摘要: 选取史料中1480~1940年间共460年的旱涝灾害记录,采用湿润指数法建立湿润指数(I)序列,并用最远距离法作聚类分析,讨论了广东省在15~19世纪末期间总体和不同冷暖时期的旱涝区域分布状况。结果表明:(1)113°E经线似乎可以看作是广东省一条重要的气候特征线,该经线以东、以西的旱涝分区界线大致分别沿经向、纬向分布;(2)粤西、粤北是广东省旱涝区域分异变化较大的地区,粤东在不同时期也有所变化,珠三角地区则是较为稳定的涝灾多发区;(3)不同冷暖时期的旱涝分区既有大致相同的特征,又有一定的差异。文章认为以上结果可能是由于广东主要受东亚夏季风影响,一定程度上也受印度夏季风影响及东亚气候系统发生改变等共同作用的结果。

Abstract: Based on the historical records of the drought disasters and the waterlog disasters during the 15th-19th centuries, the dry-wet regional differentiation changes of Guangdong Province during the historical periods are discussed in this paper, and the dry-wet distribution features of the studied area in the different stages of the LIA are also discussed. From the analyses of the dry-wet index data of the studied area, we can draw some conclusions as follows:(1)The 113癊 longitude line seems to be regarded as an important characteristic boundary of Guangdong Province, and there are different characteristics of the dry-wet regional differentiation patterns in the east and the west area of the boundary.(2)There were some more and bigger changes of the dry-wet regional differentiation patterns of different stages in the west and the north of Guangdong Province, and there were also some changes in the east of the Guangdong Province. (3)By and large, there were some common characters and still some differences in the dry-wet regional differentiation patterns of different cold and warm stages. According to these analysis results, the conceivable reasons are also discussed in this paper.
