中文摘要	晋陕蒙毗邻地区是半湿润区向半干旱区过渡地带,对气候变化十分敏感。通过对历史时期寒冻灾害资料进行整理、分析,利用最小二乘法、小波分析等方法,对寒冻灾害进行时空分布特征研究。结果表明: 180 - 1911年的1731年间有144年发生寒冻灾害,范围涉及960县次;秋季寒冻灾害发生频次最多、范围最广,其次为夏季;明清时期寒冻灾害发生频次和县数最多,分别占65. 3 %和64. 2%;历史时期寒冻灾害整体呈波动上升趋势,存在低频、增加、波动增加3个阶段,在时间尺度上表现出200年、110年,80年和20年的周期,其中200年为主周期。寒冻灾害空间分布差异明显,高频中心出现在以榆林为中心的区域,低频中心位于山西部分的兴县、河曲、柳林。寒冻灾害受气候变化和人类活动共同影响,气候的寒冷和转型更多的影响灾害发生广度,而人口密度、生产发展程度则影响寒冻灾害发生频度。
英文摘要	Jin-Shan-Inner Mongolia adjacent area,a climate transition zone,is sensitive to climate change. Based on the statistics and analysis of the historical documents about freezing disasters in Jin- Shan-Inner Mongolia adjacent area,spatial-temporal distribution of the frequency,county-times and intensity were analyzed in the light of the methods of least squares and wavelet analysis. The results show that there were 144 years with freezing disasters in 960 counties of Jin-Shan-Inner Mongolia adjacent area from 180 to 1911. Autumn and summer were frequently prone to disaster. The disasters occurred in Ming and Qing Dynasties accounted for 65. 3%,with 64. 2% of counties suffered. Freezing disasters in historic periods showed a rising trend,experiencing three stages,namely,low frequenting,increasing and rapidly fluctuating. Wavelet analysis shows that there existed freezing disaster cycles of 200,110,80,and 20 years in history with a principal cycle of 200 years. The spatial distribution of the historical freezing disasters varied distinctly,Yulin was the high-frequency disaster center,while Xingxian,Hequ,and Liulin were the low-frequency disaster centers. Climate change and population density,the degree of agricultural development jointly affected the occurrence of freezing disasters. The cold climate and transition have more impact on the extent of freezing disaster,population density and production development affect the frequency of disaster.
