尽管日本的高山和亚高山高沼地生态系统的生态，保护和文化意义，在这些生态系统中的植物群落的物种组成的模式还没有得到充分的描述。本研究的目的是分类和描述的高沼地植物群落的物种组成，并检查分类的社区类型和测量的环境变量之间的关系在亚高山带的北方日本。植物群落可划分为6个类型，其中指示种最强的分别是五瓣山蚂蝗、裂齿花、拟海桑、尖球越橘、苔草和玉簪。这些类型间物种组成的差异主要与土壤溶液pH值和电导率以及海拔和温度的变化有关。每个群落类型代表了植物物种的独特组合，以及一些稀有和濒危物种。通过提供具有代表性的高沼地群落类型的指标来描述和分类植被，应有助于识别和保护这些有价值的群落。
Despite the ecological, conservation, and cultural significance of Japan’s alpine and subalpine moorland ecosystems, the patterns of species composition in plant communities in these ecosystems have not been fully described. The objectives of this study were to classify and describe the species composition of moorland plant communities and to examine the relationships between the classified community types and measured environmental variables within the subalpine zone of northern Japan. Plant communities were sorted into six types, whose strongest indicator species wereSieversia pentapetala,Schizocodon soldanelloides,Moliniopsis japonica,Vaccinium oxycoccos,Carex thunbergii, andHosta sieboldii, respectively. The differences in species composition among these types were mainly related to the variations in soil solution pH and electric conductivity and in elevation and temperature. Each community type represented a unique combination of plant species, with some rare and endangered species. Describing and classifying the vegetation by providing indicators for a representative range of moorland community types should facilitate the identification and conservation of these valuable communities.
