Biomass and Distribution Characteristics of Pinus tabuliformis Plantations at Different Stand Ages in Taiyuan City
摘要
Abstract
[Objective]To study the biomass changes of Pinus tabuliformis plantations at different stand ages in Taiyuan.[Method]The biomass of tree layer, shrub layer, herb layer and litter layer of Pinus tabuliformis plantation with different stand age (12, 26, 45 a) were obtained by means of average standard wood method and quadrat harvesting method.The distribution characteristics of biomass in different organs and layers of Pinus tabuliformis were analyzed.[Result]The total biomass of different age stands increased with the increase of stand age, and the biomass of 12, 26 and 45 a were 9.79, 217.48 and 276.06 t/hm2, respectively.In the allocation of shrub, grass and litter, the biomass of tree layer was dominant, and it increased with the increase of stand age, followed by litter.The biomass of herb layer and shrub layer was small, and it decreases with the increase of stand age, the biomass of different levels from big to small followed by tree layer, litter layer, herb layer and shrub layer.[Conclusion]The study can provide a scientific basis for promoting rational management and utilization of Pinus tabuliformis.关键词
