摘要

采用Brawn-Blanquet方法和聚类分析对Bolshoy-Agul河流域(萨扬东部)的森林进行了分类。揭示了北亚的两个地带性森林类别——Br.-Bl.等人1939年的Vaccinio–Piceetea Br.-Bl的北方森林和Rhytidio–Laricetea Korotkov等人1999年的半北方森林。北方针叶林主要由东西伯利亚蒙古型的两个目代表——Ledo–Laricetalia Ermakov et Alsynbayev 2004和Lathyro–Laricetalia Ermakov et al.2002。第一个目包括2004年西伯利亚皮诺-Laricion Ermakov和Alsynbayev联盟和两个协会-球果-西伯利亚松和林奈-西伯利亚松。东西伯利亚蒙古型的第二目以千里光-西伯利亚落叶松群落为代表(Krestov等人2009年的Rhododendro–Laricion Ermakov)。北方森林的第三级——Piceo obovatae——Pinetalia sibiricae Ermakov 2013代表了乌拉尔-西伯利亚地理类型的温带群落,分布在中等温暖的栖息地。东西伯利亚蒙古类型的半北方轻型针叶林(Rhytidio–Laricetea Korotkov et Ermakov 1999,联盟Festuco–Laricion Korotkovet Ermakov ex Ermakovet al.2000,Campanulo turczaninovii–Laricetum sibiricae ass.nov.)在最干旱的地区局部发现。分类和比较植物地理分析的结果使纠正东西伯利亚和欧洲西伯利亚地植物亚区之间的边界以及南西伯利亚森林区划系统中的区、省和地区边界成为可能。

Syntaxonomy and geography of light-coniferous and mixed (Pinus sibirica, Larix sibirica) forests of the Bolshoy Agul River basin (Eastern Sayan, Southern Siberia)
The classification of forests in the Bolshoy Agul river basin (Eastern Sayan) was developed using the Brawn-Blanquet method and cluster analysis. Two zonal forests categories in North Asia – boreal forests of the Vaccinio–Piceetea Br.-Bl. in Br.-Bl. et al. 1939 and hemiboreal forests of the Rhytidio–Laricetea Korotkov et Ermakov 1999 were revealed. Boreal coniferous forests are represented dominantly by two orders of the East Siberian-Mongolian type – Ledo–Laricetalia Ermakov et Alsynbayev 2004 and Lathyro–Laricetalia Ermakov et al. 2002. The first order includes alliance Pino sibiricae–Laricion Ermakov et Alsynbayev 2004 and two associations – Carici globularis–Pinetum sibiricae ass. nov. and Linnaeo–Pinetum sibiricae ass. nov. occurring on long-term frozen soils with different moisture regimes. The second order of the East Siberian-Mongolian type is represented by community Senecio nemorensis – Larix sibirica(Rhododendro–Laricion Ermakov in Krestov et al. 2009). The third order of boreal forests – Piceo obovatae–Pinetalia sibiricae Ermakov 2013 represents extra-zonal communities of the Ural-Siberian geographical type occurring in the moderately warm habitats. Hemiboreal light-coniferous forests of the East Siberian-Mongolian type (class Rhytidio–Laricetea Korotkov et Ermakov 1999, alliance Festuco–Laricion Korotkov et Ermakov ex Ermakov et al. 2000, Campanulo turczaninovii–Laricetum sibiricae ass. nov.) are locally found in the driest sites. The results of the classification and comparative plant-geographical analysis make it possible to correct the border between the East Siberian and Euro-Siberian geobotanical subregions as well as the boundaries of districts, provinces and regions in the forest zonation system of Southern Siberia.
