| 摘 要： | 本文讨论广西山口英罗湾中红海榄群落的氮、磷含量及其生物循环。结果表明,红海榄群落现存量中,含氮、磷总量分别为221.15和13.27g/m~2。其中地上部分别为134.90和8.73g/m~2;地下部分别为86.25和4.54g/m~2。该群落的氮、磷元素生物循环中,年吸收量分别为12.91和1.27g/m~2,年存留量分别为7.04和0.65g/m~2;年归还量分别为5.86和0.61g/m~2。富集率分别为1.11和1.60。群落各组分的氮含量均大干磷含量;周转期氮需38a,比磷(22a)慢。

| Abstract: | In this paper the accumulation and biological cycle of N and P elements of Rhizophora styloxa community in Yinluo Bay Guangxi.have been studied.It is measured that the amounts of N and P in the standing crop of this community were 221. 15g/m2 and 13. 27g/m2,of which the amounts of the two elements in biomass above ground were N 134. 90g/m2 and P 8. 73g/m2 and in the biomass under ground were N: 86. 25g/m2 and P 4. 54g/m2 .respectively.In the biological cycle of N and P of this, stand, the annual uptake was N 12. 91g/m2 and P 1. 27g/m2,and the retention was N 7. 04g/m2 and P 0. 65g/m2,and the return was N: 5. 86g/m2 and P 0. 61g/m2,respectively.The enrichment ratios of this community were 1. 11 for N and 1. 60 for P. The speed of N recycling period (38 years) is lower than that of P(22 years). |
