摘要
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钠含量，计算群落钠的贮量、年存留量、年归还量、年吸收量、周转期和富集率，以了解珠江口红树群落钠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 results of the measurement of the biological amount and productivity of the mangrove communities at the mouth of the Pearl River, this paper takes a further measurement of their natrium content and works out their Na storage, their annual values of retention, return and uptake, their turnover periods and enrichment ratio, thus providing a scientific basis for the protection and utilization of the mangrove resources there.
