摘要：本文对平均年龄为5年,天然更新形成的海桑林进行了生物量的测定。乔木层采用相关生长测定法。结果表明,林分总生物量为47.2340t/ha,其中乔木层为19.3608t/ha,灌木层为27.5482t/ha,凋落物为0.3250t/ha。乔木层平均净生产量为3.8702t/ha·a,比马来西亚Matang未管理的同龄红树林的生产量要高些,而比其管理的同龄红树林要低得多。从林分生物量在各层的分配来看,其结构不大合理,应该疏伐一些桐花树,改善乔木树种的生长和更新条件,提高林分生产力。
The paper deals with the biomass and production of average 5-aged Sonneratia caseolaris stand naturally regenerated. The biomass of tree layer was measured by allometric method and that of shrub and litter layer was measured by method of plot harvest. The result showed that the total biomass of the stand is 47.2340 t/ha, in which, tree, shrub and litter layer is 19.3608 t/ha, 27.5482 t/ha and 0.3250 t/ha respectively. The mean net production of tree layer is 3.8702 t/ha. Comparing with the mangroves in Matang, Malysia, the productivity of Sonneratia caseolaris stand in Hainan Island is higher than that of Rhizophora apiculata stand but much lower than that of managed mangroves.The biomass distribution in different layers of the stand is unreasonable, therefore, the shrub of Aegiceras corniculatum should be thinned to improve the growth and regeneration of the trees and increase productivity of the stand.
