摘要
[目的]研究沿海沙地不同林地土壤碳氮储量.[方法]以福建东山沿海地区林地为研究对象,对各林地不同土层采用剖面法调查和测量各土层全碳、全氮含量,并进行分布格局研究.[结果]同一树种全氮、全碳储量随土层深度增加逐渐减少,不同林地土壤碳储量均集中在0～30 cm厚土层中;4种林地土壤碳氮储量从大到小依次为木麻黄、桉树、湿地松、竹子.[结论]木麻黄相比其他3个树种在沿海沙地具有更好的碳氮储存能力.
Abstract
[Objective] To research the soil carbon and nitrogen storage in different forest lands.[Method] With forest land in Dongshan Area of Fujian Province as the research object,cross-section method was used to investigate the different soil layers in different sample fields.Total carbon and total nitrogen were detected in each soil layer.And distribution pattem was researched.[Result] Total carbon and total nitrogen contents of the same tree species gradually reduced with the increase of soil depth.Soil carbon contents in different forest lands were concentrated in 0-30 cm soil layer.Soil carbon and nitrogen storages in four forest lands were in the order of Casuarina equisetifolia Forst.＞ Eucalyptus robusta Smith ＞ Pinus elliottii ＞ Bambusoideae.[Conclusion] Compared with other three tree species,C.equisetifolia Forst had better carbon and nitrogen storage capacity in coastal sandy land.
