摘　　要：对青海湖地区黑马河、泉湾湿地进行了植被样方调查,并由湖岸向外每间隔100～150 m采集表土与苔藓样品进行花粉分析。结果显示,黑马河、泉湾湿地表土花粉与对应样方植被关系密切,花粉组合能较好地反映样方植被特征,同时,桦木属、蒿属、藜科、白刺属、胡颓子科、麻黄科等花粉类型少量出现,为外来花粉。R值分析表明莎草科花粉相对呈高代表性,毛茛科、委陵菜属、禾本科、菊科、报春花科、玄参科等呈低代表性。该研究为在青海湖及其它地区利用花粉重建古植被提供了重要的参考依据。The authors carried out on-site vegetation survey in Heimahe and Quanwan wetlands of Qinghai lake,and 21 surface pollen samples were collected from top soil and moss polsters every 100～150 m away from the lake shore.The results show that pollen assemblages of each sample have clearly relationships with its vegetation quadrates.The majority of the pollen taxa have their percentages closely related to the dominant plants in the vegetation;however,there are some alien pollen taxa,such as Betula,Artemisia,Cheno...
