重度火烧对兴安落叶松林群落物种组成及多样性的影响
Species Composition and Diversity of Severe Burned Phytocoenosium After Different Regenerate Years
摘要
Abstract
[Objective] In this study,areas of severe burned larix gmelinii forests have experienced different regenerate years.The purpose was to provide a basis for exploring the forest ecosystem restoration and reconstruction.[Methods] The natural regeneration conditions,community structure characteristics,species composition,community biodiversity were observed.[Results] The results showed that:The alpha diversity index of each community layer in different regenerate years showed a rank of herb layer＞shrub layer＞tree layer.The total number of species had a trend of gradual increase along regeneration.This trend was mainly appeared in herb and shrub layers.The number of species in the herbaceous layer was lower than that of the control plot,except for that in 1996(1996 evere burned,S represents severe burned),while the number of species in the shrub layer were larger than the control plots,except for that in 2003S.[Conclusion] In general,severe fire interference is conducive to the vegetation regeneration and succession.关键词
