摘要

采用非趋势对应分析方法，建立了中西伯利亚南部山区草原植被高单元生态协调模型。该模型是基于326个完整的地球植物学描述和长轴值与气候、土壤-地面和地理参数之间的相关性分析。在两个第一主序轴的空间中，观察到草原植被群落的生态序列，这些生态序列以年、季降水、温度、洋陆性和地石性等气候因子为导向。对观测到的生态地理草原类型进行了分类学解释，并从生态学的角度证实了较高分类单位的等级。

[Ecological interpretation of higher units of steppe vegetation in southern mountains of Middle Siberia via quantitative ordination method].

Detrended correspondent analysis is used for constructing an ecological ordination model of higher units of steppe vegetation in southern mountains of Middle Siberia. The model is based on 326 complete geobotanical descriptions and correlation analysis between the values of major axes and climatic, soil-ground, and geographical parameters. In the space of two first principal ordination axes, ecological series of steppe vegetation coenofloras are observed which are orientated along climatic factors of annual and seasonal precipitation, temperature, oceanity-continentality, and ground stoniness. A syntaxonomic interpretation of observed ecological-geographical steppe types is given, and the hierarchy of higher classification units is substantiated from the ecological point of view.

期刊介绍： Публикуются статьи по теоретическим вопросам биологии, представляющие интерес для биологов любой специальности (вопросы эволюции, экологии, общей таксономии, общей цитологии, генетики, проблемы механизмов приспособления живых организмов к условиям существования, закономерности развития организмов, бионика и т. д.), основанные на новом оригинальном фактическом материале или же подводящие итоги работы того или иного научного коллектива. Помимо теоретических статей, помещаются рецензии на новые книги российских и зарубежных биологов, а также информация о международных конгрессах и общероссийских совещаниях по важнейшим проблемам биологии.
