从哈德逊湾低地泥炭芯化石花粉制剂针叶树气孔的鉴定是用来确定当地存在的针叶树代替宏化石分析。本文对云杉、落叶松、松、云杉、落叶松等8种针叶树气孔类型的分化进行了研究。冷杉属，Tsuga mertensiana，Tsuga heterophylla，Chamaaparis nootkatensis，and Thuja type）是完成了一个关键的，图解气孔插图，照片，和测量。化石针叶气孔分析的结果表明，云杉和落叶松到达当地的奥尔巴尼河地区的哈德逊湾低地约4800 BP。在Old Man Bog地区，Larix到达的时间更早，大约6000 BP，但Picea到达的时间晚了2000多年（3700 BP）。比较了化石气孔和花粉的结果。关键词：针叶树气孔，当地针叶树的存在，哈德逊湾低地。
The identification of conifer stomata in fossil pollen preparations of peat cores from the Hudson Bay Lowlands is used to determine the local presence of conifers in lieu of macrofossil analyses. The differentiation of eight conifer stomate types (Picea type, Larix laricina, Pinus sp., Abies sp., Tsuga mertensiana, Tsuga heterophylla, Chamaecyparis nootkatensis, and Thuja type) is accomplished with a key, diagrammatic stomate illustrations, photographs, and measurements. Results of fossil conifer-stomate analyses indicate that both Picea and Larix arrived locally in the Albany River area of the Hudson Bay Lowlands about 4800 BP. In the Old Man Bog area, Larix arrived earlier, about 6000 BP, but Picea arrived more than 2000 years later (3700 BP). Fossil stomate and pollen results are compared. Key words: conifer stomata, local conifer presence, Hudson Bay Lowlands.
