摘要: 通过滇西北横断山区4个泥炭剖面的孢粉分析表明,全新世以来本区植被与气候主要经历了5个发展阶段。晚更新世与全新世的界限可定为12000年。各地点的泥炭堆积速率介于0.84~0.30毫米/年之间。

Abstract: Five pollen diagrams reveal palaeophytes and palaeoclimate changes during the Holocene in the North-West Yunnan Plateau of the Hengduan Mountains.The Holocene period can be divided into five stages,the vegetation and climate of each site have nothing in the common with each other. In the North-West Yunnan Plateau,swamp isn’t developed at the same time,the initial stage of swamp-forming is early period of the early Holocene,die out at late period of the middle Holocene.
