摘要: 通过对福建三明27年生杉木(Cunninghamia lanceolata)-观光木(Tsoongiodendron odorum)混交林(混交比例2:1)及杉木纯林群落N、P养分循环进行为期2年的研究。结果表明,混交林中杉木和观光木地上各组分的N、P含量大小均为叶>活枝(或皮)>枯枝>干,而根系的则随径级的减小而增大,且观光木各组分的N含量均高于杉木的;混交林群落的N、P总积累量达585.223 kg·hm-2和128.784 kg·hm-2,分别是纯林群落的1.5倍和1.3倍。混交林群落N、P养分年归

Abstract: A study on the cycling of N and P in a pure forest of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook. and a Chinese fir-Tsoongiodendron odorum Chun mixed forest (2 Chinese fir: 1 T. odorum) over two years was carried out in Sanming, Fujian, China. For
