本文在测定珠江口红树群落生物量和生产力的基础上，进一步测定红树群落各组分的氮、磷含量，计算群落氮、磷的贮量、年存留量、年归还量、年吸收量、周转期和富集率，以了解珠江口红树林氮、磷元素的累积和循环状况，为珠江口红树林资源的保护和利用提供科学依据
Based on the determination of the biomass and productivity of the Pearl River Estuary mangrove community, the contents of nitrogen and phosphorus in each component of mangrove community were further measured, and the reserves of nitrogen and phosphorus, annual and annual returns, annual uptake, Turnover and enrichment rate of Pearl River estuary in order to understand the accumulation and cycling of nitrogen and phosphorus in the Pearl River estuary mangrove forest and provide a scientific basis for the conservation and utilization of the Pearl River estuary mangrove resources
