| 摘 要： | 通过对莫莫格泡人工剖面14个样品的孢粉分析笔者划分了3个孢粉带：孢粉贫乏带、蒿-藜麻黄孢粉带和蒿-藜孢粉丰富带，根据孢粉组合，HC测年和沉积相的综合分析认为莫莫格泡是1500aB．P．由古河道洼地为砂丘所堵塞形成的，它经历了河湖转换期、湖泊发育早期和湖泊稳定期，其周围植被由菊科-蒿藜草甸草原逐渐过渡为蒿藜为主的疏林草甸草原和草甸草原，古气候由冷干、温凉偏干向温凉转化，近50年来有暖干化趋势。

| Abstract: | Based on the pollen combination, 14C dating,and depositional facies analysis of Momoge profile in Zhenlai County,Jilin Province,three pollen belts were divided.The results showed that Momoge Lake was formed by blocked paleo-river course depression 1500 years ago,which included three development stages,i.e.,the period when river converted into lake,the early period of lake development,and the steady period.Its corresponding plant types were Artemisia-Chenopodium grassland,Artemisia-Chenopodium grassland accompanied by Betula,and meadow grassland,and its paleo-climate was dry-cold,warm-dry,and then cool-wet,and there was a warm-dry tendency in recent fifty years. |
