamity frequency and the climatic change in this district.
