珠江口红树群落钠的累积和循环研究

本文在测定朱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、周围期和富集率，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。

A Study on Natrium Accumulation and Cycle of Mangrove Communities at the Mouth of the Pearl River

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.
