%X 探讨了广西英罗湾红海榄红树林重金属Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ、Ｃｒ元素的累积及动态。结果表明：植物体不同部位元素的含量范围，分别为Ｃｕ０．４３３～１．２１、Ｐｂ０．３６９～１．８８、Ｚｎ２．９４～７．６６、Ｃｄ０．０２０～０．２３３和Ｃｒ０．３３０～０．５６２ｕｇ／ｇ。林地残留物组分元素含量远高于植物体及凋落物组分含量。该群落Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ、Ｃｒ的现存储量，分别为２８．７３、２５．２５、１４３．６８、３．１４和１４．６１ｍｇ／ｍ２。林地残留物相应元素的储量，分别为２７１．６８、３２３．４１、１９８３．７０、８．１８和３４．４４ｕｇ／ｍ２。群落Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ、Ｃｒ元素的生物循环为：年吸收量分别为１３５１．７０、１６１３．１２、８８０８．３７、２４０．７４和７５９．３０μｇ／ｍ２；年存留量分别为８４２．４６、８０６．９１、４６９４．１０、９４．８８和４６４．８０μｇ／ｍ２；年归还量分别为５０９．２４、８０６．２１、４１１４．２７、１４５．８６和２９４．５０μｇ／ｍ２；周转期分别为５６、３１、３５、２２和５０年；流动系数Ｃｄ＞Ｐｈ、Ｚｎ＞Ｃｕ、Ｃｒ。
