| 中文摘要:河北省黄骅市关家堡孔（ＨＧ１），孔深４１．３ｍ，地层连续、化石丰富、分辨率高，其所含微体化石，清楚地揭示了华北平原４万年以来两次大的突发性升温事件，据研究这两次升温事件在时序上与全球性的升温事件是同步的：第一次由冷变暖起始于４００００ａＢ．Ｐ．（沧州海进期）；第二次为１００００ａＢ．Ｐ．（天津海进期）。第一次升温事件（沧州海进期）华北平原的年平均温度比今高７℃左右；比其以前的降温事件期（沧州海进与白洋淀海进之间的海退期）至少高１３℃，如此大幅度的升温事件可能是受西太平洋赤道暖池扩张影响的结果。第一次升温事件期间存在着一个短暂的变冷事件。第二次升温事件期（天津海进期），其年平均温度比今高２～３℃。 |

| Abstract:Two great abrupt warming events have been recognized from the Guanjiabao drill hole in Huanghua County,Hebei Province,North China Plain.The first warming event began about 40000a B.P.(during the Cangzho transgression);the second started in 10000a B.P.(during the Tianjin transgression).Both events are the same as the global warming events in the time scale.The mean temperature was 7℃ higher than the present temperature during the first warming event,and 13℃ higher than the former cooling event(in the regression period between the Baiyangdian transgression and the Cangzhou transgression)in the northeastern part of Nroth China Plain.The expansion of the Western Pacific Warm Pool may be responsible for the significant warming up events in the North China Plain. The mean temperature was 2～3℃ higher than the present temperature during the second warming event. |
