摘要
本文根据方志时期的历史记载及近代的气候资料,建立了华南近五百年(1470—1988)的冬温等级序列,订正增补了旱涝等级序列,根据上述气候序列研究华南的气候变化特征。结果表明,华南冷暖、旱涝有10—12、19—22、31—37、40—45、80、100及120—140年等主要周期;近五百年经历了4次冷暖期的交替;旱涝方面则有3次旱期、4次涝期。
Based on historic presentations in local records and climatological data for South China in modern tomes, a series of grouped winter temperatures is set up for 1470-1988 and that of droughts and floods is also reduced and supplimented. The two series are used to study the characteristics of the climatic change. The result shows that prominent periods exist for durations of cold and warm, droughts and floods at intervals of 10-12, 19-22, 31-37, 40-45, 80, 100 and 120-140 years. In the past 500 years or so, there are 4 alterations of cold and warm years, and 3 lengths of drought and 4 lengths of flood.
