摘要: 对长白山长白松林林缘、暗针叶林林缘以及笃斯越桔灌丛落叶松林间3个生态过渡带上苔藓植物分布特点的研究表明,苔藓植物盖度与多样性指数可以作为判别林缘生态界面客观性的指标,这些指标均能以y=b·ax进行拟合。通过生态界面系统信息量公式计算了这些指标在生态界面上的信息量,并讨论它们的生态学意义。

Abstract: Investigation of bryophytes at the edges of Pinus sylvestriformis and dark conifer forests as well as the ecotone from Vaccinium uliginosum shrub to Larix olgensis forest near round lake in Changbai Mountain revealed that the cover and diversity indices of bryophytes could be applied to identify the forest eco-boundary in the field. The relationships between these indices (y) with distance (x) on eco-boundary followed y=b·ax. The informative values of the indices were calculated, and their ecological significance was also discussed.

Key words: Bryophyte, Forest eco-boundary, Index, slope aspect, slope position, revegetation approach, species diversity
