Abstract

The effects of different management measures on the undergrowth diversity of Larix gmelinii forests were determined. The undergrowth vegetation of Xing'an Larch forest under seven different transformation methods was investigated in the Chaocha Forest Farm of the Genhe Forestry Bureau in the northern Daxinganling Mountains. Community composition, structural characteristics, species diversity and biomass of seven different retrofitting methods and one control plot. The results showed that the species composition of Larix gmeliniii under 7 different transformation methods included 34 species of 30 genera and 21 families of shrubs, including 7 species, 7 genera and 7 species of shrub layer, and 20 species, 24 genera and 24 species of common species in the herb layer. The species with the largest proportion in the layer is bilberry, followed by Xing'an rhododendron, and the dominant species of herbaceous layer is quite different. In terms of diversity index, the diversity index of Xing'an larch forest under local tending artificial promotion natural regeneration and transformation measures was low (P<0.05); the study showed that the best tending thinning intensity was between 30% and 40%, different. The impact of the transformation method on the structure and diversity of understory vegetation in Larix gmelinii forest is not only related to the transformation, but also depends on the transformation measures taken.
