明清时期嘉陵江流域中下游洪涝灾害研究
Study on Flood Disasters in the Middle and Lower Reaches of Jialing River Basin in Ming and Qing Dynasties

综合史籍资料和现代科学的研究可以明确看出，明清时期嘉陵江流域干流中下游地区经常遭受洪涝灾害，而清代的洪涝灾害程度远远超过了明代。在19世纪，这类灾害更加频繁，其次是17世纪。洪涝灾害主要发生在夏季和秋季，夏季多发生在农历六月，秋季则多发生在农历八月。从受灾情况来看，嘉陵江下游地区的合川是最严重的，灾情达到了21次，而其中受灾最为严重的地区是苍溪，共有11年受灾，次之是上下游交界的昭化，共有9年受灾。在多次洪涝灾害记录中，嘉陵江流域干流中下游大多为严重洪涝，影响着百姓们的起居生活。
Comprehensive historical records and modern scientific research can clearly see that the middle and lower reaches of the main stream of the Jialing River basin often suffered floods in the Ming and Qing dynasties, and the degree of flood disasters in the Qing Dynasty far exceeded that in the Ming Dynasty. In the 19th century, such disasters became more frequent, followed by the 17th century. Flood disasters mainly occur in summer and autumn, with summer occurring mostly in the sixth lunar month and autumn occurring mostly in the eighth lunar month. From the point of view of the disaster situation, Hechuan in the lower reaches of the Jialing River is the most serious, the disaster reached 21 times, and the most seriously affected area is Cangxi, a total of 11 years of disaster, followed by Zhaohua, a total of 9 years of disaster. In the records of many flood disasters, the middle and lower reaches of the main stream of Jialing River basin are mostly serious floods, which affect the daily life of the people.
