长白山落叶松林下笃斯越桔群落生物量的空间分布
Spatial distribution of the biomass of Vaccinium uliginosum community under Larix olgensis forests in Changbai Mountains, Northeast China
摘要
Abstract
An investigation was conducted on the below- and above-ground biomass and its spatial distribution of Vaccinium uliginosum community under Larix olgensis forests in Changbai Mountains. The above-ground biomass of the V. uliginosum community was mainly distributed below the height of 50 cm, and the biomass of the branches with a diameter of 3-5 mm occupied the largest portion. The below-ground biomass accounted for 75. 2% -92. 6% of the total, and was mainly (66.3% -85. 0% ) distributed in dead moss layer where the biomass of fine roots (<1 mm) accounted for 42.6%- 82.7% of the total. In peat layer, the root biomass accounted for 12. 3% -29. 7% of the total. The root biomass of V. uliginosum accounted for 8. 8% -60. 7% of the total root biomass of all plant species, and the fine root biomass of V. uliginosum occupied a great portion. This study provided basis for the rational protection and utilization of V. uliginosum resources and the evaluation of the carbon sequestration of the ecosystem.关键词
