dc.description.abstract[中文文摘]本文是海南东寨港红树林研究的一部分,主要讨论55年生海莲林的K、Na元素的累积和生物循环。试验结果表明:在海莲群落现存量中,含有K、Na总量分別为669.9和2951.3kg/ha;其中地上部分别为425.6和908.9kg/ha,地下部分别为244.3和2042.4kg/ha。该群落的k、Na元素的生物循环中,年吸收量分别为89.6和204.4kg/ha,归还量为49.0和99.8kg/ha,存留量为40.6和104.6kg/ha。K的周转期为14年比Na30年为快。[英文文摘]This paper is a part of studies of the mangrove forests in Dongzhai harbour of Hainan island, China. It deals mainly with the accumulation and biological cycle of K and Na elements of 55-year-old Bruguiera sexangula community.The main results of the measurements are as follows:1. The amounts of K and Na elements in standing crop of this community were 669.9kg/ha and 2591.3kg/ha in which the amounts of two elements in aerial part of biomass were 425.6 for K and 908.9 for Na (kg/ha), and that of below ground biomass were 244.3 for K and 2042.4 for Na(kg/ha) respectively.2. In biological cycle of K and Na of this stand, the annual value of vegetation mineral uptake were 89.6 for K and 204.4 for Na(kg/ha), of its return were 49.0 for K and 99.8 for Na(kg/ha) and of its retention were 40.6 for K and 104.6 for Na(kg/ha), respectively.3. The turnover period of K (14 yrs.) is faster than that of Na (30 yrs.)zh_CN
