| 摘 要： | 对大桥泥炭地的孢粉进行了分析和年龄测定.根据孢粉组合、地层特征和14C年龄将剖面划分为4个孢粉带,分别为2 195±70～2 045±70 yr B.P.松为主的松-云冷杉-榛-栎-苔草组合带、2 045±70～1 745±70 yr B.P.苔草为主的松-桦-榛 胡桃-苔草组合带、1 745±70～705±70 yr B.P.松-榛-鹅耳枥-苔草-毛茛组合带和705±70 yr B.P.～1 950 yr A.D.松-云冷杉-桦-苔草组合带.周围植被由温带山地针叶林（类似现今海拔1 100 m以上）、温带针阔混交林下部（类似现今海拔400～600 m）和温带针阔混交林中部（类似现今海拔600～800 m）过渡到温带针阔混交林上部（类似现今海拔800～1 100 m）.相应地，泥炭沼泽经历了孕育期、蓬勃发展期、继续扩张期和消亡期.

| Abstract: | Based on the study of pollen, stratum and 14C dating of Daqiao fen in Dunhua of Jilin Province, four pollen zones were distinguished, i.e., Pinus-Picea-Abies assemblage (2195 +/- 70 to appromimately 2045 +/- 70 B. P., Carex-Pinus-BetulaCorylus-Juglans assemblage (2045 +/- 70 to appromimately 1745 +/- 70 B.P.), Pinus-Corylus-Carpinus-Carex-Ranunculus assemblage (1745 +/- 70 to appromimately 705 +/- 70 B.P.), and Pinus-Picea-Abies-Betula-Carex assemblage (705 +/- 70 to appromimately 1950 AD). The vegetation changed from coniferous forest (similar to the vegetation currently foundover 1100 m a.s. 1. in this area), through conifer-broad-leaved mixed forest (similar to the vegetation currently found between 400-600 m a.s.l.) and conifer-broad-leaved mixed forest (similar to the vegetation currently found between 600-800 m a.s.l.), to conifer-broad-leaved mixed forest (similar to the vegetation currently found between 800-1100 m a.s.l.). Accordingly, Daqiao fen underwent the periods of gestation, fast development, expansion, and dieing out. |
