Abstract

The purpose of our work is to carry out plant community ordination by means of multidimensional scaling to reveal optimum ways of preliminary transformation of data and the similarity/dissimilarity measure, to identify multidimensional dimensions in terms of edafic properties and phytoindicator scales and to reveal character of interrelations of matrixes of plant community, phytoindicator scales and edafic properties. The received results testify that edafic and climatic scales matrixes bear the complementary information on edaphotop properties and possibly climatop. Most possibly that climatic scales at large-scale level bear the specific information on properties of environment. It is difficult to confirm, whether character of this information to adequate nominative properties of a scale at macrolevel is. But with confidence it is possible to say that climatic phytoindicator scales allow to differentiate ecological conditions in biogeocoenosis at large-scale level. Thus, at the given stage we tend to phenomenological interpretation of value of climatic phytoindicator scales at large-scale level. Keywords : multidimensional scaling, community structure, phytoindicator scales, Mantel test

植物指示剂估算植物群落结构的多维尺度

本研究的目的是通过多维尺度对植物群落进行排序，揭示数据初步转换的最佳方法和相似/不相似度量，确定土壤特性和植物指示尺度的多维维度，揭示植物群落、植物指示尺度和土壤特性矩阵的相互关系特征。得到的结果证明，地形和气候尺度矩阵具有地形特征和气候特征的互补信息。最可能的是，大尺度的气候尺度承载着环境特性的具体信息。这一信息在宏观层面上是否具有足够的标尺性质，尚难确定。但有信心地说，气候植物指示尺度可以在大尺度上区分生物地质群落的生态条件。因此，在给定的阶段，我们倾向于在大尺度上对气候植物指示尺度的价值进行现象学解释。关键词:多维尺度;群落结构;植物指示剂尺度
