摘要: 周秦两汉时期农业灾害发生频繁,种类多样。灾害史料的灾度等级处理和统计结果表明:西周时期发生重大农业灾害8次,春秋战国时期发生重大农业灾害88次,秦汉时期发生重大农业灾害291次。农业灾害在时间分布方面表现出明显的时代特征:①农业灾害在年内季节分布中存在不平衡性;②农业灾害在年际分布中出现多个集中频发的时间区间。而且,愈到后来农业灾害集中发生的现象愈为明显。在空间分布方面,山东、山西地区是周秦两汉时期的农业重灾区。

Abstract: Various kinds of agricultural natural disaster occurred frequently in Zhou, Qin, Western and Eastern Han dynasties. Through dealing with natural disaster historical data, the result shows that the important agricultural natural disaster frequency was 8 times in Western Zhou epoch, 88 times in Eastern Zhou epoch and averaged 1 time every 6.2 years; 291 times in Qin and Han epoch and averaged 1 time every 1.5 years. Agricultural natural disaster showed obvious character in time distributing: ①agricultural natural disaster was not evenly distributed through a year, natural disaster taking place more times in summer and autumn than spring and winter. ②Natural disaster had many concentratedly freqent occurring periods in interannual distribution. There was 1 period in Western Zhou Dynasty, 9 periods in Eastern Zhou Dynasty, 20 periods in Qin and Western Han dynasties, 27 periods in Eastern Han Dynasty. Furthermore, the more late the time was, the more obvious the phenomena of agricultural natural disaster muster occurrence were. In the aspect of space distribution, the sum of various kinds of agricultural natural disaster was 131 times in Shandong disaster section, 113 times in Shanxi disaster section, 15 times in Jiangnan disaster section, 6 times in Northwest disaster section, 4 times in Sichuan disaster section. The heavy disaster areas were Shandong and Shanxi sections in Zhou, Qin, Western and Eastern Han dynasties.
