通过对明清小冰期关中地区历史资料的搜集、整理和分析,对该时期关中地区的冻灾发生频率做了统计。结果表明:该时期冻灾的发生呈现波动变化,1451-1500A.D.(明景泰-明弘治)、1571-1730 A.D.(明隆庆-清乾隆)、1831-1910 A.D.(清道光-清宣统)这三个时期冻灾发生的频率较高,而1501-1570 A.D.(明弘治-明隆庆)、1731-1830 A.D.(清雍正-清道光)冻灾发生的频率较低。且冻灾的灾害程度与冻灾的发生频率密切相关,冻灾发生频率较高的时期,灾害的程度也较重。此外,与这一时期该地区的旱灾发生频率统计结果对比分析表明,冻灾与旱灾的发生频率基本上为同步变化。旱灾与冻灾的同步增多,对当时的社会经济发展、农业生产、社会稳定、人口数量变化等方面产生了重要影响。
By collecting, sorting and analyzing the historical data of the Guanzhong area in the Ming-Qing Small Ice Age, the frequency of the freezing-disaster in the Guanzhong area during this period was counted. The results show that the occurrence of the frost disaster during this period fluctuated, 1451-1500A.D. (Ming Jingtai - Ming Hongzhi), 1571-1730 AD (Minglongqing - Qingqianlong), 1831-1910 AD (Qingguangguang - Qingxuantong) The frequency of cold disasters in these three periods was higher, while the frequency of occurrences of cold disasters in 1501-1570 AD (Ming Hongzhi - Ming Longqing) and 1731-1830 AD (Qing Yongzheng - Qingdao Guang) was relatively low. The extent of the disaster and the frequency of the disaster are closely related to the frequency of the disaster. During the period when the frequency of the disaster is high, the degree of disaster is also serious. In addition, a comparative analysis with the statistics of the frequency of drought in the area during this period shows that the frequency of the occurrence of the freeze-up and drought is basically synchronous. The increase in the synchronization of drought and cold disasters has had a significant impact on the social and economic development, agricultural production, social stability and population changes at that time.
