The Barguzin depression bottom is an area with sandy lands (Ivanov, 1960). This depression is one of the largest around the Lake Baikal (Florensov et al., 1965). Its internal field are accumulative surfaces, formed by Pleistocene sands, so-called “kujtuns” (Forest, Suvinsky, Lower, and Upper), are located as stripes of variable width, replacing each other from the north-west to the south-east (Fig. 2 A-D). Aeolian processes are most dynamic on weakly sod and bare sands: in the lower part of the Argada river, in the basins of Ina, Ulan-Burga, Zhargalanty rivers, and in the marginal parts of the steppe “kuytuns” (Fig. 3, 4). The results of aeolian processes are dunes and ridge-basin relief. This publication continues the series of papers (Dulepova, Korolyuk, 2013, 2015; Dulepova, 2016) on psammophytic vegetation of Baikal Siberia (Irkutsk region, the Republic of Buryatia, and the Trans-Baikal region). The paper is based on the analysis of 116 geobotanical relevés obtained in the course of the field studies in 2009–2014 in the Barguzinsky and Kurumkansky districts of the Republic of Buryatia. Four relevés are taken from the literature (Shchipek et al., 2002). Three diagnostic species of the class Brometea korotkiji Hilbig et Koroljuk 2000 (Bromopsis korotkiji, Corispermum sibiricum, Carex sabulosa) occur on the studied sandy lands. Among species of the order Oxytropidetalia lanatae Brzeg et Wika 2001 (Brzeg, Wika, 2001) such species as Artemisia ledebouriana, Chamaerhodos grandiflora, Oxytropis lanata have high constancy and often dominate in communities. When comparing new syntaxa with the previously described alliances (Oxytropidion lanatae Hilbig et Koroljuk 2000, Aconogonion chlorochryseum Dulepova et Korolyuk 2013 and Festucion dahuricae Dulepova et Korolyuk 2015) it was found that they are closer to the alliance Festucion dahuricae. However, Artemisia xanthochroa, Caragana buriatica, Festuca dahurica, Thymus baicalensis, and Ulmus pumila, commom in the Selenga river middle mountains, are absent in the study area (Korolyuk, 2017). The psammophytic fraction of the flora of the study area is not very peculiar. Only two endemic species (Oxytropis bargusinensis and Aconogonon bargusinense) are recorded on the sands of the Barguzin depression. 5 associations, 3 subassociations and 3 communities of the class Brometea korotkiji and 1 association of the class Cleistogenetea squarrosae Mirk. et al. ex Korotkov et al. 1991 (Table 1) are established as new.

摘要

现代风成景观占据了外贝加尔的大片领土。Barguzin凹陷底部是一个沙地区域(Ivanov, 1960)。这个洼地是贝加尔湖周围最大的洼地之一(Florensov et al.， 1965)。它的内部区域是由更新世砂形成的堆积面，即所谓的“kujtuns”(森林、苏温斯基、下层和上层)，它们位于可变宽度的条纹中，从西北到东南相互替换(图2 A-D)。风成过程在弱草皮和光秃秃的沙地上最具动力:在阿尔加达河下游，在伊纳河、乌兰-布尔加河、扎加尔兰提河流域，以及在草原的边缘地区(图3、4)。风成过程的结果是沙丘和山脊-盆地起伏。本出版物延续了一系列论文(Dulepova, Korolyuk, 2013, 2015;Dulepova, 2016)贝加尔湖西伯利亚(伊尔库茨克地区，布里亚特共和国和跨贝加尔湖地区)的沙生植被。本文基于2009-2014年布里亚特共和国Barguzinsky和Kurumkansky地区实地研究过程中获得的116个地球植物学相关数据的分析。四个相关的数据取自文献(Shchipek et al.， 2002)。在研究的沙地上有3种Brometea korotkiji Hilbig et Koroljuk 2000的诊断种(Brometea korotkiji, Corispermum sibiricum, Carex sabulosa)。在毛细叶叶蒿目植物Brzeg et Wika 2001 (Brzeg, Wika, 2001)中，ledebouriana、Chamaerhodos grandflora、毛细叶叶蒿(Oxytropis lanata)等物种具有较高的稳定性，在群落中往往处于优势地位。将新分类与先前描述的联盟(Oxytropidion lanatae Hilbig et Koroljuk 2000, Aconogonion chlorchryseum Dulepova et Korolyuk 2013和feucion dahuricae Dulepova et Korolyuk 2015)进行比较，发现它们更接近于feucion dahuricae联盟。而色伦尕河中部山区常见的黄花蒿(Artemisia xanthochroa)、锦鸡儿(Caragana buriatica)、羊蹄草(Festuca dahurica)、百里香(Thymus baicalensis)和榆木(Ulmus pumila)在研究区均未发现(Korolyuk, 2017)。研究区植物区系的沙生植物部分并不十分特殊。巴尔古津洼陷的沙地上只记录到两种特有种(棘足棘虫和棘足棘虫)。Brometea korotkiji纲5个协会、3个亚协会和3个群落，Cleistogenetea squarrosae Mirk纲1个协会。等，如Korotkov等，1991年(表1)被建立为新的。科罗特基溴溴联系法(表2,6-17)。命名类型(holotypus hoc loco):表2，相关资料6(野外编号-和10-200)，布里亚蒂共和国，Kurumkansky地区，Kharamodun村西南2公里，沙丘的凸起峰)，54.18734°N, 110.48333°E，海拔473 m a.s.l, 2010年7月31日，作者- N.

