摘要

该出版物介绍了2006年至2019年期间对哈卡斯共和国一些盐湖(Shira、Tus、Ulugkol、Altaiskoe)绿藻进行的植物区系研究的结果。这些湖泊位于纳扎罗夫-米努斯基山间坳陷的切巴科夫-巴拉赫廷斯基和米努斯基盆地的草原地带。研究期间湖泊水体的矿化度为:15.9 ~ 21.9 g/l(设拉湖);52,7 - 115,07 g/l(图斯湖);18,3 - 21,7 g/l (Lake Ulugkol);42,7 g/l (Lake Altaiskoe)。湖水的pH值为碱性- 8,2 - 9,8。在4个湖泊的浮游生物、底栖动物和周围植物中,共发现绿藻30种,隶属于5纲10目17科22属。在调查的所有湖泊中均发现了Cladophora glomerata和Oocystis submarina种。在不同的藻类群落中,与蓝藻原核生物和绿藻硅藻一起,以下物种占主导地位:bratryococcus、chlorelloides、Cladophora glomerata、Cladophora sp.、Dunaliella salina、Hindakia tetrahotoma、Oocystis submarina、Rhizoclonium hieroglyphicum、R. riparium、Spermatozopsis sulsulans、Sphaerocystis planplantonica。其中高活性种为盐藻Dunaliella salina (Ulugkol湖和Altaiskoe湖)、植物球形囊藻Sphaerocystis planplantonica和水下卵囊藻Oocystis submarina (Ulugkol湖),相对发生频率为74 ~ 50%。该地区植物区系的稀有物种有:阿尔泰斯科湖的Picocystis salinarum,图斯湖的Percursaria percursa。在水矿化方面,研究湖泊的绿藻可分为淡水藻、嗜盐藻和多藻三类。

Green algae distribution in some salt lakes of the Republic of Khakassia
The publication presents the results of a floristic study of green algae of some salt lakes in the Republic of Khakassia: Shira, Tus, Ulugkol, Altaiskoe, conducted in the period from 2006 to 2019. The lakes are located in the steppe zone within the Chebakovo-Balakhtinsky and Minusinsky basins of the Nazarov-Minusinsky intermountain depression. The mineralization of water in the lakes for the study period was: 15,9–21,9 g/l (Lake Shira); 52,7–115,07 g/l (Lake Tus); 18,3–21,7 g/l (Lake Ulugkol); 42,7 g/l (Lake Altaiskoe). The values of pH of the water lakes are alkaline – 8,2–9,8. In plankton, benthos and periphyton of 4 lakes we found 30 species of green algae belonging to 5 classes, 10 orders, 17 families, 22 genera. Cladophora glomerata and Oocystis submarina species were discovered in all the lakes surveyed. In different algae communities, along with cyanoprokaryotes and diatoms from green algae, the following species dominated: Botryococcus braunii, Chlorella chlorelloides, Cladophora glomerata, Cladophora sp., Dunaliella salina, Hindakia tetrachotoma, Oocystis submarina, Rhizoclonium hieroglyphicum, R. riparium, Spermatozopsis exsultans, Sphaerocystis planctonica. Among them, highly active species with a relative frequency of occurrence of 74–50 % were: Dunaliella salina (in lakes Ulugkol and Altaiskoe), Sphaerocystis planctonica and Oocystis submarina (in lake Ulugkol). Rare species for the flora of the region are noted: Picocystis salinarum – in lake Altaiskoe, Percursaria percursa – in the lake Tus. In relation to water mineralization, the green algae of the studied lakes belonged to the groups of indifferents, halophiles, and polygalobes.
