| 摘 要： | 福建九龙江口红树林生态系统研究的一个主要部分。通过对秋茄红树群落凋落物进行为期１１ａ（１９８２～１９９２年）逐月连续测定。结果表明：凋落物产量年际波动在６５１．２～１１０８．６ｇ／ｍ２ａ，１１ａ平均为８６２．９ｇ／ｍ２ａ，其中，叶占总量的６３．３％，枝１５．９％，果１５．３％，花５．５％。不同年份凋落物量变化率（Ｒ）为１．７。１年中凋落物量以夏季＞秋季＞春季＞冬季。凋落物能流量达１２７０２～２１６６４ｋＪ／ｍ２ａ，年际均值为１６８３２ｋＪ／ｍ２ａ，其中春季３８４７，夏季６５５７，秋季４２１４，冬季２２１４（ｋＪ／ｍ２）。各组分能流量分别为：落叶１０７５６，落枝２６８３，落花９３０，落果２４５３（ｋＪ／ｍ２ａ）。大量凋落物可为近海河口海洋生物提供可持续利用的有机物质和能量来源。

| Abstract: | This paper is a part of the studies on the mangrove ecosystem in the estuary of Jiulongjiang River in Fujian Province.The litterfall of Kandelia candel mangrove community was collected for a period of 11 years from 1982 to 1992.The results showed that the annual litter production ranged from 651 2 to 1108 6 g dw/m 2·a.The mean value was 862 9 g/m 2·a of which litter leaf comprised 63 3%,branch 15 9%,fruit 15 3% and flower 5 5% respectively.The yearly litterfall fluctuation rate was 1 70.Seasona... |
