Spatiotemporal process and climatic background of clustering disasters in China during 1635-1643
In recent years, the study of historical disasters from the perspective of disaster geography focuses on spatiotemporal evolution and series analysis, and the recovery of historical clustering disasters needs attention. The clustering disasters such as drought, locust plagues, famine and epidemic disaster occurred during the 8

Chongzhen years (1635-1643) in the late Ming Dynasty were relatively rare in terms of duration, scope, and level. By sorting out the historical documents and constructing the data set, this paper takes drought and locust plagues as the line to recover the spatiotemporal evolution and correlation between clustering disasters, and clarify the climatic background of this period. The results show that: (1) The development of disasters presented a single peak type of “fast increasing followed by slow decreasing” trend, but the peak years were different. Drought, locust plagues and famine were severely affected during 1638-1641. The epidemic had a lag period and reached its peak in 1641. (2) The drought was widely distributed in the eastern monsoon region of China, and the Huang-Huai-Hai Basin and the lower reaches of the Yangtze River were the core affected areas. The outbreak of locust plagues was relatively concentrated along the lower reaches of the Yellow River and around the lakes, which reflected the obvious “water approaching characteristic”. (3) Compared with drought, locust plagues showed significant spatial correlation and temporal succession, and famine and epidemic disaster presented a lag. Drought significantly promoted the outbreak intensity of locust plagues. (4) During the Little Ice Age, continuous extreme cold and dry climate aggravated the outbreak of locust plagues, which may be related to large-scale circulation or other external environment changes, and the pattern of the disaster chain multiplied the intensity of the situation.
