摘　　要：红树林是热带、亚热带海岸潮间带的木本植物群落,它是海湾河口地区生态系统最重要的生产者,对保护海湾河口地区的生态平衡起着十分重要的作用。湿地植物生物量是衡量湿地生态系统健康状况的重要标志。红树林生物量的研究,对于了解红树林生态系统的生产规律，提高森林生态系统的生产力，具有十分重要的意义。The biomass of six-year-old Sonneratia apetala Buch-Ham.and Bruguiera gymnorrhiza（L.） Lamk.pure plantation in Nansha were surveyed with both the correlative growth method and the mean sample tree method.The result showed that the biomass of S.apetala was 1 146.08 t·hm-2,in which the aerial part was 869.17 t·hm-2 and the underground part was 276.91 t·hm-2;the biomass of the trunk was 473.79 t·hm-2,which was accumulated as the highest biomass and took up 41.3% of the total.The biomass distribution among organs was in the order of trunkbranchrootbarkflower and fruitleaf.The biomass of B.gymnorrhiza was 55.51 t·hm-2,in which 40.62 t·hm-2 for the aerial part and 14.89 t·hm-2 for the underground part,and the biomass distribution among organs was in the order of trunkrootbranchleaf.The average net productivity of S.apetala was 191.02 t·hm-2·a-1 and the average net productivity of B.gymnorrhiza was 9.26 t·hm-2·a-1.As the population age and initial density of plantation are taken into consideration,both the biomass and productivity of six-year old S.apetala were higher.
