Based on the statistics and analysis of freezing disasters from 1260 to 1911 in adjacent areas of Shanxi - Shaanxi - Inner Mongolia,the temporal variations of freezing disasters were obtained by using least squares and wavelet analysis method. There were 116 recorded freezing disasters in these areas,approximately once every 5.61 years on average. The mild,moderate and severe disasters accounted for 10.4%,73.8% and 15.8%,respectively. In August and autumn, freezing disasters occurred most frequently,accounting for 34.1% and 71.9% of the total, respectively. The freezing disaster experienced three stages,namely significant decreasing,fluctuating and rapid increasing. Wavelet analysis showed that freezing disaster cycle was 200a in frequency,and 180a, 55a,25a on the scale. The freezing disaster varied distinctly in spatial distribution,Yulin and Jiaxian were the high - frequency disaster center,while Xingxian was the low - frequency disaster center. The occurrence of freezing disasters corresponded to the long - term climate change obviously. During the climate - transition period and the cold period,there were more counties occurred disasters,but during the mild period there were less of them. Cold caused by cold wave and strong cold air was the main cause of the large - scale freezing disaster in the region.
