摘 要 ：本文是福建省九龙江口红树林研究的一部分，主要讨论20年生秋茄(Kandelia candel) 群落氯元素的累积及其生物循环。试验结果表明，秋茄群落现存量中含有氯总量3864.13公斤／公顷：其中地上部为1287.75公斤／公顷，地下部为2576.38公斤／公顷。该群落氯元素生物循环中年吸收量为626.57公斤／公顷，归还量为271.31公斤／公顷，存留量为355.26公斤／公顷，周转期需14年。

Abstract:This paper is a part of the studies on the mangrove forests in the estuary area of the Jiulongjiang River in Fujian Province. It deals mainly with the accumulation and biological cycle of chlorine in the artificial 20-year-old Kandelia candel community.The main results of the measurements are as follows:1. The amount of chlorine in the standing crop of this community was 3864.13kg·ha-1,in which the amount of the element in the aerial part of the biomass was 1287.75 kg·ha-1 and that of the biomass below ground was 2576.38 kg·ha-1. 2. In the biological cycle of chlorine of this stand, the value of the element in the vegetation uptake was 626.57 kg·ha-1; and that of its return, 27l.31kg·ha-1; and that of its retention 335.26kg·ha-1. 3. The length of the chlorine recycling period is 14 years.
