大兴安岭寒温带针叶林群落特征及其物种多样性
Community Characteristics and Species Diversity of Coniferous Forests in Cold Temperate Zone of Daxing'an Mountains
摘要
Abstract
To explore the differences of community characteristics,species diversity and their coupling relationship with environment in different cold temperate coniferous forests in Daxing'an Mountains,and to provide theoretical basis and data support for the scientific management and biodiversity protection of cold temperate coniferous forests in this area.Taking the typical Larix gmelinii forest,Pinus sylvestris var.mongolica forest,Picea jezoensis forest,Picea koraiensis for-est,and Pinus pumila var.pumila forest in Daxing'an Mountains as the research objects,the characteristics of tree layer,shrub layer and herb layer were investigated respectively,and the diversity index,evenness index and richness index were calculated.Redundancy analysis(RDA)was used to explore the coupling relationship between community characteristics and species diversity of five populations.The results showed that the plant species in the cold temperate coniferous forest were poor.The overall tree layer tree species type was single.The average DBH and average tree height of Pinus sylvestris var.mongolica were the highest in the five coniferous forest associations.Vaccinium vitis-idaea was the main species in the shrub layer of five coniferous forests.Deyeuxia purpurea,Pyrola asarifolia subsp.incarnata and Maianthemum bifolium were the main species in the herb layer.These five populations had significantly different diver-sity characteristics and had significant differences in coupling relationships.The diversity index was relatively concen-trated on the left side of the second axis,and was positively correlated with tree height,DBH and number of species in each layer,but negatively correlated with altitude,canopy density,shrub layer coverage and herb layer height.Five typical cold temperate coniferous forests in the Daxing'an Mountains have significantly different community structure and species diversity characteristics.关键词
