摘　　要：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钾质量分数,计算群落钾的贮量、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钾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 test of the biological amount and productivity of mangrove communities at the mouth of the Pearl River, this paper takes a further test of the contents, storage, annual retention values, return, uptake, turnover periods and enrichment ratio of K in the communities, thus providing a scientific basis for the protection and utilization of the mangrove resources.
