摘要:
以我国北方主要造林树种油松（Pinus tabulaeformis）为研究对象，通过对陕西省北部（陕北）、中部（关中）、南部（陕南）不同生物气候区内不同龄阶油松人工林下枯落物量及其碳储量进行调查分析。结果表明：幼龄林阶段后，不同生物气候区人工油松林林下枯落物含碳率在不同林分发育时期无明显规律；不同区域人工油松林下枯落物含碳率表现为陕南地区幼龄林含碳量明显高于陕北地区，其它林龄阶段含碳率也未表现出明显规律。陕北，关中和陕南地区油松林枯落物生物量和碳储量，均随林龄的增大逐渐增大；不同纬度下，中龄林和近熟林下枯落物生物量和碳储量呈陕北 > 陕南 > 关中的趋势，并未表现出随纬度降低而减小的趋势。
Abstract:
Based on Pinus tabulaeformis, the main afforestation tree of north China, the litter amount and carbon storage of Pinus tabulaeformis forests in different biological climate regions of northern Shaanxi, Guanzhong and southern Shaanxi were to surveyed and analyzed. The result showed that after young forest stage, at different developmental stages, the litter carbon rate of pine forest in different biological climate regions presented no obvious rule totally. The performance of litter carbon rate of pine forest in different areas was that the litter carbon content of young forest stage in southern Shaanxi is higher than the northern Shaanxi. The litter carbon rate in other forest age stage also showed no obvious rule. The litter material biomass and carbon stocks in three areas were increasing with increase of stand ages gradually. In different latitudes, the litter material biomass and carbon stocks between middle-aged forest and near mature forest appeared in the order of northern Shaanxi > southern Shaanxi > Guanzhong，and it didn’t show decrease trend with decrease of latitude.
