dc.description.abstract探讨了福建和溪亚热带雨林主要营养元素通过凋落物的归还动态.结果表明,该森林一年中凋落物不同组分各元素的含量具有波动性,加权平均含量为n>k>CA>Mg>P(落果CA=Mg、落枝CA>k)。通过凋落物归还n、P、k、CA、Mg元素的年库流量,分别为87.41、3.82、40.80、28.81和15.32kgHM(-2),灰分量为284.57kgHM(-2),其中以落叶形式居最大,分别各占总量的73.4%、68.1%、.77.2%、72.9%、74.5%和79.9%;各元素的年库流量与年凋落物量的月分布相一致,有明显的季节性.森林地表残留物n、P、k、CA、Mg元素的累积储量.分别为54.83、2.45、9.69、17.0和9.25kgHM(-2).五种元素在林下地表的滞留时间,分别为n0.61、P0.61、k0.23、CA0.56和Mg0.53年.
dc.description.abstractStudy on the dynamics of nutrient elements returned to the Forest Floor From litterFall in a subtropical rain Forest of Hexi in Fujian Province showed that the contents of elements in various Fractions of litterFall Fluctuated within a year, and the weighted'average contents of elements were in the order N>K>Ca>Mg>P(Ca=Mg For Fruit, Ca>K For branch).The annual Flows of N, P, K, Ca, Mg and ash From litterFall were 87.41, 3.82,40.80,28.81, 15.32 and 284.57kg hm-2, respectively.The pool amounts of N, P, K, Ca and Mg in residues on the Floor were 54.83, 2.45, 9.69, 17.0 and 9.25kg hm-2, respectively.The residence time of the Five elements on the Floor was 0.61, 0.61, 0.23, 0.56 and 0.53 year, respectively.