Psammophyte vegetation of the Bargusin depression (Republic of Buryatia)

Modern aeolian landscapes occupy large territories in Transbaikalia. The Barguzin depression bottom is an area with sandy lands (Ivanov, 1960). This depression is one of the largest around the Lake Baikal (Florensov et al., 1965). Its internal field are accumulative surfaces, formed by Pleistocene sands, so-called “kujtuns” (Forest, Suvinsky, Lower, and Upper), are located as stripes of variable width, replacing each other from the north-west to the south-east (Fig. 2 A-D). Aeolian processes are most dynamic on weakly sod and bare sands: in the lower part of the Argada river, in the basins of Ina, Ulan-Burga, Zhargalanty rivers, and in the marginal parts of the steppe “kuytuns” (Fig. 3, 4). The results of aeolian processes are dunes and ridge-basin relief. This publication continues the series of papers (Dulepova, Korolyuk, 2013, 2015; Dulepova, 2016) on psammophytic vegetation of Baikal Siberia (Irkutsk region, the Republic of Buryatia, and the Trans-Baikal region). The paper is based on the analysis of 116 geobotanical relevés obtained in the course of the field studies in 2009–2014 in the Barguzinsky and Kurumkansky districts of the Republic of Buryatia. Four relevés are taken from the literature (Shchipek et al., 2002). Three diagnostic species of the class Brometea korotkiji Hilbig et Koroljuk 2000 (Bromopsis korotkiji, Corispermum sibiricum, Carex sabulosa) occur on the studied sandy lands. Among species of the order Oxytropidetalia lanatae Brzeg et Wika 2001 (Brzeg, Wika, 2001) such species as Artemisia ledebouriana, Chamaerhodos grandiflora, Oxytropis lanata have high constancy and often dominate in communities. When comparing new syntaxa with the previously described alliances (Oxytropidion lanatae Hilbig et Koroljuk 2000, Aconogonion chlorochryseum Dulepova et Korolyuk 2013 and Festucion dahuricae Dulepova et Korolyuk 2015) it was found that they are closer to the alliance Festucion dahuricae. However, Artemisia xanthochroa, Caragana buriatica, Festuca dahurica, Thymus baicalensis, and Ulmus pumila, commom in the Selenga river middle mountains, are absent in the study area (Korolyuk, 2017). The psammophytic fraction of the flora of the study area is not very peculiar. Only two endemic species (Oxytropis bargusinensis and Aconogonon bargusinense) are recorded on the sands of the Barguzin depression. 5 associations, 3 subassociations and 3 communities of the class Brometea korotkiji and 1 association of the class Cleistogenetea squarrosae Mirk. et al. ex Korotkov et al. 1991 (Table 1) are established as new.

Yu. Korolyuk. Diagnostic species: Bupleurum bicaule, Iris humilis, Youngia tenuifolia, Oxytropis bargusinensis. According to cluster analysis (Fig. 9) of data from Baikal Siberia, Mongolia, Tuva, and Inner Mongolia (China) the diversity of psammophytic vegetation is mainly determined by the sand land geography, which is reflected at the alliance, order, and class levels. The dynamics of overgrowth of sands is well traced at the association, subassociation, and community levels. Cluster analysis confirmed the attribution of most of the described syntaxa from the Barguzin and Selenga basins in the alliance Festucion dahuricae.
