Abstract

The nutrient accumulation and distribution of the aboveground biomass were measured using a stratified harvest method in a secondary hardwood forest in the Guandaushi Long Term Ecological Research site, central Taiwan. Nutrient contents of C, N, P, K, Ca, and Mg in the aboveground biomass were 169,030.71, 2799.77, 52.24, 715.70, 918.72, and 216.41 kg ha^(-1), respectively. Most nutrients in the understory were concentrated below 3.3 m, but in the overstory, they were evenly distributed in each layer below 13.3 m. Although most nutrients accumulated in the stems, the accumulation of N, P, and Ca in the litter layer was higher than in the shrub and herb layer. This result suggested that the litter layer plays an important role in nutrient cycling in Guandaushi secondary hardwood forests. The N content at our research site was quite high compared to that at the Fushan Experimental Forest in northern Taiwan. Factors affecting the nutrient accumulation and allocation in this Guandaushi secondary hardwood forest need to be studied in the future.

台湾中部亚热带次生林地上生物量的养分积累与分布

采用分层采伐法，对台湾中部官道石长期生态研究基地的次生阔叶林地上生物量的养分积累和分布进行了测定。地上生物量中C、N、P、K、Ca、Mg的养分含量分别为169,030.71、2799.77、52.24、715.70、918.72和216.41 kg ha^(-1)。林下养分主要集中在3.3 m以下，林下养分在13.3 m以下各层分布均匀。虽然大部分养分在茎部积累，但凋落物层中N、P、Ca的积累量高于灌木和草本层。说明枯落物层在官道石次生阔叶林养分循环中起着重要作用。与台湾北部福山试验林相比，我们研究点的氮含量相当高。影响官道石次生阔叶林养分积累和分配的因素有待进一步研究。

期刊介绍： The Taiwan Journal of Forest Science is an academic publication that welcomes contributions from around the world. The journal covers all aspects of forest research, both basic and applied, including Forest Biology and Ecology (tree breeding, silviculture, soils, etc.), Forest Management (watershed management, forest pests and diseases, forest fire, wildlife, recreation, etc.), Biotechnology, and Wood Science. Manuscripts acceptable to the journal include (1) research papers, (2) research notes, (3) review articles, and (4) monographs. A research note differs from a research paper in its scope which is less-comprehensive, yet it contains important information. In other words, a research note offers an innovative perspective or new discovery which is worthy of early disclosure.
