本文主要探讨了广西英罗湾64年生红海榄(Rhizophora stylosa)红树群落对Cl、Na的吸收分布和生物循环。结果表明:该群落现存生物量中.库存Cl、Na总量分别为349.39g/m~2和279.8 5g/m (g·Cl/g·Na=1.25,mol·Cl/mol.Na=0.81),其中地上部分别占60.4%和5 6.9%,地下部分别占39.6%和4 3.1%。群落Cl、Na的生物循环为:年吸收量分别为40.18g/m~2和26.56g/m~2;年存留量分别为11.40g/m~2和9.15g/m~2;年归还量分别为28.78g/m~2和17.41g/m ~2;循环系数分别为0.72和0.66。周转期Cl(12年)快于Na(16年)。群落对Cl、Na的富集率分别为2.18和1.8.
In this paper, the distribution and biocycle of Cl, Na in mangrove community of 64-year-old Rhizophora stylosa in Yingloo Bay, Guangxi were studied. The results showed that the total contents of Cl and Na in the community were 349.39g / m 2 and 279.8 5g / m, respectively (g · Cl / g · Na = 1.25, mol · Cl / mol · Na = 0.81) , Of which 60.4% and 59.9% were above ground and 39.6% and 41.1% below ground respectively. The biocirculation of Cl and Na in the community was as follows: the annual uptake was 40.18g / m ~ 2 and 26.56g / m ~ 2, and the annual storage was 11.40g / m ~ 2 and 9.15g / m ~ 2 respectively. Respectively, 28.78g / m ~ 2 and 17.41g / m ~ 2; the cycle coefficients were 0.72 and 0.66, respectively. Turnover Cl (12 years) is faster than Na (16 years). The enrichment rates of Cl and Na in the community were 2.18 and 1.8, respectively.
