Abstract

TheTarskoe swamp is oneof the largest peatbogs in the central part of theNorthCaucasus, it occupies about 20 ha in the basin between the Lesisty and Pastbishchny ranges (42° 57 ʹ46" N, 44° 43 ʹ32" E; 806 m above sea level [a.s.l.]). The climate is temperate continental with warm and very humid summer and medium cold, snowy winter. The swamp is located in the lower montane belt of broad-leaved forests dominated by Fagus orientalis Lipsky and Carpinus betulus L. with Quercus robur L., and an admixture of Corylus avellana L., Ulmus glabra Huds. and Pyrus caucasica Fed. Swamp vegetation is formed by Carex sp. and Phragmites australis (Cav.) Steud. with Matteuccia struthiopteris L. and Sphagnum sp., with thickets of Alnus glutinosa L. in some places. The swamp was drained for pasture and haymaking in the mid-twentieth century. Two previous studies investigated cores from the Tarskoe swamp (Knyazev et al. 1992; Neishtadt 1955, 1957). However, Neishtadt (1995, 1957) did not provide a dating for the sediment core and Knyazev et al. (1992) did not include the upper part of the core, which might have been removed during peat harvesting. The drilling for the present study was made in 2019 in an undisturbed area of the swamp.

67.高加索中部的Tarskoe沼泽（俄罗斯北奥塞梯）

Tarskoe沼泽是北高加索中部最大的泥炭地之一，位于Lesisty和Pastbishchny山脉之间的盆地（北纬42°57°46“，东经44°43°32”；海拔806米），占地约20公顷。气候为温带大陆性气候，夏季温暖湿润，冬季中冷多雪。沼泽地位于阔叶林的下山地地带，阔叶林主要由东方法格斯（Fagus orientalis Lipsky）和桦树（Carpinus betulus L.）与粗壮栎（Quercus robur L.）以及榛子（Corylus avellana L.）和光榆（Ulmus glabra Huds）的混合物组成。沼泽植被由苔草和芦苇组成。与Matteuccia struthiopteris L.和Sphagnum sp.，在一些地方与Alnus glutinosa L.的灌木丛。20世纪中期，沼泽地被排干，用作牧场和干草生产。之前的两项研究调查了Tarskoe沼泽的岩心（Knyazev等人，1992；Neishtadt 19551957）。然而，Neishtadt（19951957）没有提供沉积物岩芯的年代测定，Knyazev等人（1992）也没有包括岩芯的上部，这些岩芯可能在泥炭采集过程中被移除。本研究的钻探于2019年在沼泽的一个未受干扰的区域进行。

期刊介绍： Grana is an international journal of palynology and aerobiology. It is published under the auspices of the Scandinavian Palynological Collegium (CPS) in affiliation with the International Association for Aerobiology (IAA). Grana publishes original papers, mainly on ontogony (morphology, and ultrastructure of pollen grains and spores of Eucaryota and their importance for plant taxonomy, ecology, phytogeography, paleobotany, etc.) and aerobiology. All submitted manuscripts are subject to initial appraisal by the Editors, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
