摘要

摘要: 依据宁晋泊南王庄剖面的孢粉、粘土矿物、粒度等数据和Porter等的粒度年龄模型建立时间标尺,划分出2600年来的气候冷暖变化阶段。基本特征如下:孢粉Ⅰ带,大约200aBP~630aBP,气候冷干;Ⅱ带,大约630aBP~1010aBP,气候温暖,上部偏干,下部潮湿;Ⅲ带,大约1010aBP~1165aBP,气候稍冷较湿;Ⅳ带,大约1165aBP~1350aBP,气候温暖潮湿;Ⅴ带,大约1350aBP~1790aBP,气候偏凉干;Ⅵ带,大约1790aBP~2250aBP,气候温暖偏干;Ⅶ带,大约2250aBP~2580aBP,气候寒冷干旱。这与华北地区古文史资料记录的古气候变化有较好的一致性,并具有全球变化意义。

Abstract: Based on the data of sporpollen assemblages, clay minerals, and grain size of the Nanwangzhuang section in the Ningjin lake area, and the timescale established from the age/grain size model by Porter et al, the climatic fluctuations in the last 2600 years are brought out to light as reflected by the seven sporopollen zones.Zone Ⅰ representing a cold and dry climate was ca.200~630 aBP in age, Zone Ⅱ formed in a warm and humid climate in ca.630~1010 aBP, Zone Ⅲ indicative of a cold and humid climate was of an age of ca.1010~1165 aBP, Zone Ⅳ again warm and humid in ca.1165~1350 aBP, Zone Ⅴ, being characteristic of a slightly cool and dry climate was ca.1350~1790 aBP old, Zone Ⅵ, warm and a little dry in ca.1790~2250 aBP, Zone Ⅶ cold and dry in ca.2250~2580 aBP.Such climatic fluctuations well accord with the historical records and may be of a global significance.
