| 摘 要： | 本文是福建九龙江口红树林生态系统研究的一个部分,主要讨论20年生秋茄群落的钾、钠的含量及其生物循环。试验结果表明:秋茄群落现存量中,含有钾、钠总量分别为531.97和2100.36公斤/公顷;其中地上部分分别为296.49和742.91公斤/公顷;地下部分分别为235.48和1357.45公斤/公顷。该群落钾、钠生物循环中年吸收量分別为109.15和353.50公斤/公顷·年,归还量分别为59.37和160.18公斤/公顷·年。存留量为49.78和193.32公斤/公顷·年。它的钠含量比钾含量大,周转期钾需9年比钠需13年为快。

| Abstract: | This paper deals with the accumulation and biological cycle of potassium and sodium elements of artificial 20-year-old Kandelia ccndel community in Jiulong river estuary of Fujian province, China.The main results of the measurements are as follows-1. The amounts of potassium and sodium elements in standing crop of this community were respectively 531.97 kg/ha and 2,100.36 kg/ha, in which the amounts of two elements in aerial part of biomass were(kg/ha) 296.49 for K and 742.91 for Na, and that of below groun... |
