摘要: 探讨了广西英罗湾70年生红海榄红树林C、H、N含量、现存贮量、年能量及年O2的净生产。结果表明,红海榄植物体不同组分,C、H、N含量范围分别为43.86-51.65、4.35-5.72和0.28-1.44%.群落C、H、N现存量分别为14117.7、1446.4和158.5g·m-2.群落年净固定C798.51g·m-2、结合H86.31g·m-2和吸收N12.33g·m-2.其中,用于群落增长而年存留C、H和N分别为441.22、45.01和5.37g·m-2,年经凋落物输出C、H和N分别为357.29、41.30和6.96g·m-2.群落年能量净生产量为31227KJ·m-2,年O2净释放量为2129g·m-2

Abstract: Studies on C, Hand Ncontents and storages, annual energy and annual O2 net productions in a 70 years old Rhizophora stylosa mangrove community at Yinluo Bay of Guangxishow that the C, H and N contents in different parts of the plant are 43.86-51.65%,4.35-5.72% and 0.28-1.44%, and their storages in the community are 14117.7,1446.4 and 158.5g·m-2 respectively.The annual net fixed C, Hand N by the communityare respectively 798.51, 86.31 and 12.33g·m-2, among which, annual reserved C, Hand Nare 441.22, 45.of and 5.37 g·m-2, and annual outputs through litter are 357.29,41.30 and 6.96g·m-2 respectively.The annual net production of energy by the community is 31227KJ·m-2, and annual net release of O2 is 2129g·m-2.
