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2195±70~2045±70yr B.P.松为主的松-云冷杉-榛-栎-苔草组合带、2045±70~1745±70yr B.P.苔草为主的松-桦-榛-胡桃-苔草组合带、1745±70~705±70yr B.P.松-榛-鹅耳枥-苔草-毛茛组合带和705±70yr B.P.~1950yr 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1100m以上)、温带针阔混交林下部(类似现今海拔400~600m)和温带针阔混交林中部(类似现今海拔600~800m)过渡到温带针阔混交林上部(类似现今海拔800~1100m).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.

摘  要:
Based on the study of pollen,stratum and 14 C dating of Daqiao fen in Dunhua of Jilin Province,four pollen zones were distinguished,i.e.,Pinus-Picea-Abies assemblage ( 2 195 ±70~ 2 045 ±70 B.P.,Carex-Pinus-Betula-Corylus-Juglans assemblage ( 2 045 ±70~ 1 745 ±70 B.P.),Pinus-Corylus-Carpinus-Carex-Ranunculus assemblage ( 1 745 ±70~705±70 B.P.),and Pinus-Picea-Abies-Betula-Carex assemblage (705±70~ 1 950 AD).The vegetation changed from coniferous forest (similar to the vegetation currently foundover 1 100 m a.s.l.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~ 1 100 m a.s.l.).Accordingly,Daqiao fen underwent the periods of gestation,fast development,expansion,and dieing out.
