| 摘 要： | 探讨了洞庭湖区第四纪以来的气候变化,初步得出以下规律：更新世气候变化剧烈,气候组合暖湿（温湿）与冷干;全新世气候转为温凉,主要气候组合为温湿与凉干;历史时期气候主要仍温湿与凉干交替,但15 世纪以来出现短暂的温干与凉温期;15世纪以来,气候波动频繁,有愈来愈不稳定的趋向,进入20世纪,旱涝灾害更加。在全球变暖的背景下,预计该区未来气候趋向于暖湿,但不排除暖干的可能性。

| Abstract: | The climatic change in Dongting Lake area since the Quaternary Period is characterized by the following:in the Pleistocene Epoch,it changed strongly and the climatic combinations were humid hot, humid warm and drought cold;in the Holocene Epoch,it became colder and most of climatic combinations were humid temperate and drought cool;in the historical period,except for the most humid temperate and draught cool climatic combinations,humid cool and drought temperate ones also occurred for a short period since 15th century;and the climate change has been becoming more and more unstable since 15th century,and drought and flood waterlogging occurred more frequently in 20th century.In the coming years,it will probably be humid warm,but the possibility of drought warm can't be ruled out. |
